2SAFETY OVERVIEW
This section of the document reviews specific safety precautions to observe when installing,
operating or working around the S320 OCS.
To ensure the safety of personnel, the following actions should be implemented prior to
installing the S320 OCS:
It is recommended that a pre-installation site survey be performed; review the
completed site survey for accurate site information.
Become familiar with the safety precautions, notes and warnings contained in this guide.
Observe all weight cautions related to handling equipment. Make sure that adequate
personnel and resources are available to safely lift and transport the S320 OCS during
installation.
Locate power sources and prepare to observe all safety precautions pertaining to
connecting and applying electrical power.
Make sure to implement all electrostatic discharge (ESD) prevention measures when
handling the S320 OCS.
Inspect the installation site for sources of laser light and take all applicable precautions
when near such sources.
Exercise all applicable precautions when moving and handling hazardous materials such
as alcohol and compressed gas.
Make sure to implement the prescribed precautions for handling and cleaning optical
fiber.
2.1 Laser Safety
It is especially important to observe the proper precautions when working with or around
lasers. The following subsections describe the potential risks associated with laser technology
and the recommended procedures for using it safely.
2.1.1 General Precautions
The S320 OCS switches coherent (laser) light between input and output optical-fiber
terminations. The range of the light wavelengths passed through the equipment is outside the
visible spectrum. Because the unaided human eye cannot detect its presence, this light can pose
a serious health hazard.

S320 OCS Hardware User Guide
Doc. Part No. 460167-00

Rev. B7
Page 12 of 46
If the hazard is not mitigated through the use of proper safety equipment and the observance
of safety precautions, blindness can result. This section presents general safety measures that
must be observed by personnel working on or around the S320 OCS to reduce or eliminate the
risk of injury from laser radiation.
Use of controls, adjustments or procedures other than those specified in this
guide could result in hazardous radiation exposure.
The S320 OCS can switch the laser energy supplied by any one of the input
fiber-optic cables to any one of the output fiber-optic cables. To avoid injury, all of
the switch’s optical connectors must either be attached to a fiber-optic cable that
is part of a closed optical system or capped with the supplied connector covers.
Under no circumstance should attempts be made to operate this equipment with
a fiber-optic connector that is uncapped or disconnected from a fiber-optic cable
that is part of a closed optical system.
All service to this device that requires removal of the chassis panel must be
performed by the manufacturer or its authorized agent(s).
Personnel working near, or in the vicinity of, any equipment carrying optical traffic may not be
aware of possible exposure to laser light escaping from uncovered connectors.
To avoid possible injury from unintended exposure to laser radiation, make sure to observe the
following precautions:
Always keep fiber cables connected to all of the S320 OCS connectors, regardless
of whether the fiber termination is providing an active cross-connection. If a cable
is not attached to a connector, make sure the connector is capped. In addition to
preventing accidental exposure to a light source, capping the connector will help
prevent contamination of its fiber-optic surfaces by dust or other particulate matter.
Never look directly into the end of a fiber or into any optical connector. There is no
warning when the connector is connected to a light source.
Always wear the appropriate laser safety glasses when working around a laser source.
When evaluating protective eyewear, be sure to consider the laser power, wavelength
and manufacturer class warnings for the laser device being used.

2.1.2 Laser Sources
The S320 OCS generates Class 1 laser light, but it passes higher-powered laser light from external
sources. The switch passes laser light through its fiber terminations when traffic-carrying fibers
are connected to the switch.
2.1.2.1 Class 1 Laser
The S320 OCS uses a Class 1 laser internally as a test source. Light from this laser could
potentially be available at a fiber termination.
The S320 OCS is certified as a Class 1 laser product per the requirements of the U.S.
Federal Product Performance Standard for Laser Products contained in the regulations
in 21 CFR 1040.10. Class 1 laser products are not considered to be hazardous;
however, lasers more powerful than Class 1 may be connected to the S320 OCS.
Although the S320 OCS has no laser sources higher than Class 1, the total optical
power through the equipment—and potentially available at any one of the fiber
terminations, split-out cable connectors, patch-panel cables or patch-panel coupling
sleeves—could aggregate to the level of a Class 4 (highly hazardous) source.
2.2 Electrostatic Discharge
System components that contain integrated circuits can be damaged by static electricity. Static
electricity potentials develop through the movement of human bodies and are released as
Electrostatic Discharges (ESDs) whenever they come in contact with other objects. Dry air
allows greater static charges to accumulate, but because potentials high enough to damage
circuits can occur anywhere, taking precautions against ESD is imperative when working around
the S320 OCS.
The ESD symbol shown here appears on packaging and other items as a reminder to
take the necessary precautions to prevent electrostatic damage to the S320 OCS.

To reduce the possibility of ESD damage, most equipment racks provide grounding jacks into
which anti-static wrist straps can be plugged. Be sure to observe the following precautions
whenever working with the S320 OCS:
Always wear a tested and verified grounded wrist strap to prevent ESD, making sure
the wrist strap is plugged into a grounding jack.
Observe warning labels on bags and cartons. Whenever possible, do not remove a
module from its antistatic packaging until it is to be installed in the rack.
Always store and transport any module in antistatic packaging.
Keep all static-generating materials such as plastic foil wrappers, other plastics,
Styrofoam and cardboard containers away from the S320 OCS.
Maintain ambient humidity within the 20% to 85% limits specified for operation of
the S320 OCS.
2.3 Optical Connections
2.3.1 Keeping Fiber Connectors Clean
Optical fiber connectors require special handling to mitigate contamination from dust and
debris that could increase insertion loss. Contamination during connection of the connector
surface perpendicular to the light propagation can increase insertion loss and back-reflection.
Once a pair of clean connectors is mated, however, it is unlikely that further contamination will
occur until the next time the fibers are disconnected.
To minimize the effects of particulate contamination, the surface of the connector end must be
cleaned before connection. This cleaning operation is critical, as an improperly prepared optical
surface can cause loss of performance.
2.3.2 Optical Fiber Bend Radius
The Minimum Bend Radius (MBR) for optical fiber cables used on the S320 OCS is 1 inch (25 mm).
An optical fiber or fiber-optic cable should not be bent below the MBR. Bending a fiber below the
MBR can result in damage to the fiber. Improper handling of optical fiber and cables can have
detrimental effects on S320 OCS performance. Observe the following precautions for handling
fiber and cable:
Keep optical surfaces clean; only trained personnel should clean optical cables
and connectors.

S320 OCS Hardware User Guide
Doc. Part No. 460167-00
May 27, 2015
Rev. B7
Page 15 of 46
When optical cables or optical connectors are not connected, make sure the cables
and/or connectors are capped. Be sure to use clean caps.
Handle the fiber cables as little as possible.
Never eat, drink or smoke around optical equipment.
Keep cable runs neat and observe the MBR when bending fiber-optic cables.
2.4 Cleaning Substance Hazards
2.4.1 Isopropyl Alcohol
It may be necessary to use a solvent when cleaning optical fiber connectors. The recommended
solvent for cleaning optical fiber connectors is isopropyl alcohol (IPA) that is 99.8+% pure.
DOT Hazard Classification: Flammable Liquid
Always observe the following precautions when handling isopropyl alcohol:
Keep the container closed and away from heat, sparks or open flame.
Use with adequate ventilation.
Avoid breathing the vapor.
Avoid contact with eyes, skin and clothing.
Wash thoroughly after handling.
Store in an approved flammable materials cabinet when not in use.
Dispose of materials soiled with IPA in a clearly marked container approved for
such purpose.
If a spill occurs, clean up the spill and dispose of contaminated materials in
accordance with local requirements for hazardous waste.

S320 OCS Hardware User Guide
Doc. Part No. 460167-00
May 27, 2015
Rev. B7
Page 16 of 46
Isopropyl alcohol is harmful if it is inhaled, ingested or comes into contact with the
eyes or skin. Use it only in a well-ventilated area. If exposure occurs, immediately
call emergency medical services, followed by your local poison control center. For
external exposure (eyes or skin), immediately flush the exposed area with large
amounts of clean water for a minimum of 15 minutes.
2.4.2 Leakage and Spill Disposal
In the event of a leak or spill, remove all sources of ignition and ventilate the affected area.
Clean-up personnel require protective clothing and respiratory protection from vapors. Dispose
of contaminated clean-up materials only at an approved facility in accordance with local
requirements for hazardous waste.
2.4.3 Decanting
When decanting isopropyl alcohol from a distribution container to a supply container, make
sure the supply container is appropriately labeled to prevent possible contamination of the
alcohol with a foreign substance.
Perform the following steps when refilling storage and work containers:
1. Empty the current contents of the supply container into a solvent waste container.
2. Fill the empty supply container 5-10% full with isopropyl alcohol.
3. Cap the container and shake it to clean its interior.
4. Pour the shaken alcohol into the solvent waste container.
5. Refill the supply container 80-90% full.
6. Close the supply container lid.
7. Close the distribution container lid.

Doc. Part No. 460167-00
May 27, 2015
Rev. B7
Page 17 of 46
Failing to keep supply and distribution containers closed, except when in use, can
result in contamination of the IPA cleaning solution.
2.4.4 Nitrogen
CALIENT recommends using small, disposable cylinders of 99.9% pure compressed nitrogen gas
when cleaning S320 OCS optical fiber connectors. Attention should be given to the information
provided in the cylinder supplier’s Material Safety Data Sheet (MSDS).
Nitrogen cylinders contain gas under high pressure that can cause rapid suffocation
when released. Nitrogen gas acts as a simple asphyxiant by displacing air necessary
for life. If symptoms of asphyxiation occur—such as rapid respiration, loss of muscular
coordination, fatigue, dizziness or nausea—move immediately to fresh air. Also, never
puncture or incinerate nitrogen cylinders.
2.4.5 Nitrogen Cylinder Precautions
Be sure to observe the following precautions when using an industrial-size compressed nitrogen
gas cylinder:
Keep it from falling over or rolling around to avoid damaging the cylinder valve.
Open the valve a little at a time. If it cannot be opened by hand, return the cylinder to
the supplier. Never use force (e.g., a wrench) when opening or closing a cylinder valve.
Never heat a cylinder containing liquefied gas to increase the gas flow or the required
rate.
Only use connectors designed specifically for compressed-gas cylinders. Never use
intermediate connectors.
Always check the condition of couplings before use.

Use only materials compatible with the gas.
Never allow any substance (gas or liquid) to get into a cylinder that is in use. If there is
a risk this could happen, mount an anti-return valve. If a foreign substance accidentally
gets into a cylinder, notify the supplier immediately.

3THE CALIENT S320 OCS SYSTEM
3.1 Overview
CALIENT’s S320 OCS is at the leading edge of fiber-optic cross-connect systems. It provides
transparent, software-controlled fiber-optic switching functionality that will revolutionize the
way optical fiber is installed and managed.
The S320 OCS enables dynamic optical layer optimization in next-generation data centers and
software-defined networks (SDNs). Datacenter operators and service providers can leverage
the system’s high-bandwidth capability and flexibility to stay ahead of the runaway pace of
fiber deployment to make fiber networks more profitable.
The S320 OCS provides carrier-class reliability, making it suitable for Datacenters, Metro
Software-Defined Networks (SDN), FTTx networks and Government deployments. In addition,
the system supports a wide range of network applications—from the network core to access—
allowing any optical input fiber to be connected at the photonic level to any output fiber,
regardless of the data rate or protocol of the signals being carried by the fiber.
3.2 Architecture
The S320 OCS establishes, monitors and changes connections between single-mode optical
fibers using Micro-Electro-Mechanical Systems (MEMS) optical switching. Connections are
made between fibers carrying signals with any wavelength, data rate or protocol. The S320
architecture is shown in Figure 1.
The core of the S320 OCS is the MEMS Switch Module (MSM). Input fibers are connected to the
MSM, which establishes connections with any of the desired output fibers. Light tapped from
the input and output fibers is delivered to the Optical Monitoring Module (OMM) to enable
monitoring of existing connections and establishment and optimization of new connections.
Light is tapped using fiber tap couplers, and mirror drivers control each connection by supplying
voltage to each MEMS mirror. Users manage and communicate with the S320 OCS via the
Control Processor (CP). To ensure high availability, the CPs and power supplies are redundant.
