GigaBit Fiber Media Converter

Introduction
Net Optics GigaBit SX/TX and LX/TX Converters are simple and reliable
devices for connecting GigaBit copper trafc and GigaBit ber devices and
links. Use these bi-directional media converters individually to connect Giga-
Bit copper and GigaBit ber devices, or in pairs at each end of long-distance
ber links. These Converters are the perfect solution for dispersed networks
where media conversion required between copper network segments separated
by long distances.
Fast and Versatile
The GigaBit SX/TX and LX/TX Converters support seamless media conver-
sion of optical signals for data rates at 1000 Mbps, over a full link distance of
220 meters (62.5/125µm multimode ber), 550 meters (50/125µm multimode
ber) or 10 kilometers (8.5/125µm singlemode ber). The CV-SX/GCU
model supports transmission over either 62.5µm or 50µm multimode ber.
The Converter supports either full or half-duplex transmission with optional
auto-negotiation over the ber link and UTP port.
Fault Tolerant and Reliable
Net Optics GigaBit SX/TX and LX/TX Converters incorporate Link Fault
Signaling, which gives the devices connected to the Converter critical in-
formation about link status. If either side of the bi-directional link fails, the
Converter immediately communicates the fault to both devices, reducing the
time required to activate a redundant path. To control jitter over long optical
links, the Converter features Clock and Data Recovery (CDR). CDR ensures
that the overall jitter budget is not exceeded when deploying converter pairs
with long ber links.
For extra uptime protection, Net Optics Converters offer redundant power
connections. Should the primary power source fail, the Converter automati-
cally switches to the backup power source.

Support
Net Optics offers free technical support throughout the lifetime of your
purchase. Our technical support team is available from 8 am to 5 pm Pacic
Time, Monday through Friday at [phone] and via email at
[email protected]. FAQs are also available on Net Optics website
at www.netoptics.com.
Auto-negotiation Notes
1. The CV-SX/GCU and CV-LX/GCU units enable optional auto-negotiation
over the connected ber link in conjunction with the existing UTP port
auto-negotiation. The control switch is located at the side of the unit.
2. When the Fiber Port Negotiation function is turned-on [the default posi-
tion], it allows the MAC [media access control] behind the other connected
device's ber port to "see" the converter's copper port auto-negotiation
with its link partner and participate in the end-to-end negotiation process.
This will tend to eliminate opposite ends of a series of copper/ber seg-
ments negotiating/defaulting to different service levels.
3. When the Fiber Port Negotiation function is turned-off, standard cop-
per port, auto-negotiaion between the converter and the other connected
devices is allowed. The converter's ber port will transparently forward all
trafc. This is appropriate when the converter is connected to older equip-
ment without ber auto-negotiation present or turned-on.

Connecting the GigaBit Media Converter to the Network
Connecting the GigaBit Fiber Port to the Network:
1. Unpack the GigaBit Media Converter, verify that you have all components,
and obtain the required cables needed to successfully install the unit.
2. Using a duplex SC cable, connect the appropriate switch, server, or router
to the GigaBit Media Converter's ber port.
The use of singlemode or multimode cabling is determined by the GigaBit
media Converter model purchased.
Note:________________________________________________________________
For connections with legacy devices, where Fiber Port negotiation is not pres-
ent, it will be necessary to disable the toggle switch (FPN) on the side of the
unit and power cycle the tap.
______________________________________________________________________
Multimode 1000BaseSX ports on CV-SX/GCU Series converters are
connected via standard 50/125µm, 62.5/125µm or 100/140µm multimode
ber. Singlemode 1000BaseLX ports are connected by 8.5µm singlemode
ber. Singlemode 1000BaseLX ports also may be used to increase the
transmission distance over multimode ber cable.
When installing the GigaBit Media Converter, care must be taken in choos-
ing the appropriate cabling to avoid Differential Mode Delay (DMD) effects.
DMD is caused by singlemode, (1310 nanometer) laser point sources launch-
ing into multimode cable. Optical power is concentrated in the center of the
ber core, propagating in less than 5% of possible modal paths. This can
result in reduced bandwidth and/or the appearance of individual data pulses,
refracting into multiple, overlapping light pulses at the receiver end, therefore
causing CRC errors.
The connection requires a Mode Conditioning patch cable to provide the
Conditioned Launch necessary to prevent (DMD) effects. Mode Condition-
ing patch cables are not used with short wave length (850 nano-meter) lasers.
Note that ber cable is typically certied for a particular bandwidth using light
emitting diodes (LEDs) that provide the “Overlled Launch” condition i.e.
illuminate all possible modes and bers.
For additional details see the Restricted Launch Specication dened by the
Telecommunications Industry Association. The TIA FO-2.2.1 Committee has
released two standards: (1) FOTP-203: Launched Power Distribution Mea-
surement Procedure for Graded-Index Multimode Fiber Transmitters, and (2)
FOTP-204: Measurement of Bandwidth on Multimode Fiber.

Connecting the GigaBit Media Converter to the Network
Connecting the GigaBit Copper Port to the Network
1. Using a CAT5e cable, connect the appropriate switch, server to the GigaBit
Media Converter's copper port.
2. Supply power to the GigaBit Media Converter using the two power sup-
plies included with the unit.
3. Compare the LEDs on the Media Converter to the information below to
verify correct setup.
PWR: Power. Main/Redundant power LED illuminates green when device
is powered on (Located on rear of unit).
F/O Link: Illuminates green when a good ber optic link is established
UTP Link: Illuminates green when a good UTP link is established.
F/O ACT: Illuminates green when activity on the ber optic link is estab-
lished.
UTP ACT: Illuminates green when activity on the UTP link is established.
FPN: Illuminates green when ber auto-negotiation switch is set to an on
position.
FD: Illuminates green when full duplex trafc is present.
Note: _______________________________________________________________
The CV-SX/GCU converter detects the incoming signal and
automatically makes the correct MDI (straight) or MDI-X (crossover)
conguration selection. Cable/connector conicts can be ignored.
When lit, the 100 TX LED only shows that a 100BaseT source
has been connected to the GigaBit UTP port. Although showing a link,
the connection will be non-functional. A 100BaseT (100Mbs) data stream
is too slow for the GigaBit ber-optic driver circuit to process. Net Optics
GigaBit Media Converters only operate successfully at GigaBit data rates.

Safety Notes on Laser Singlemode and Multimode-type
Connectors
The CV-LX/GCU uses (invisible) 1310 nm wavelength, eye-safe type, laser,
singlemode connectors.
The CV-SX/GCU uses (visible) 850 nm wave length, eye-safe type, laser
multimode connectors.
Observe caution when deploying equipment using laser optics. Non-eye safe
laser devices may be inadvertently connected to cabling that is intended to be
attached to eye-safe 850 nm or 1300 nm laser driven equipment. This poses
a risk for eye and equipment damage. All ber optic cables (connectors) that
are or may be connected to a laser source should be clearly labeled and as-
sumed to be connected to non-eye safe laser optics.
Note: _______________________________________________________________
Do not connect non-eye safe laser devices to eye-safe class equipment. Non-
eye safe laser driven devices, besides damaging eye sight, can permanently
damage eye-safe (low-power laser) rated equipment. Such damage will not
be covered by warranty. Net Optics, Inc. disclaims all liability for damages
arising from mis-use or incorrect installation of laser driven equipment.
______________________________________________________________________
CAUTION: NEVER ATTEMPT TO VERIFY ANY FIBER OPTIC
CONNECTION BY LOOKING DIRECTLY INTO A FIBER-OPTIC PORT
OR CABLE. IF THE LIGHT SOURCE IS A NON-EYE SAFE, LASER
EMITTER, PERMANENT EYE DAMAGE MAY RESULT.
NEVER LOOK INTO THE BORE OF A FIBER OPTIC CONNECTOR!
