1. General Information
1.1. Introduction
This manual contains information on the installation and operation of the TWL-
P-HS High Speed Tunable Wavelength Laser demonstration purposes.
1.2. Product Overview
The TWL-P-HS is a high speed, innovative, all-in-one tunable and
programmable laser source with high spectral purity. Based on laser crystal
technology, the TWL-P-HS can operate in three distinct modes: CW mode,
continuous scan mode, and programmable scan mode over the entire C-band
range. It also features variable scan speed up to 4000 nm/s. Its lightweight and
compact design allow it to be easily utilized both in laboratory and field
engineering applications. A built-in 7” touchscreen with intuitive graphical
interface gives the user full control over the operation of the device. In addition,
the TWL-P-HS can be controlled via remote software through USB or Wi-Fi. Its
polarization output and high wavelength and power stability make it a perfect
solution for a seed laser for optical modulation and other test and measurement
applications.
1.3. User Safety
1. The TWL-P-HS unit emits high intensity invisible light from the optical output
receptacle. Avoid direct exposure to skin and eyes.
2. The user should never open the equipment case; any attempt will void the
warranty and may result in electric shock and EMS attack to equipment in the
vicinity. If requesting to open up the unit for demonstration purposes, please
contact Optilab prior to doing so.
3. The user should avoid using any solvent or vaporizing chemical to clean the
equipment panel or case. It may result in damage to the surface and internal
circuits.

2. Operation
2.1. Introduction
This chapter describes how to operate the TWL-P-HS, and discusses the
location and function of the controls and connectors.
2.2. Initial Inspection
Your TWL-P-HS was carefully inspected before it left the manufacturer. It should
be in proper working order upon receipt. You should, however, inspect the unit
for any damage that may have occurred in transit. If the shipping container or
the packing material is damaged, keep it until the contents of the shipment have
been checked to be free of mechanical and electrical damages. Notify Optilab,
LLC promptly if any notable damage is found.
The TWL-P-HS shipment should include the following:
- TWL-P-HS device
- Power Supply

4. Troubleshooting
SYMPTOM
POSSIBLE CAUSE AND SOLUTION
OPTICAL OUTPUT POWER
FROM TRANSMITTER NOT
HIGH ENOUGH.
C: Optical output connector is dirty.
S: Disable optical output and clean optical connectors.
C: Use of incorrect optical adapter or connector.
S: Use only the indicated optical adapter and connector. If
measurement instruments accept different connector type, then
use a hybrid patchcord.
C: Optical output connector damaged.
S: Measure optical output power with power meter and compare
with original test data. Return to Optilab for repair if the
difference is high (>4 dB) and cannot be corrected by cleaning
or replacing the optical connectors. Always apply dust cover
plugs to unused optical receptacles to prevent the damage of
internal optical connectors.
UNIT DOES NOT POWER
UP.
C: Insufficient electrical voltage.
S: Check that the electrical supply is 110/220 VAC.
C: Power cord is loose.
S: Plug power cord is firmly into the unit.
UNIT RESETS OR BLINKS
ON AND OFF
C: Insufficient electrical voltage.
S: Check that the electrical supply is at least 110/220 VAC.

5.3. Care of Fiber-optic Connectors
Damage to optical connectors account for more than 70 percent of equipment
performance degradation. To avoid such damage, the user should use only industrial
grade 99% pure isopropyl alcohol and follow the procedures below to keep the
connectors, adaptors and receptacles clean.
Cleaning Optical Connector End-face with Wipe and Alcohol
To properly clean optical connectors utilizing lens tissue grade wipes and alcohol
follow the procedure below. The moist wipe removes dust particles, oil and
contaminants that may damage or blot the end-face of the connector during
connection. The dry wipe removes residual alcohol that may be ignited by optical
emission.
1. Disable the optical output and turn off unit to prevent accidental exposure or
damage to the optical connector by optical emission.
2. Moisten a wipe with alcohol by placing on top of the alcohol dispenser and push
down to saturate the wipe.
3. Place the moist wipe on a work surface, and place a second dry wipe next to it.
4. Wipe the optical connector, end-face down on the moist wipe 3 times and then
repeat on the dry wipe.
5. Visually inspect the end-face of the optical connector with an optical microscope to
verify cleanliness. Repeat steps 2 to 5 as needed.
Cleaning Optical Connector Sides, Receptacles, Adaptors with Swab and Alcohol
Dust or particles can adhere to the insides of receptacles and adaptors or the sides of
the optical connector ferrule. Their presence can affect the alignment of the optical
fiber connectors and increase connection loss. To properly clean optical connectors,
receptacles, and adaptors utilizing a swab and alcohol follow the procedure below:
1. Disable the optical output and turn off unit to prevent accidental exposure or
damage to the optical connector by optical emission.
2. Moisten the swab by placing it on top of the alcohol dispenser and push down to
saturate the swab.
3. For receptacles, adapters, or other connection points, insert the moistened swab
and rotate the tip 1/2 turn clockwise and counter-clockwise 6 times while applying
light but firm pressure.
4. For fiber connectors, rotate the tip of the moistened swab 5 revolutions around the
connector while applying light but firm pressure.
5. Visually inspect the end face of the connector with an optical microscope to verify
cleanliness. Clean end-face as needed.
