OPTICAL CONNECTORS AND CLEANING
The standard optical connector provided with the 7-OR-RT is an SC/APC with an 8° angle. No tools are required for
connection to/from this type of optical connector. The fiber ends can be damaged by the insertion of contaminated
connectors into a bulkhead or receptacle, or by the insertion of a clean connector into a dirty bulkhead. Fiber connectors
should never be left uncovered. Optical connectors should be cleaned before usage.
Warning: When powered, optical transmitters generate invisible, high-energy laser beams.
Even when the transmitter is not powered, laser beams may be present in the incoming
cable. Although you can’t see them, these beams can cause tissue injury, including permanent
eye damage. Whenever the optical cable is disconnected from the receiver or patch panel,
avoid direct contact with the end of the cable. Be absolutely certain the optical equipment
at both ends of the cable is powered off before attempting to clean connectors.
1. Power off the optical equipment at either end of the optical cable designated for cleaning. Verify the power is off by
checking the power indicator LEDs.
2. If the connector is plugged into an adapter or bulkhead, unplug it and cover the connector with a clean cap.
3. If there’s a cover on the adapter or bulkhead, remove it. Spray the inside of the adapter or bulkhead with compressed
air, using a can of compressed air equipped with an extension tube.
4. Clean the bulkhead or adapter by flushing it with 90% isopropyl alcohol without additives or using a stick-type
cleaner. Let the alcohol dry.
5. Remove the protective cap from the connector, then spray the connector face with compressed air.
6. Next, clean the connector face using a lint-free tissue moistened with 90% isopropyl alcohol without additives.
Carefully clean the connector face.
7. Once you have finished cleaning the connector, align the connector key with the slot in the bulkhead or adapter, and
install the connector into place.
EXTERNAL TEST POINTS
The 7-OR-RT has three external test points. The first is for optical power output calibrated at 1V/mW. It should be
monitored with a high impedance voltmeter. This test point is for long term monitoring purposes. The optical output power
should be measured using an optical power meter at the time of installation. The second is an RF test port for monitoring
the RF drive level to the laser. The nominal drive level is +8dBmV per channel with 6 channel loading. Consult the
checklist for the exact value. The third is a test point for laser bias current calibrated at 20mV/mA. It should be
monitored with a high impedance voltmeter. This test point is for long term monitoring purposes.
