Connecting the Fiber Cable
To proceed with installation, connect the fiber optic cable to the transmitter
output. The optical output connector of the PWL 4100S is located on the rear
of the module, as shown in Figure 1-1 on page 1-2.
DANGER:
Invisible Laser Radiation.
AVOID EXPOSURE TO BEAM
.
Never operate unit with a broken fiber or with a fiber connector
disconnected.
To connect fiber optic cable to the transmitter output:
1. Verify that the transmitter module has been mounted into the HLP 4200
platform, as described in Section 2.2.
2. Determine the connector type on the PWL 4100S. The standard optical
connector recommended by Harmonic is SC/APC. Other connector types
can be special ordered.
3. Verify that the type of connector on the fiber cable is the same as what is
on the PWL 4100S, for example, SC/APC.
4. Verify that the fiber cable connector has been cleaned properly. If the fiber
cable connector needs to be cleaned, follow the cleaning procedure
outlined in Section
5.1.1 Cleaning Patch Cord or Pigtail Fiber Optical
5. Verify that the PWRLink II optical connector has not been exposed to any
contamination. If you suspect that the connector may have been exposed
to contamination (for example, by a dirty fiber cable connector), follow the
cleaning procedure outlined in Section
5.1.2 Cleaning Transmitter Module
NOTE:
Any contamination of either the fiber cable or PWL 4100S connector
can significantly degrade optical link performance. This degradation
will most likely manifest itself as poor carrier-to-noise (CNR)
performance.
6. For SC-type optical connectors, note the key characteristics of the mating
connectors and align them accordingly. Gently insert the fiber cable
connector into that of the PWL 4100S until the connector clicks into place.
For FC-type optical connectors, note the key characteristics of the mating
connectors and align them accordingly. Gently insert the fiber cable
connector into that of the PWL 4100S and tighten the rotating sleeve of the
connector.
Do not overtighten!
