Install optical PTMs

This section contains the instructions to install optical PTMs in the VLNC50. VLNC52

and VLNC64 circuit packs

Refer to the engineering job specification. Identify the proper circuit pack type (VLNC50,

VLNC52 or VLNC64) and the port socket being equipped with the optical pluggable

transmission module (PTM). Verify the PTM for the VLNC50/VLNC52 optical rate and

reach matches the rate and reach of the PTM. Verify the PTM for the VLNC64 (matches

the rate and reach of the PTM. See

Note:

optical ports to maintain cleanliness during storage and/or transportation. It is

recommended that the dust plug be kept in place to maintain cleanliness until the

optical fiber is connected. With proper care and handling, cleaning the pluggable

optics modules should not be necessary.

Check the ports for cleanliness and clean the pluggable optics module if necessary. See

Appendix B, "Fiber

Note:

used on the receive (RX) port. The receive port contains a lens for focusing a wide

input. The lens is more easily scratched than cleaned.

Insert the pluggable optics modules in the required socket of the circuit pack faceplates,

then wiggle the optics module to verify that it is locked in the socket. See

"PTM

Repeat Step 1 through Step 3 if more optical modules need to be installed.

Check off appropriate box in
