LC,
duplex 4-port GigE,
OC-3,
STM-1,
VSP3 Align the pair of ridges on the connectors with the pair of keyways on
the optical transceiver. Gently and smoothly push the connector in until
feeling very slight resistance up to the tab clicking.
With SFP optical modules, the bale latch must be closed against the
body of the module before plugging in the connector. The latch
prevents removing the SFP without first disconnecting the LC cables.
See the figure “A typical SFP optical module” (page 590).
With NTHW24 or NTHW31 FPs, the transmit (Tx) is oriented above the
receive (Rx) for ports 0-7 and below the Rx for ports 8-15. The two
columns of ports also have opposite keyway orientations, and the P is
omitted from port numbers 10 to 15. See the figure “The transmit and
receive orientation on a 16-port OC-3/STM-1 FP (NTHW31)”
(page 327).
With NTHW44 FPs, the transmit (Tx) is oriented to the left of the
receive (Rx) on each transceiver. See the figure “The transmit and
receive orientation on a 16-port OC-3/STM-1 POS and ATM FP
(NTHW44)” (page 328).
With NTHW49 and NTHW84 FPs, the transmit (Tx) is oriented below
the receive (Rx) on the transceiver. See the figures of the faceplates in

LC,
simplex 4-port GigE,
OC-3,
STM-1 Align the ridge on the connector with the keyway on the optical
transceiver. Gently and smoothly push the connector in until the tab
clicks.
MT-RJ OC-3,
STM-1,
16-port Align the ridge on the connector with the keyway on the faceplate.
Gently and smoothly push the connector in until you feel the tab
engage or hear it click.
The Tx and Rx pairs have opposed keyway orientations on each side
of the faceplate, and the P is committed from port numbers 10 to 15.
See the figure “The transmit and receive orientation on a 16-port OC-3/
STM-1 FP (NTHW21)” (page 326).
SC,
simplex or
duplex OC-n,
STM-n Align the ridge on each connector with each keyway on the faceplate.
Gently and smoothly push the connector in until the tab or tabs click.
