Radiance Multi-Rate Line Card 15
• The port’s receiver detects the presence of optical power and
the port’s CDR circuitry has locked onto the incoming signal.
For information on replacing the SFP transceiver, refer to Changing the
SFP Optics.
BWDM Interface
The bidirectional wavelength division multiplexed (BWDM) trans-
ceiver provides one singlemode SC connector. The O311-10-xx
supports a maximum segment length of 10 km; the O383-20-xx
supports a maximum segment length of 20 km. BWDM transceivers
must always be used in complementary pairs. That is, the O311-10-31
must be connected to the O311-10-49, and the O383-20-31 must be
connected to the O383-20-55.
The O311-10-31 transmits data at a wavelength of 1310 nm and
receives at 1490 nm. Correspondingly, the O311-10-49 transmits at
1490 nm and receives at 1310 nm. The O383-20-31 transmits at 1310
nm and receives at 1550 nm; the O383-20-55 transmits at 1550 nm and
receives at 1310 nm.
