Vsp3-O Fp Cable Assembly - Nortel Passport 15000 Hardware Description

The VSP3-o FP card can receive IP-routed traffic over the backplane from a
4-port gigabit Ethernet FP card or an ATM IP FP card in the same Passport
shelf, and send the traffic to the TDM network through the active port 0 of the
two OC-3/STM-1 optical TDM ports on the VSP3-o FP card. TDM signals
can arrive on the active port 0 of the two OC-3/STM-1 optical TDM ports on
the VSP3-o FP card, and leave through the 4-port gigabit Ethernet FP card to
the IP network.

VSP3-o FP cable assembly

Use only single-mode (SM) fiber cable with the VSP3-o FP card. You must
provide the cable with attached connectors.
Single-mode fiber cable must have a core diameter of 9 microns and a
cladding diameter of 125 microns. The attenuation is less than 0.5 dB/km at
1300 nm.
The VSP3-o FP card uses standard duplex LC connectors.
The sum of cable losses and connector losses from the FP to customer
premises equipment (CPE) must not exceed 12 dB for single-mode cable. The
losses in a transmission path determine the distance the FP can send a signal.
The maximum distance from the FP to CPE is 15 to 20 km for single-mode
cable, depending on the losses due to splices and connectors.
