Use only single-mode (SM) fiber cable with the 4-port OC-12/STM-4 ATM
FP. You must provide the cable with attached connectors.
The single-mode fiber cable must have a core diameter of 9 microns and
cladding diameter of 125 microns. The attenuation is less than 0.5 dB/km at
1300 nm.
The OC-12 uses standard duplex SC connectors.
The sum of cable splice 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.
The optical interface characteristics for the 4-port OC-12/STM-4 ATM
single-mode (SM) intermediate reach (IR) FP are shown in these tables
