The fiber mode type must be the same as the FP mode type. You must provide
the cable with attached connectors. Use single-mode (SM) fiber cable with
single-mode FPs and multimode (MM) fiber cable with multimode FPs.
Multimode fiber cable must conform to ANSI/E1A/T1A-568. The multimode
fibre cable must have a core diameter of 62.5 microns and a cladding diameter
of 125 microns. The modal bandwidth is at least 500 MHz-km and the
attenuation is less than 1.0 dB/km at 1300 nm.
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 OC-3 uses standard duplex SC connectors.
The sum of cable losses and connector losses from the FP to customer
premises equipment (CPE) must not exceed 10 dB for multimode cable and
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 2 km for multimode cable and 15 to 20 km for single-mode cable,
depending on the losses due to splices and connectors.
