Equipping rules

The OC-192 DWDM G.709 FEC circuit pack are equipped in slots 11 and 12 of the OPTera Metro shelf. See Table 3-3 on page 3-6for operational temperature ranges.

Note 1: Requires the shelf to be equipped with STX-192 circuit packs in slots 13 and 14.

Note 2: Interoperability with the OPTera Metro 3500 OC-192 Long reach (LR) G.709 FEC and OC-192 DWDM G.709 FEC optical interfaces requires G.709 compatible optics. You can equip the OPTera Metro 3500 shelf with a mix OC-192 IR and OC-192 G.709 circuits, however they must connect to the same type of card on the other end of the fiber span.

OC-48 optical interface circuit pack (NTN440BA, DA, FA, EA, EH, BH)

The main transport OC-48 circuit pack operates at an OC-48 line rate

(2488 Mbit/s). The OC-48 circuit pack can be installed in slots 11 and 12 in a UPSR, 1+1 linear system and BLSR. In the 1+1 linear protection scheme, OC-48 circuit packs can be provisioned in either unidirectional or bidirectional mode. See Table 3-3 on page 3-6for operational temperature ranges.

See Table 3-9for the OC-48 optical wavelengths that are supported for the transmit and receive optical circuit packs.

STS-1 path trace for OC-48

OPTera Metro 3500 supports path trace capability for OC-48 services. Path trace is a 64 byte ASCII string that can be provisioned by the user. Path trace is transmitted through the J1 byte of the STS Path Overhead. It can be used by STS path terminating equipment (PTE) to verify its continued connection to the intended transmitting STS PTE.
