Figure 14-51

You must use a 15-dB fiber attenuator (10 to 20 dB) when working with the TXP_MR_10G card in a

loopback on the trunk port. Do not use direct fiber loopbacks with the TXP_MR_10G card. Using direct

fiber loopbacks causes irreparable damage to the TXP_MR_10G card.

You can install TXP_MR_10G cards in Slots 1 to 6 and 12 to 17. You can provision this card in a linear

configuration. TXP_MR_10G cards cannot be provisioned as a BLSR, a path protection, or a

regenerator. They can be used in the middle of BLSR or 1+1 spans. They can only be used in the middle

of BLSR and 1+1 spans when the card is configured for transparent termination mode.

The TXP_MR_10G port features a 1550-nm laser for the trunk port and a 1310-nm laser for the for the

client port and contains two transmit and receive connector pairs (labeled) on the card faceplate.

The TXP_MR_10G card detects SF, LOS, or LOF conditions on the optical facility. Refer to the

Cisco ONS 15454 SONET and DWDM Troubleshooting Guide for a description of these conditions. The

card also counts section and line bit interleaved parity (BIP) errors from B1 and B2 byte registers in the

section and line overhead.
