Руководство По Установке для Cisco Cisco ONS 15454 M12 Multiservice Transport Platform (MSTP)

 lists the four port-level LEDs on the TXP_MR_10E_C and TXP_MR_10E_L cards.

The TXP_MR_10E_C card has the following specifications:

Line (trunk side) 

Bit rate: OC-192/STM-64 (9.95328 Gbps), OTU2 (10.70923 Gbps), 10GE (10.3125 Gbps), 
10GE into OTU2 (non-standard 10.0957 Gbps), 10G FC (10.51875 Gbps), or 10G FC into 
OTU2 (non-standard 11.31764 Gbps)

Code: Scrambled NRZ 

Fiber: 1550-nm single-mode

Maximum chromatic dispersion allowance: +/– 1200 ps/nm (specified penalty) 

Loopback modes: Terminal and facility

You must use a 15-dB fiber attenuator (10 to 20 dB) when working with the TXP_MR_10E_C 
card in a loopback on the trunk port. Do not use direct fiber loopbacks with the 
TXP_MR_10E_C card. Using direct fiber loopbacks causes irreparable damage to the 
TXP_MR_10E_C card.

Connectors: LC 

Compliance: Telcordia GR-253-CORE, ITU-T G.707, ITU-T G.957, and ITU-T G.709 

Transmitter (trunk side) 

Maximum transmitter output power: +6 dBm

Minimum transmitter output power: +3 dBm

Transmitter: LN external modulator transmitter

Wavelength stability (drift): +/– 25 picometers (pm)

An optical device on the card keeps the laser wavelength locked as closely as possible to the ITU nominal 
value. The allowed drift is +/– 25 pm.

Receiver (trunk side)

Green Client LED

The green Client LED indicates that the client port is in service and that it is 
receiving a recognized signal. 

Green DWDM LED

The green DWDM LED indicates that the DWDM port is in service and that 
it is receiving a recognized signal.
