Appendix B Hardware Specifications
B.5.6 TXP_MR_10E Card Specifications
–
Depth with backplane connector: 9.250 in. (235 mm)
–
Weight not including clam shell: 3.1 lb (1.3 kg)
B.5.6 TXP_MR_10E Card Specifications
The TXP_MR_10E 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 11.0957 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
Caution
You must use a 15-dB fiber attenuator (10 to 20 dB) when working with the TXP_MR_10E
card in a loopback on the trunk port. Do not use direct fiber loopbacks with the TXP_MR_10E
card. Using direct fiber loopbacks causes irreparable damage to the TXP_MR_10E 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 for C-band and +2 dBm for L-band
–
Transmitter: LN external modulator transmitter
–
Wavelength stability (drift): +/– 25 picometers (pm)
Note
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.
•
Currently available wavelengths and versions of TXP_MR_10E:
C-band frequency plan (eight card versions, each with four tunable channels on the ITU 100-GHz
grid):
–
1530.33 to 1533.07 nm (four channels)
–
1534.25 to 1537.00 nm (four channels)
–
1538.19 to 1540.95 nm (four channels)
–
1542.14 to 1544.92 nm (four channels)
–
1546.12 to 1548.92 nm (four channels)
–
1550.12 to 1552.93 nm (four channels)
–
1554.13 to 1556.96 nm (four channels)
