A.9.1 TXP_MR_10G Card Specifications
Caution 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.
– Connectors: LC
– Compliance Telcordia GR-253-CORE, ITU-T G.707, ITU-T G.691
• Transmitter (trunk side)
– Maximum transmitter output power: +3.5 dBm
– Minimum transmitter output power: +2.5 dBm
– Transmitter: Lithium Niobate (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_10G (16 card versions, each covering
two wavelengths):
– 1530.33 to 1531.12 nm (two wavelengths)
– 1531.90 to 1532.68 nm (two wavelengths)
– 1534.25 to 1535.04 nm (two wavelengths)
– 1535.82 to 1536.61 nm (two wavelengths)
– 1538.19 to 1538.98 nm (two wavelengths)
– 1539.77 to 1540.56 nm (two wavelengths)
– 1542.14 to 1542.94 nm (two wavelengths)
– 1543.73 to 1544.53 nm (two wavelengths)
– 1546.12 to 1546.92 nm (two wavelengths)
– 1547.72 to 1548.51 nm (two wavelengths)
– 1550.12 to 1550.92 nm (two wavelengths)
– 1551.72 to 1552.52 nm (two wavelengths)
– 1554.13 to 1554.94 nm (two wavelengths)
– 1555.75 to 1556.55 nm (two wavelengths)
– 1558.17 to 1558.98 nm (two wavelengths)
– 1559.79 to 1560.61 nm (two wavelengths)
• Receiver (trunk side):
– Receiver input power (no FEC, unamplified, 23 dB optical signal-to-noise ratio [OSNR], BER
1 * 10 exp – 12): –8 to –21 dBm
– Receiver input power (no FEC, unamplified, 23 dB OSNR, at +/– 1000 ps/nm BER 1 * 10
exp – 12): –8 to –19 dBm
– Receiver input power (no FEC, amplified, 19 dB OSNR, BER 1 * 10 exp – 12): –8 to –20 dBm
