A.9.14 GE_XP and 10GE_XP Card Specifications
• Transmitter (trunk side)
–
Maximum transmitter output power: +3 dBm
–
Minimum transmitter output power: -1 dBm

Link loss budget: 24 dB minimum, with no dispersion or 22 dB optical path loss at
BER = 1 * 10 exp – 12 including dispersion
• Line (client side)
–
Bit rate: 1.125Gbps (GE) or 10.3125Gbps (10GE)
–
Code: Scrambled NRZ
–
Fiber: 1310-nm single-mode or 850-nm multimode
–
Maximum chromatic dispersion allowance: 12 ps/nm (SR SFP version)
–
Loopback modes: Terminal and facility
–
Connectors: LC (optical)
• Transmitter (client side): Depends on the SFP that is used.
• Receiver (client side): Depends on the SFP that is used.
