Appendix B Pluggable Transceiver Modules WDM Transceivers Table B-16 lists the fiber loss budgets for the 10-GB X2 transceivers. Table B-16 X2 Transceiver Optical Transmit and Receive Specifications X2 Transceiver Product Number Transmit Power (dBm) Receive Power (dBm) X2-10GB-LRM 0.5 (max) -6.5 (min) 0.5 (max) -8.4 (min) (In average)1 X2-10GB-SR -1.2 (max)2 -6.4 (min) (in Optical Modulation Amplitude (OMA)) -1.0 (max) -7.3 (min) -9.9 (min) X2-10GB-LR 0.5 (max) 0.5 (max) -8.2 (min) -14.4 (min) X2-10GB-ER 4.0 (max) -1.0 (max) -4.7 (min) -15.8 (min) X2-10GB-LX4 -0.5 per lane (max) -0.5 (max) -6.75 per lane -14.4 per lane 1. Both the average and the OMA specifications must be met simultaneously. 2. The launch power shall be the lesser of the class 1 safety limit or the maximum receive power. Class 1 laser requirements are defined by IEC 60825: 2001. Table B-17 lists the physical and environmental specifications for the X2 transceiver. Table B-17 10-GB X2 Transceiver Physical and Environmental Specifications Item Dimensions (H x W x D) Operating temperature Storage temperature Specification 0.53 x 1.41 x 3.58 in. (13.46 x 36 x 91 mm) 32° to 104°F (0° to 40°C) -40° to 167°F (-40° to 75°C) WDM Transceivers The WDM transceiver modules are listed in Table B-18 along with brief descriptions of the transceiver modules and illustration references.
