        AFBR-700SDZ 10Gb Ethernet, 850 nm, 10GBASE-SR, SFP+ Transceiver

        性能描述：

        The Avago AFBR-700SDZ transceiver is part of a family of SFP+ products. This transceiver utilizes Avago’s 850nm VCSEL and PIN Detector technology to provide an IEEE 10Gb Ethernet design compliant with the 10GBASE-SR standard. The AFBR-700SDZ transceiver is designed to enable 10Gb Ethernet equipment designs with very high port density based on the new electrical and mechani¬cal specification enhancements to the well known SFP specifications developed by the SFF Committee. These specifications are referred to as SFP+ to recognize these enhancements to previous SFP specifications used for lower speed products. Avago Technologies is a an active participant in the SFF Committee specification develop¬ment activities. 

        Avago’s AFBR-700SDZ optical transceiver supports high-speed serial links over multimode optical fiber at signal¬ing rates up to 10.313 GBd. The AFBR-700SDZ is compliant with SFF-8431 Specifica¬tions for Enhanced 8.5 and 10 Gigabit Small Form Factor Pluggable Module “SFP+” and SFF-8472 Specification for Diagnostic Monitoring Interface for Optical Transceivers. Real time temperature, supply voltage, laser bias current, laser average output power and received input power information is provided with the two-wire interface de¬fined in SFF-8472. This information is in addition to con¬ventional SFP base data. The digital diagnostic interface also adds the ability to disable the transmitter (TX_DIS¬ABLE), monitor for Transmitter Faults (TX_FAULT), and monitor for Receiver Loss of Signal (RX_LOS).

        主要特性：
        Avago 850nm VCSEL source and Transmitter Optical Subassembly technology
