... 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 ...

... The fault isolation feature allows a host to quickly pin- point the location of a link failure, minimizing downtime. For optical links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speed- ing service of an installation. AFBR-700SDZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power can be used to assess local transceiver current operating conditions. In addition, status flags TX_DIS- ABLE and Rx Loss of Signal (LOS) are mirrored in memory and available via the two-wire serial interface ...

... IC which uses the incoming differential high speed logic signal to modulate the laser diode driver current. This Tx laser driver circuit regulates the optical power at a con- stant level provided the incoming data pattern is DC bal- anced. Transmit Disable (TX_DISABLE) The AFBR-700SDZ accepts an LVTTL compatible trans- mit disable control signal input which shuts down the transmitter optical output. A high signal implements this function while a low signal allows normal transceiver op- eration. In the event of a fault (e.g. eye safety circuit ac- tivated), cycling this control signal resets the module as depicted in Figure 6. An internal pull up resistor disables the transceiver transmitter until the host pulls the input low ...

... The AFBR-700SDZ interfaces with the host circuit board through the twenty contact SFP+ electrical connector. See Table 2 for contact descriptions. The module edge connector is shown in Figure 4. The host board layout for this interface is depicted in Figure 8. The AFBR-700SDZ high speed transmit and receive in- terfaces require SFF-8431 compliant signal lines on the host board. To simplify board requirements, biasing re- sistors and AC coupling capacitors are incorporated into the SFP+ transceiver module (per SFF-8431) and hence are not required on the host board. The TX_DISABLE, TX_FAULT and RX_LOS signals require LVTTL signals on the host board (per SFF-8431) if used ...
