... The digital diagnostic interface also adds the ability to disable the transmitter (TX_DISABLE), monitor for Trans- mitter Faults (TX_FAULT), and monitor for Receiver Loss of Signal (RX_LOS). Installation The AFBR-57M5APZ can be installed in any SFF-8074i compliant Small Form Pluggable (SFP) port regardless of host equipment operating status. The AFBR-57M5APZ is hot-pluggable, allowing the module to be installed while the host system is operating and on-line. Upon insertion, the transceiver housing makes initial contact with the host board SFP cage, mitigating potential damage due to Electro-Static Discharge (ESD) ...

... The TX_FAULT will be latched high when a laser fault occurs and is cleared by toggling the TX_DISABLE input or power cycling the transceiver. The transmitter fault condition can also be monitored via the two-wire serial interface (address A2, byte 110, bit 2). Eye Safety Circuit The AFBR-57M5APZ provides Class 1 (single fault tolerant) eye safety by design and has been tested for compliance with the requirements listed in Table 1. The eye safety circuit continuously monitors the optical output power level and will disable the transmitter upon detecting an unsafe condition beyond the scope of Class 1 certifica- tion. Such unsafe conditions can be due to inputs from the host board (Vcc fluctuation, unbalanced code fault within the transceiver ...

... Rx_LOS thresholds are factory set so that a high output indicates a definite optical fault has occurred. Rx_LOS can also be monitored via the two-wire serial interface (address A2h, byte 110, bit 1). Functional Data I/O The AFBR-57M5APZ interfaces with the host circuit board through twenty I/O pins (SFP electrical connector) identified by function in Table 2. The board layout for this interface is depicted in Figure 6. The AFBR-57M5APZ high speed transmit and receive interfaces require SFP MSA compliant signal lines on the host board ...

... Electromagnetic Interference (EMI) Equipment incorporating gigabit transceivers is typically subject to regulation by the FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. The AFBR-57M5APZ’s compliance to these standards is detailed in Table 1. The metal housing and shielded design of the AFBR-57M5APZ minimizes the EMI challenge facing the equipment designer. EMI Immunity (Susceptibility) Due to its shielded design, the EMI immunity of the AFBR- 57M5APZ exceeds typical industry standards ...
