Conventional EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with INF-8074. New digital diagnostic information, bytes 0-255 at memory address 0xA2, is compliant to SFF-8472. The new diagnostic information provides the opportunity for Predictive Failure Identification, Compliance Prediction, Fault Isolation and Component Monitoring. Transmitter Section The transmitter section includes consists of the Transmitter Optical SubAssembly TOSA and laser driver circuitry. The TOSA, containing an 850nm VCSEL Vertical Cavity Surface Emitting Laser light source, is located at the optical interface and mates with the LC optical connector. The TOSA is driven by a custom 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 constant level provided the incoming data pattern is dc balanced 8B/10B code, for example . Transmit Disable Tx_Disable The AFBR-57J7APZ accepts a TTL and CMOS compatible transmit disable control signal input pin 3 which shuts down the transmitter optical output. A high signal implements this function while a low signal allows normal transceiver operation. In the event of a fault e.g. eye safety circuit activated , cycling this control signal resets the module as depicted in Figure An internal pull up resistor disables the transceiver transmitter until the host pulls the input low. Host systems should allow a 10ms interval between successive assertions of this control signal. Tx_Disable can also be asserted via the twowire serial interface address A2h, byte 110, bit 6 and monitored address A2h, byte 110, bit The contents of A2h, byte 110, bit 6 are logic OR’d with hardware Tx_Disable pin 3 to control transmitter operation.. Transmit Fault Tx_Fault A catastrophic laser fault will activate the transmitter signal, TX_FAULT, and disable the laser. This signal is an open collector output pull-up required on the host board . A low signal indicates normal laser operation and a high signal indicates a fault. 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 Eye Safety Circuit The AFBR-57J7APZ provides Class 1 single fault tolerant eye safety by design and has been tested for compliance with the requirements listed in Table 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 certification. Such unsafe conditions can be due to inputs from the host board Vcc fluctuation, unbalanced code or a fault within the transceiver. Receiver Section The receiver section includes the Receiver Optical SubAssembly ROSA and the amplification/quantization circuitry. The ROSA, containing a PIN photodiode and custom transimpedance amplifier, is located at the optical interface and mates with the LC optical connector. The ROSA output is fed to a custom IC that provides postamplification and quantization.

Performance degradation or device failure may result. Connection of the AFBR-57J7APZ to a light source not compliant with these specifications, operating above maximum operating conditions or in a manner inconsistent with it’s design and function may result in exposure to hazardous light radiation and may constitute an act of modifying or man- ufacturing a laser product. Persons performing such an act are required by law to re-certify and re-identify the laser product under the provisions of U.S. 21 CFR Subchapter J and TUV.

The transceiver performance is offered as a figure of merit to assist the designer Electrostatic Discharge ESD The AFBR-57J7APZ is compatible with ESD levels found in typical manufacturing and operating environments as described in Table In the normal handling and operation of optical transceivers, ESD is of concern in two circumstances. The first case is during handling of the transceiver prior to insertion into an SFP compliant cage. To protect the device, it’s important to use normal ESD handling precautions. These include using of grounded wrist straps, workbenches and floor wherever a transceiver is handled. The second case to consider is static discharges to the exterior of the host equipment chassis after installation. If the optical interface is exposed to the exterior of host equipment cabinet, the transceiver may be subject to system level ESD requirements. 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-57J7APZ’s compliance to these standards is detailed in Table The metal housing and shielded design of the AFBR-57J7APZ minimizes the EMI challenge facing the equipment designer. EMI Immunity Susceptibility Due to its shielded design, the EMI immunity of the AFBR57J7APZ exceeds typical industry standards. Flammability The AFBR-57J7APZ optical transceiver is made of metal and high strength, heat resistant, chemical resistant and UL 94V-0 flame retardant plastic. plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free transmission. Predictive Failure Identification The AFBR-57J7APZ predictive failure feature allows a host to identify potential link problems before system performance is impacted. Prior identification of link problems enables a host to service an application via “fail over” to a redundant link or replace a suspect device, maintaining system uptime in the process. For applications where ultra-high system uptime is required, a digital SFP provides a means to monitor two real-time laser metrics associated with observing laser degradation and predicting failure average laser bias current Tx_Bias and average laser optical power Tx_Power . Compliance Prediction: Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-57J7APZ devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify potential component compliance issues. Received optical power is also available to assess compliance of a cable Table Regulatory Compliance Fault Isolation The fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing downtime.

Component Monitoring Component evaluation is a more casual use of the AFBR-57J7APZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power. Potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory or field qualification.
