AFBR-709SMZ 10Gb Ethernet, 850 nm, 10GBASE-SR/SW, SFP+ Transceiver Data Sheet MZ 9S -70 BR AF Description Features The Avago AFBR-709SMZ 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 and 10GBASE-SW standards. The AFBR-709SMZ transceiver is designed to enable 10Gb Ethernet equipment designs with very high port density based on the new electrical and mechanical 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 development activities. • Avago 850nm VCSEL source and Transmitter Optical Subassembly technology Related Products • Link lengths at 10.3125 GBd: 300m with 50um OM3 MM fiber 400m with 50um OM4 MM fiber • The AFBR-709ASMZ is an SFP+ 10 Gigabit Ethernet 10GBASE-SR/SW transceiver with case temperature operated at 0-85 °C for use on multimode fiber cables.

It can be installed in any INF-8074 or SFF-8431/2 compliant Small Form Pluggable (SFP) port regardless of host equipment operating status The AFBR-709SMZ 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). Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-709SMZ 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 plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free transmission. Digital Diagnostic Interface and Serial Identification Fault Isolation The two-wire interface protocol and signaling detail are based on SFF-8431. Conventional EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with SFF-8431. 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. The fault isolation feature allows a host to quickly pinpoint 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 speeding service of an installation. AFBR-709SMZ 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_DISABLE and Rx Loss of Signal (LOS) are mirrored in memory and available via the two-wire serial interface. Predictive Failure Identification The AFBR-709SMZ 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). 2 Component Monitoring Component evaluation is a more casual use of the AFBR-709SMZ 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. For example, temperature per module can be observed in high density applications to facilitate thermal evaluation of blades, PCI cards and systems.

Transceiver functional diagram Transmitter Section Transmit Fault (TX_FAULT) The transmitter section includes the Transmitter Optical Sub-Assembly (TOSA) and laser driver circuitry. The TOSA, containing an Avago designed and manufactured 850 nm 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 an 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. 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 2). Transmit Disable (TX_DISABLE) The AFBR-709SMZ accepts an LVTTL compatible transmit disable control signal input 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 6. An internal pull up resistor disables the transceiver transmitter until the host pulls the input low. TX_DISABLE can also be asserted via the two-wire interface (address A2h, byte 110, bit 6) and monitored (address A2h, byte 110, bit 7). The contents of A2h, byte 110, bit 6 are logic OR’d with hardware TX_DISABLE (contact 3) to control transmitter operation. 3 Receiver Section Caution 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. The post-amp IC also includes transition detection circuitry which monitors the AC level of incoming optical signals and provides a LVTTL/CMOS compatible status signal to the host. A high status signal indicates loss of modulated signal, indicating link failures such as broken fiber or failed transmitter. Rx_LOS can also be monitored via the two-wire serial interface(address A2h, byte 110, bit 1). There are no user serviceable parts nor maintenance requirements for the AFBR-709SMZ. All mechanical adjustments are made at the factory prior to shipment. Tampering with, modifying, misusing or improperly handling the AFBR-709SMZ will void the product warranty. It may also result in improper operation and possibly overstress the laser source. Performance degrada­tion or device failure may result. Connection of the AFBR-709SMZ to a light source not compliant with IEEE Std. 802.3ae Clause 52 and SFF-8341 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 manufacturing a laser product. Persons performing such an act are required by law to recertify and re-identify the laser product under the provisions of U.S. 21 CFR (Subchapter J) and TUV. Functional Data I/O Customer Manufacturing Processes The AFBR-709SMZ 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. This module is pluggable and is not designed for aqueous wash, IR reflow, or wave soldering processes. Receiver Loss of Signal (Rx_LOS) The AFBR-709SMZ high speed transmit and receive in­ terfaces require SFF-8431 compliant signal lines on the host board. To simplify board requirements, biasing resistors 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. If an application does not take advantage of these func­tions, care must be taken to ground TX_DISABLE to enable normal operation. Figure 2 depicts the recom­mended interface circuit to link the AFBR-709SMZ to supporting physical layer ICs. Timing for the dedicated SFP+ control signals implemented in the transceiver are listed in Figure 6.

Regulatory Compliance Electromagnetic Interference (EMI) The AFBR-709SMZ complies with all applicable laws and regulations as detailed in Table 1. Certification level is dependent on the overall configuration of the host equipment. The transceiver performance is offered as a figure of merit to assist the designer. Equipment incorporating 10 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-709SMZ enables equipment compliance to these standards detailed in Table 1. The metal housing and shielded design of the AFBR-709SMZ minimizes the EMI challenge facing the equipment designer. For superior EMI performance it is recommended that equipment designs utilize SFP+ cages per SFF 8432. Electrostatic Discharge (ESD) The AFBR-709SMZ is compatible with ESD levels found in typical manufacturing and operating environments as described in Table 1. 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 use of grounded wrist straps, work-benches 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. RF Immunity (Susceptibility) Due to its shielded design, the EMI immunity of the AFBR-709SMZ exceeds typical industry standards. Eye Safety The AFBR-709SMZ 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 a condition beyond the scope of Class 1 certification Such conditions can be due to inputs from the host board (Vcc fluctuation, unbalanced code) or a fault within the transceiver. US CDRH and EU TUV certificates are listed in table 1. Flammability The AFBR-709SMZ optical transceiver is made of metal and high strength, heat resistant, chemical resistant and UL 94V-0 flame retardant plastic. 5 Table 1.
