These transceivers are intended for premise, public and access networking applications. They are qualified in accordance with GR-468-CORE, and transmit data over single-mode (SM) fiber for a link distance of 10 km, in excess of the standard. The product package is compliant with the SFP MSA with the LC connector option. The SFP MSA includes specifications for mechanical packaging and performance as well as dc, ac and control signal timing and performance. The AFCT-5715Z family of optical transceivers adds digital diagnostic monitoring to standard SFP functionality, enabling fault isolation, components monitoring and failure prediction capabilities. General Features The AFCT-571xZ is compliant to 1 GbE specifications. This includes specifications for the signal coding, optical fiber and connector types, optical and electrical transmitter characteristics, optical and electrical receiver characteristics, jitter characteristics, and compliance testing methodology for the aforementioned. This transceiver is capable of implementing both Single Mode (SM) and Multimode (MM) optical fiber applications in that order of precedence in the event of conflicting specifications. In addition, the SM link type exceeds the 2 m to 5 km 1000BASE-LX specification by achieving compliance over 2 m to 10 km. The MM link type is expected to meet the 62.5 m MMF specification when used with an "offset launch" fiber. Optical Interface The power supply is 3.3 V dc. The High Speed I/O (HSIO) signal interface is a Low Voltage Differential type. It is ac coupled and terminated internally to the module. The internal termination is a 100 Ohm differential load. Installation The AFCT-571xZ can be installed in or removed from any MSA-compliant Pluggable Small Form Factor (SFP) port regardless of whether the host equipment is operating or not. The module is simply inserted, electrical-interface first, under finger-pressure. Controlled hotplugging is ensured by 3-stage pin sequencing at the electrical interface. This printed circuit board card-edge connector is depicted in Figure 2. As the module is inserted, first contact is made by the housing ground shield, discharging any potentially component-damaging static electricity. Ground pins engage next and are followed by Tx and Rx power supplies. Finally, signal lines are connected. Pin functions and sequencing are listed in Table 2.

The driver circuit maintains a constant optical power level provided that the data pattern is valid 8B/10B code. Connection to the transmitter is provided via a LC optical connector. The transmitter has full IEC 60825 and CDRH Class 1 eye safety. TX_DISABLE The transmitter output can be disabled by asserting pin 3, TX_DISABLE. A high signal asserts this function while a low signal allows normal laser operation. In addition, via the 2-wire serial interface the transmitter output can be disabled (address A2h, byte 110, bit 6) or monitored (address A2h, byte 110, bit 7). The contents of A2h, byte 110, bit 6 are logic OR'd with hardware Tx_Disable (pin 3) to control transmitter operation. In the event of a transceiver fault, such as the activation of the eye safety circuit, toggling of the TX_DISABLE will reset the transmitter, as depicted in Figure 4.

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 TX_FAULT is not latched for Low VCC. The transmitter fault condition can also be monitored via the two-wire serial interface (address A2h, byte 110, bit 2). Avago's AFCT-571xZ transceiver is designed to accept industry standard differential signals. The transceiver provides an AC-coupled, internally terminated data interface. Bias resistors and coupling capacitors have been included within the module to reduce the number of components required on the customer's board. Figure 2 illustrates the recommended interface circuit. Eye Safety Circuit Under normal operating conditions, the laser power will be maintained below the eye-safety limit. If the eye safety limit is exceeded at any time, a laser fault will occur and the TX_FAULT output will be activated. Receiver Section The receiver section for the AFCT-571xZ contains an InGaAs/InP photo detector and a preamplifier mounted in an optical subassembly. This optical subassembly is coupled to a post amplifier/decision circuit on a circuit board. The design of the optical subassembly provides better than 12 dB Optical Return Loss (ORL). Connection to the receiver is provided via a LC optical connector. RX_LOS The receiver section contains a loss of signal (RX_LOS) circuit to indicate when the optical input signal power is insufficient for Gigabit Ethernet compliance. A high signal indicates loss of modulated signal, indicating link failure such as a broken fiber or a failed transmitter. RX_ LOS can be also be monitored via the two-wire serial (address A2h, byte 110, bit 1). VCCT 0.1 F 1 H VCCR 3.3 V 10 F The AFCT-571xZ family complies with the SFF-8074i specification, which defines the module's serial identification protocol to use the 2-wire serial CMOS EEPROM protocol of the ATMEL AT24C01A or similar. Standard SFP EEPROM bytes 0-255 are addressed per SFF-8074i at memory address 0xA0 (A0h). As an enhancement to the conventional SFP interface defined in SFF-8074i, the AFCT-5715Z is also compliant to SFF-8472 (the digital diagnostic interface for SFP). This enhancement adds digital diagnostic monitoring to standard SFP functionality, enabling failure prediction, fault isolation, and component monitoring capabilities. Using the 2-wire serial interface, the AFCT-5715Z provides real time access to transceiver internal supply voltage and temperature, transmitter output power, laser bias current and receiver average input power, allowing a host to predict system compliance issues. These five parameters are internally calibrated, per the MSA. New digital diagnostic information is accessed per SFF-8472 using EEPROM bytes 0-255 at memory address 0xA2 (A2h). The digital diagnostic interface also adds the ability to disable the transmitter (TX_DISABLE), monitor for Transmitter Faults (TX_FAULT) and monitor for Receiver Loss of Signal (RX_LOS). Contents of the MSA-compliant serial ID memory are shown in Tables 10 through 14. The SFF-8074i and SFF-8472 specifications are available from the SFF Committee at http://www.sffcommittee.org. 1 H 0.1 F Digital Diagnostic Interface and Serial Identification 0.1 F 10 F The I2C accessible memory page address 0xB0 is used internally by SFP for the test and diagnostic purposes and it is reserved. Predictive Failure Identification SFP MODULE HOST BOARD Figure 4. MSA required power supply filter 4 The diagnostic information allows the host system to identify potential link problems. Once identified, a fail-over technique can be used to isolate and replace suspect devices before system uptime is impacted. Compliance Prediction Operating Temperature The real-time diagnostic parameters can be monitored to alert the system when operating limits are exceeded and compliance cannot be ensured. The AFCT-571xZ family is available in either Extended (-10 to +85C) or Industrial (-40 to +85C) temperature ranges. Fault Isolation Power Supply Noise The diagnostic information can allow the host to pinpoint the location of a link problem and accelerate system servicing and minimize downtime. The AFCT-571xZ can withstand an injection of PSN on the VCC lines of 100 mV ac with a degradation in eye mask margin of up to 10% on the transmitter and a 1 dB sensitivity penalty on the receiver. This occurs when the product is used in conjunction with the MSA recommended power supply filter shown in Figure 3. Component Monitoring As part of the host system monitoring, the real time diagnostic information can be combined with system level monitoring to ensure system reliability. Application Support An Evaluation Kit and Reference Designs are available to assist in evaluation of the AFCT-571xZ SFPs. Please contact your local Field Sales representative for availability and ordering details. Regulatory Compliance The transceiver regulatory compliance is provided in Table 1 as a figure of merit to assist the designer. The overall equipment design will determine the certification level.

Less than 1000ppm of: cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated biphenyl ethers Electrostatic Discharge (ESD) Eye Safety There are two conditions in which immunity to ESD damage is important: The AFCT-571xZ transceivers provide Class 1 eye safety by design. Avago Technologies has tested the transceiver design for regulatory compliance, under normal operating conditions and under a single fault condition. See Table 1. The first condition is static discharge to the transceiver during handling such as when the transceiver is inserted into the transceiver port. To protect the transceiver, it is important to use normal ESD handling precautions including the use of grounded wrist straps, work benches, and floor mats in ESD controlled areas. The ESD sensitivity of the AFCT-571xZ is compatible with typical industry production environments. The second condition is static discharge to the exterior of the host equipment chassis after installation. To the extent that the duplex LC optical interface is exposed to the outside of the host equipment chassis, it may be subject to system-level ESD requirements. The ESD performance of the AFCT-571xZ exceeds typical industry standards. Table 1 documents ESD immunity to both of these conditions. Electromagnetic Interference (EMI) Most equipment designs using the AFCT-571xZ SFPs are subject to the requirements of the FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. The metal housing and shielded design of the transceiver minimize EMI and provide excellent EMI performance. EMI Immunity The AFCT-571xZ transceivers have a shielded design to provide excellent immunity to radio frequency electromagnetic fields which may be present in some operating environments. 6 Flammability The AFCT-571xZ family of SFPs is compliant to UL 94V-0. Customer Manufacturing Processes This module is pluggable and is not designed for aqueous wash, IR reflow, or wave soldering processes. Caution The AFCT-571xZ contains no user-serviceable parts. Tampering with or modifying the performance of the AFCT-571xZ will result in voided product warranty. It may also result in improper operation of the transceiver circuitry, and possible over-stress of the laser source. Device degradation or product failure may result. Connection of the AFCT-571xZ to a non-approved optical source, operating above the recommended absolute maximum conditions may be considered an act of modifying or manufacturing a laser product. The person(s) performing such an act is required by law to re-certify and re-identify the laser product under the provisions of U.S. 21 CF. Table 2.
