Data Sheet AFBR-57B4APZC DC-50 MBaud 850-nm Multimode LC Duplex SFP Transceiver with Conformal Coating Description Module Package The SFP transceiver provides system designers the ability The transceiver package is compatible with the Small Form to implement DC-50 MBaud data transmission over 2 km Pluggable (SFP) MSA with the LC duplex connector option. with (62.5 m/125 m) multimode fibers. The transceiver The hot-pluggable capability of the SFP package allows the supports LC duplex connector and is lead free, RoHS module to be installed even when host is online and compliant. Using the 2-wire serial interface defined in the operating. The transceiver requires a 3.3V DC power supply SFF-8472 MSA, the AFBR-57B4APZC provides real-time for optimal performance. information on module temperature, transmitter supply Features voltage and receiver average input power. The transceiver exhibits increased robustness in harsh environments due to Data rate support from DC to 50 MBaud conformal coating. Single 3.3V power supply Manufactured in an ISO 9001 certified facility Transmitter 850 nm VCSEL transmitter Link distance up to 2 km with 62.5 m/125 m The transmitter consists of 850 nm Class 1 laser compliant multimode fiber VCSEL with an integrated driver IC. The VCSEL driver Low current and low power dissipation operates at 3.3V. It receives LVTTL electrical input and Hot pluggable SFP connector converts it into a modulated current driving the VCSEL. The Compatible with SFP MSA specification VCSEL is packaged in an optical subassembly. Class 1 FDA IEC60825-1 laser safety compliant The optimized lens system of the optical subassembly Operating temperature 40C to +85C couples the emitted optical power very efficiently into Excellent EMI and EMC behavior multimode fibers. Integrated 850 nm VCSEL and driver IC with LVTTL input logic transmitter Receiver Integrated PIN diode and digitalizing IC with LVTTL output logic receiver The receiver uses a fully integrated single-chip solution that Harsh environment tested according to IEC 60068-2-11 provides excellent immunity to EMI and fast transient dV/dt and GR-63-CORE rejection. The receiver directly converts optical signal to a digital LVTTL/LVCMOS signal. The receiver operates Applications at 3.3V.

The transceiver provides a DC-coupled data interface that is loaded with a current source of 15 A toward an internal reference voltage (1.2V). Regulatory Compliance See PCB Pin Connections for transceiver Regulatory Compliance performance. The overall equipment design will determine the certification level. The transceiver performance is offered as a figure of merit to assist the designer. Electrostatic Discharge (ESD) There are two conditions where immunity to ESD damage is important. Regulatory Compliance documents the transceiver s immunity to both of these conditions. The first condition is static discharge to the transceiver when handling for example, when the transceiver is inserted into the transceiver port. To protect the transceiver, it is important to use normal ESD handling procedures. The ESD sensitivity of the transceiver 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 at which the duplex LC optical interface is exposed to outer part of the host equipment chassis, transceiver may be subjected to system- level ESD events. The ESD performance of the transceiver exceeds typical industry standards. Broadcom AFBR-57B4APZC-DS101 2
