Data Sheet AFBR-57B4APZ DC-50 MBaud 850 nm Multimode LC Duplex SFP Transceiver Module Package Description The transceiver package is compatible with the Small Form The SFP transceiver provides system designers the ability Pluggable (SFP) MSA with the LC duplex connector option. to implement DC-50 MBaud data transmission over 2 km The hot-pluggable capability of the SFP package allows the with (62.5 m/125 m) multimode fibers. The transceiver module to be installed even when host is on-line and supports LC duplex connector and is lead free, RoHS operating. The transceiver requires a 3.3V DC power supply compliant. Using the 2-wire serial interface defined in the for optimal performance. SFF-8472 MSA, the AFBR-57B4APZ provides real-time information on module temperature, transmitter supply voltage and receiver average input power. Features Data rate support from DC to 50 MBaud Transmitter Single 3.3V power supply The transmitter consists of 850 nm class 1 laser compliant Manufactured in an ISO 9001 certified facility VCSEL with an integrated driver IC. The VCSEL driver 850 nm VCSEL transmitter operates at 3.3V. It receives LVTTL electrical input and Link Distance up to 2 km with 62.5 m/125 m converts it into a modulated current driving the VCSEL. The multimode fiber VCSEL is packaged in an optical subassembly. Low current and low power dissipation Hot pluggable SFP connector The optimized lens system of the optical subassembly Compatible with SFP MSA specification couples the emitted optical power very efficiently into multimode fibers. Class 1 FDA IEC60825-1 laser safety compliant Operating temperature 40C to +85C Excellent EMI and EMC behavior Receiver Integrated 850 nm VCSEL and driver IC with LVTTL The receiver utilizes a fully integrated single-chip solution input logic transmitter which provides excellent immunity to EMI and fast transient Integrated PIN diode and digitalizing IC with LVTTL dV/dt rejection. The receiver directly converts optical signal output logic receiver to a digital LVTTL/LVCMOS signal. Receiver operates 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 Table 1 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-57B4APZ-DS100 2
