Product details
Overview
AFBR-57B4APZC from Broadcom is a DC–50 MBaud 850-nm multimode SFP transceiver with LC duplex connector, conformal coating, and Class 1 laser safety compliance. It delivers 2 km link distance over 62.5 µm/125 µm fiber, operates on single 3.3V supply, and supports real-time digital diagnostics via SFF-8472-compliant 2-wire interface for temperature, supply voltage, and received optical power monitoring - deployed in power substation automation and HVDC systems.
For engineers reviewing the AFBR-57B4APZC datasheet, pinout, applications, or equivalent options, key selection criteria include its –40°C to +85°C industrial operating range, UL-94V-0 flame-retardant metal-plastic housing, ESD robustness (9 kV contact to LC receptacle), and SFP MSA mechanical/electrical compatibility for hot-pluggable deployment in harsh environments.
Technical Context
The AFBR-57B4APZC integrates an 850 nm VCSEL transmitter with LVTTL input logic and driver IC, plus a fully integrated PIN diode receiver with LVTTL/LVCMOS output logic - both powered at 3.3 V. Its optical subassembly couples efficiently into 62.5 µm/125 µm multimode fiber, enabling DC–50 MBaud operation with PRBS27-1 pattern validation.
Digital diagnostics use dual EEPROM memory maps (0xA0 serial ID, 0xA2 diagnostic) compliant with SFF-8472, supporting real-time readout of internal temperature (±5°C accuracy), supply voltage (±0.1 V), and received optical power (±3.0 dB). The module features conformal coating and passes IEC 60068-2-11 and GR-63-CORE environmental testing.
Key Specifications

FAQ
What is the maximum supported link distance for AFBR-57B4APZC?
The AFBR-57B4APZC supports up to 2 km over 62.5 µm/125 µm multimode fiber with NA = 0.275. This distance is validated under full operating conditions (–40°C to +85°C) and with PRBS27-1 pattern at 50 MBaud. Performance beyond 2 km is not guaranteed and depends on fiber quality, splice loss, and connector reflectance.
Does AFBR-57B4APZC support digital diagnostics, and how is the interface implemented?
Yes, AFBR-57B4APZC implements SFF-8472-compliant digital diagnostics via a 2-wire serial interface (MOD-DEF1 = SCL, MOD-DEF2 = SDA) at address 0xA2. It provides real-time readout of internal temperature, supply voltage, transmitted optical power, and received optical power - all accessible through sequential reads to ensure coherent MSB/LSB retrieval.
What are the ESD protection ratings for AFBR-57B4APZC?
The AFBR-57B4APZC meets JEDEC JESD22-A114 Class 2 (2000–3999 V) for electrical pin ESD and withstands ≥9 kV contact discharge and ≥15 kV air discharge on the LC duplex receptacle per IEC 61000-4-2 variation. These ratings are verified per datasheet test methods and apply to both handling and system-level events.
Is AFBR-57B4APZC compatible with standard SFP host connectors and PCB layouts?
Yes, AFBR-57B4APZC complies fully with the SFP MSA mechanical and electrical specifications, including pinout, dimensions (Figure 4–6), and hot-plug timing. It mates with standard LC duplex receptacles and requires no modifications to host board layout or firmware - provided MOD-DEF pull-up resistors (4.7–10 kΩ) and proper 3.3 V filtering are implemented.
What environmental standards has AFBR-57B4APZC been tested against?
The AFBR-57B4APZC is qualified to IEC 60068-2-11 (salt mist), GR-63-CORE Section 5.5 (airborne contaminants), and operates across –40°C to +85°C.
