Product details
Overview
AFBR-57E6APZC from Broadcom is a multimode SFP optical transceiver with LC duplex interface, designed for 100Base-FX Fast Ethernet over 50/125-μm and 62.5/125-μm fiber. It integrates a 1310-nm InGaAsP LED transmitter and InGaAs PIN photodiode receiver, supports digital diagnostics per SFF-8472, operates from –40°C to +85°C, and features conformal-coated PCB for harsh environments.
For engineers reviewing the AFBR-57E6APZC datasheet, pinout, applications, or equivalent options, key selection considerations include its SFF-8472-compliant 2-wire diagnostic interface (temperature, Tx bias, Rx input power, LOS), LVPECL differential I/O, single 3.3V supply, and industrial-grade ESD/EMI robustness validated per EIA-364-65B Class IIIA and ASTM B117.
Technical Context
The AFBR-57E6APZC implements a full-duplex 125 MBd Fast Ethernet optical link using AC-coupled LVPECL data paths (TD±/RD±) with internal 100Ω termination and integrated squelch logic. Its digital diagnostic monitor uses an AT24C02C-compatible 2-wire interface at address 0xA2 to report real-time temperature, LED bias current, transmitted optical power, and received optical power with ±3.0 dB accuracy.
Transmitter disable (TX_DISABLE) is supported via both hardware (pin 3) and software (SFF-8472 byte 110, bit 6), with hardware assert time ≤10 μs and deassert time ≤30 μs. Receiver LOS output (pin 8) is TTL-compatible (+3.3V), asserted when input optical power falls below –32.0 dBm and deasserted above –45 dBm, with 0.5–1.6 dB hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar optical transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-57E5APZ | No SFF-8472 diagnostics; lacks real-time temperature, Tx bias, and Rx power monitoring | Suitable only where basic link status (LOS) suffices; no predictive maintenance capability | Select AFBR-57E5APZ only if diagnostic functionality is unnecessary and cost is primary constraint |
| AFBR-57E6APZ | Same optical specs and SFF-8472 compliance, but lacks conformal coating on PCB | Not rated for harsh environments per EIA-364-65B Class IIIA or ASTM B117 | Choose AFBR-57E6APZ only for controlled indoor deployments where environmental protection is not required |

FAQ
What is the optical wavelength and fiber compatibility of the AFBR-57E6APZC?
The AFBR-57E6APZC operates at a center wavelength of 1310 nm with spectral width ≤147 nm FWHM and is fully compatible with both 62.5/125-μm (NA=0.275) and 50/125-μm (NA=0.20) multimode fiber. Its output power range (–20.0 to –14.0 dBm on 62.5/125 μm) ensures ≥1 km reach in standard OM1 installations while maintaining IEEE 802.3u 100Base-FX compliance.
Does the AFBR-57E6APZC support digital diagnostics, and what parameters are monitored?
Yes, the AFBR-57E6APZC fully supports SFF-8472 digital diagnostics via its 2-wire serial interface (address 0xA2). It monitors real-time internal temperature (±3.0°C accuracy), LED bias current (±10% accuracy), transmitted average optical power (±3.0 dB), received average optical input power (±3.0 dB), and Loss of Signal status - all accessible through standardized memory map registers.
What is the operating temperature range and environmental qualification of the AFBR-57E6APZC?
The AFBR-57E6APZC is rated for case operating temperatures from –40°C to +85°C and is qualified for harsh environments per EIA-364-65B Class IIIA and ASTM B117 salt-spray testing. Its PCB features conformal coating (except at contact pads), and the metal housing provides EMI shielding - making it suitable for factory automation, outdoor enclosures, and industrial control cabinets.
How does the AFBR-57E6APZC implement transmitter disable and loss-of-signal detection?
The AFBR-57E6APZC supports hardware TX_DISABLE on pin 3 (active-high or open) with ≤10 μs assert time, and software-controlled disable via SFF-8472 byte 110, bit 6. Its LOS output (pin 8) is a +3.3V TTL open-drain signal that asserts when received optical power drops below –32.0 dBm and deasserts above –45 dBm, with 0.5–1.6 dB hysteresis to prevent chatter.
What are the power supply requirements and electrical interface standards for the AFBR-57E6APZC?
The AFBR-57E6APZC requires a single 3.3V supply (3.0–3.6 V) with typical transmitter current draw of 45 mA and receiver current of 31 mA.
