Product details
Overview
AFBR-57E6APZ-HT from Broadcom is a multimode SFP optical transceiver with LC duplex interface, 1310-nm InGaAsP LED transmitter and InGaAs PIN photodiode receiver, supporting 100BASE-FX Fast Ethernet at 125 MBd over 50/125 μm or 62.5/125 μm fiber, operating from –40°C to +95°C case temperature.
For engineers reviewing the AFBR-57E6APZ-HT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical/optical specs, SFF-8472 digital diagnostics implementation, hot-plug timing behavior, real-time monitoring of Tx bias current and Rx input power, and precise SFP MSA mechanical compliance for industrial embedded deployment.
Technical Context
The AFBR-57E6APZ-HT implements a differential PECL-to-LED driver and LVPECL-output receiver with integrated squelch logic triggered by Rx input power thresholds (–32 dBm de-assert, –45 dBm assert). Its digital diagnostic interface uses SFF-8472-compliant 2-wire serial bus (A0h/A2h addresses) with real-time monitoring of temperature (±3°C accuracy), supply voltage (±0.1 V), Tx bias current (±10%), and optical power (±3 dB).
It supports hardware TX_DISABLE (10 μs off, 30 μs on) and software-controlled disable via EEPROM register A2h byte 110 bit 6, with full SFF-8074i compatibility enhanced by SFF-8472 diagnostics - including alarm/warning thresholds, status flags, and soft LOS control - all operating under single +3.3 V supply with 3-stage hot-plug pin sequencing (ground → power → signal).

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 | Lacks SFF-8472 diagnostics; no real-time temperature, voltage, or optical power monitoring | Suitable only for basic plug-and-play deployments where diagnostics are not required | Select AFBR-57E5APZ only if cost sensitivity outweighs need for predictive health monitoring |
| AFBR-57E6APZ | Standard temperature grade (0°C to +70°C); same optical specs but no extended thermal validation | Restricted to commercial indoor environments; not qualified for industrial edge deployments | Choose AFBR-57E6APZ only when ambient conditions remain within 0–70°C and full diagnostics are needed |

FAQ
What is the operating temperature range of the AFBR-57E6APZ-HT?
The AFBR-57E6APZ-HT is rated for case operating temperatures from –40°C to +95°C, with all electrical and optical specifications guaranteed across this full range. This extended thermal performance is validated per Table 4 of the datasheet and enables deployment in uncontrolled industrial enclosures, outdoor cabinets, and rail-side equipment without external cooling or heating.
Does the AFBR-57E6APZ-HT support digital diagnostics per SFF-8472?
Yes, the AFBR-57E6APZ-HT fully implements SFF-8472 digital diagnostics via its 2-wire serial interface (MOD-DEF1/SCL and MOD-DEF2/SDA pins), providing real-time monitoring of internal temperature (±3°C accuracy), supply voltage (±0.1 V), LED bias current (±10%), and transmitted/received optical power (±3 dB) through address A2h memory map.
What fiber types and distances does the AFBR-57E6APZ-HT support?
The AFBR-57E6APZ-HT operates with both 62.5/125 μm (NA=0.275) and 50/125 μm (NA=0.20) multimode fiber, delivering –20.0 to –14.0 dBm output power into 62.5/125 μm fiber and –24.0 to –17.0 dBm into 50/125 μm fiber - enabling reliable 100BASE-FX links up to 2 km per IEEE 802.3u specification.
How does the AFBR-57E6APZ-HT handle hot-plug insertion?
The AFBR-57E6APZ-HT implements MSA-defined 3-stage hot-plug pin sequencing: ground pins (1, 9–11, 14, 17, 20) make contact first, followed by power pins (15, 16), then signal pins (3, 4, 5, 6, 8, 12, 13, 18, 19). This sequence prevents ESD damage, ensures controlled power-up, and avoids signal contention during live insertion.
What is the meaning of the "HT" suffix in AFBR-57E6APZ-HT?
The "HT" suffix in AFBR-57E6APZ-HT explicitly denotes High-Temperature qualification, confirming that the device is tested and guaranteed to meet all electrical, optical, and timing specifications across the full –40°C to +95°C case operating temperature range - distinguishing it from standard-grade variants like AFBR-57E6APZ (0°C to +70°C).
