Product details
Overview
AFBR-5701ALZ from Broadcom (formerly Avago) is an industrial-grade, hot-pluggable SFP optical transceiver supporting 1.25 GBd Gigabit Ethernet (1000BASE-SX) and 1.0625 GBd Fibre Channel (100-M5-SN-I/100-M6-SN-I) over multimode fiber. It features an 850 nm VCSEL transmitter, LC-duplex connector, -40°C to +85°C operating range, and no Digital Diagnostic Monitoring (DMI). It is deployed in enterprise storage switches and ruggedized network infrastructure requiring reliable short-reach optical links.
For engineers reviewing the AFBR-5701ALZ datasheet, pinout, applications, or equivalent options, key selection criteria include industrial temperature rating, absence of DMI functionality, SFF-8074i compliance, VCSEL-based 850 nm operation, and compatibility with MSA-compliant host interfaces for Gigabit Ethernet and Fibre Channel systems.
Technical Context
The AFBR-5701ALZ implements a fully integrated SFP transceiver architecture with separate TOSA (850 nm VCSEL) and ROSA (PIN photodiode + TIA) subassemblies. Its electrical interface conforms strictly to SFF-8074i, using differential TD+/TD− and RD+/RD− signals with internal AC coupling and 100 Ω termination.
It operates from a single +3.3 V supply (VccT/VccR = 3.135–3.465 V), incorporates eye safety circuitry compliant with FDA CDRH Class 1 and IEC 60825-1, and uses controlled 3-stage pin engagement sequencing for hot-plug reliability. No on-module EEPROM diagnostic functions are present - serial ID is limited to base A0h memory per SFF-8074i.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 17, 20, 9, 10, 11, 14 | VeeT / VeeR | Transmitter/receiver ground pins - provide low-inductance return paths; engage first during hot-plug |
| 15, 16 | VccR / VccT | +3.3 V receiver/transmitter supplies - engage second; must be within 0.5 V of each other |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SFP transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-5701LZ | Same core transceiver, but extended temperature range (-10°C to +85°C) and standard latch | Targeted at commercial data centers and enterprise wiring closets, not industrial enclosures | Select AFBR-5701LZ when ambient temperature stays above -10°C and cost optimization is prioritized over ruggedization |
| AFBR-5710Z | Functionally identical 1000BASE-SX SFP without DMI; same 850 nm VCSEL, but newer revision with updated reliability testing | Designed for high-volume OEM server NICs; shares footprint but differs in EEPROM content and qualification profile | Choose AFBR-5710Z for new designs requiring latest manufacturing lot traceability and extended Telcordia GR-468-CORE lifetime data |
Compared with AFBR-5701ALZ, AFBR-5701LZ trades industrial temperature tolerance for lower unit cost in climate-controlled settings, while AFBR-5710Z offers updated production validation for volume server deployments - neither provides DMI, preserving firmware simplicity where diagnostics are unnecessary.

FAQ
Does AFBR-5701ALZ support Digital Diagnostic Monitoring (DMI)?
No, AFBR-5701ALZ does not support DMI. It belongs to the AFBR-5701Z family, which implements only base SFF-8074i serial ID (A0h address) for module identification. Real-time monitoring of temperature, voltage, Tx bias, or optical power - defined in SFF-8472 - is exclusive to the AFBR-5705Z family. The AFBR-5701ALZ simplifies host firmware by omitting DMI register maps and polling requirements.
What is the maximum supported fiber distance for AFBR-5701ALZ in Gigabit Ethernet mode?
In 1000BASE-SX Gigabit Ethernet mode, AFBR-5701ALZ supports up to 550 meters over 50/125 µm multimode fiber (OM2/OM3) and up to 275 meters over 62.5/125 µm fiber (OM1), per IEEE 802.3 clause 38. These distances assume worst-case optical power budget (-9.5 dBm min output, -21 dBm sensitivity) and standard modal bandwidth fiber specifications.
Is AFBR-5701ALZ compatible with SFP ports that require DMI capability?
Yes, AFBR-5701ALZ is physically and electrically compatible with any MSA-compliant SFP port, including those designed for DMI-capable modules. Because it implements only the mandatory A0h serial ID memory map, hosts will recognize it as a valid SFP but will not attempt DMI reads from A2h - no software or hardware modification is needed. TX_FAULT, LOS, and TX_DISABLE pins remain fully functional.
What safety certifications apply to AFBR-5701ALZ?
AFBR-5701ALZ is certified Class 1 Laser Product per FDA 21 CFR 1040.10 (CDRH #9720151-57) and IEC 60825-1:2014, with additional compliance to UL 60950-1, CSA C22.2 No. 60950-1, and RoHS-6. Its eye safety circuit continuously monitors optical output and shuts down the VCSEL if unsafe conditions (e.g., open fiber, driver fault) are detected - no external interlocks required.
Can AFBR-5701ALZ be used in Fibre Channel applications?
Yes, AFBR-5701ALZ is explicitly qualified for Fibre Channel applications at 1.0625 GBd, compliant with FC-PI standards 100-M5-SN-I (50/125 µm) and 100-M6-SN-I (62.5/125 µm). It delivers -21 dBm receiver sensitivity and supports up to 500 m on OM2 fiber and 300 m on OM1, meeting FC-PI link budget requirements without requiring forward error correction or retiming.
