Product details
Overview
AFBR-5701APZ from Broadcom (formerly Avago) is an industrial-grade, hot-pluggable SFP optical transceiver for Gigabit Ethernet (1.25 GBd) and Fibre Channel (1.0625 GBd) applications. It features an 850 nm VCSEL transmitter, PIN photodiode receiver, LC-duplex connector, -40°C to +85°C operating range, and no Digital Diagnostic Monitoring Interface (DMI). It is used in enterprise storage switches and ruggedized network infrastructure requiring reliable multimode fiber links up to 550 m over 50/125 µm fiber.
For engineers reviewing the AFBR-5701APZ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical characteristics, SFP MSA-compliant pin functions, industrial temperature validation, eye-safety certification (FDA CDRH Class 1), and real-world deployment guidance for high-density, field-deployed optical interconnects.
Technical Context
The AFBR-5701APZ implements a fully integrated SFP transceiver architecture compliant with SFF-8074i and IEEE 802.3 1000BASE-SX. Its transmitter uses an 850 nm VCSEL driven by a custom laser driver with built-in eye safety circuitry that monitors optical output and asserts TX_FAULT on unsafe conditions. The receiver employs a PIN photodiode and transimpedance preamplifier with integrated LOS detection.
It supports differential LVPECL/CML inputs (TD±) and outputs (RD±), operates from a single +3.3 V supply (VccT/VccR), and uses three-stage hot-plug sequencing with housing ground-first engagement. Pin 6 (MOD-DEF0) is grounded internally to indicate module presence, while MOD-DEF1/2 provide I²C serial ID access at address A0h - but DMI functionality (A2h memory map) is excluded per its AFBR-5701Z family designation.

FAQ
What is the operating temperature range of the AFBR-5701APZ?
The AFBR-5701APZ is rated for industrial operation from -40°C to +85°C case temperature. This range is validated per Telcordia GR-468-CORE and confirmed in Table 4 of the official datasheet. It enables deployment in uncontrolled environments such as outdoor telecom cabinets, factory-floor switches, and transportation infrastructure where ambient extremes exceed commercial-grade limits. The AFBR-5701APZ achieves this via enhanced thermal design of the VCSEL driver and ROSA amplifier circuits.
Does the AFBR-5701APZ support Digital Diagnostic Monitoring (DMI)?
No, the AFBR-5701APZ does not support DMI. As a member of the AFBR-5701Z family, it omits the SFF-8472-compliant diagnostic EEPROM (address A2h) and associated real-time monitoring circuitry for parameters like temperature, Tx bias current, and received optical power. Only basic serial ID (A0h) is implemented. For DMI capability, select the AFBR-5705APZ variant - which shares identical packaging, temperature rating, and bail latch but adds full SFF-8472 compliance.
What fiber types and distances does the AFBR-5701APZ support?
The AFBR-5701APZ supports 50/125 µm OM2/OM3 multimode fiber up to 550 m at 1.25 GBd (1000BASE-SX) and up to 500 m at 1.0625 GBd (Fibre Channel 100-M5-SN-I). With 62.5/125 µm fiber, it reaches 275 m (Gigabit Ethernet) and 300 m (Fibre Channel). These distances assume compliant launch conditions and worst-case optical loss budgets per IEEE 802.3 and FC-PI standards - verified using the specified -9.5 dBm min. transmit power and -21 dBm receiver sensitivity.
How is the AFBR-5701APZ mechanically secured in the host SFP cage?
The AFBR-5701APZ uses a bail-style latching mechanism - distinct from the standard "leverage" latch found on AFBR-5701LZ/ALZ variants. The bail latch provides higher retention force and superior resistance to vibration-induced loosening, making it ideal for mobile or industrial applications. Mechanical drawings in the datasheet (Figure 7) confirm the bail's pivot point, travel arc, and engagement depth - all fully compliant with SFF-8074i dimensional tolerances.
Is the AFBR-5701APZ RoHS-6 compliant and certified for eye safety?
Yes, the AFBR-5701APZ is RoHS-6 compliant (≤1000 ppm cadmium, lead, mercury, hexavalent chromium, PBB, PBDE) and certified as FDA CDRH Class 1 and IEC 60825-1 Class 1 laser product (certification #9720151-57). Its eye safety is achieved through hardware-enforced optical power limiting and continuous monitoring by the integrated eye safety circuit - which disables the VCSEL and asserts TX_FAULT if output exceeds safe limits. No external safety interlocks are required.
