Avago AFBR-57D7APZ 8Gbit Short Wave Fibre Channel SFP+ Optical Transceiver

The Avago AFBR-57D7APZ is a high-performance, short-wavelength (850 nm) optical transceiver module designed for Fibre Channel (FC) storage area networks (SAN). It supports multi-rate data links at 8.5, 4.25, and 2.125 GBd, ensuring backward compatibility with legacy 4GFC and 2GFC infrastructure. This Small Form-Factor Pluggable (SFP+) device utilizes a Vertical-Cavity Surface-Emitting Laser (VCSEL) technology to deliver high-speed data transmission over multimode fiber (MMF). The module is capable of supporting link distances up to 150 meters on OM3 fiber and up to 190 meters on OM4 fiber, making it an ideal solution for intra-datacenter connectivity between switches, directors, and host bus adapters (HBAs). The AFBR-57D7APZ is fully compliant with the SFP+ Multi-Source Agreement (MSA) and meets the physical layer requirements defined in the FC-PI-4 standards. It features an integrated Digital Diagnostic Monitoring (DDM) interface, which allows real-time remote access to critical operating parameters such as laser bias current, optical transmit/receive power, transceiver temperature, and supply voltage. This telemetry is vital for proactive network health monitoring and rapid fault isolation in enterprise-class storage environments. The transceiver is designed with a standard LC duplex connector and operates on a single 3.3V power supply with a low power consumption profile (typically < 0.6W).
Built for carrier-grade reliability, the unit is housed in a robust metallic enclosure to enhance electromagnetic interference (EMI) shielding and mechanical durability. It is hot-pluggable, allowing for non-disruptive installation or replacement while the host system is operational. The AFBR-57D7APZ also includes an internal clock and data recovery (CDR) circuit to maintain signal integrity and minimize jitter across high-speed serial links. The module is lead-free, RoHS compliant, and certified for operation within a standard commercial temperature range (0°C to 70°C), providing a sustainable and stable interface for modern high-density data center deployments.
