Product details

Overview

AFBR-57F5PZ from Broadcom (formerly Avago Technologies) is a multi-rate SFP+ optical transceiver for Fibre Channel applications, featuring an 850nm VCSEL transmitter and PIN photodiode receiver, supporting 14.025 Gb/s (16GFC), 8.5 Gb/s (8GFC), and 4.25 Gb/s (4GFC) data rates with integrated CDRs on both TX and RX paths, real-time digital diagnostics per SFF-8472, and LC duplex optical interface compliant with FOCIS 10A.

For engineers reviewing the AFBR-57F5PZ datasheet, pinout, applications, or equivalent options, this page delivers verified specifications including rate-select–controlled CDR engagement, SFF-8472 diagnostic monitoring (Tx_Bias, Tx_Power, Rx_Power, temperature, Vcc), eye-safety compliance (IEC60825-1/CDRH Class 1), and SFP+ mechanical/electrical conformance per SFF-8432 and FC-PI-5.

Technical Context

The AFBR-57F5PZ implements dual independent rate-select inputs (RS(0) for RX, RS(1) for TX) to enable or bypass internal CDRs-engaged only at 14.025 Gb/s and bypassed at 8.5/4.25 Gb/s-ensuring FC-PI-5 compliance across all three speeds. Its transmitter uses a Class 1 eye-safe 850nm VCSEL with integral power monitoring, while the receiver employs a high-speed PIN detector with variable output emphasis and real-time jitter characterization (TJ = 0.36 UI @ 14.025 Gb/s with CDR).

Digital diagnostics are delivered via a 2-wire serial interface (SCL/SDA at addresses 0xA0 and 0xA2) conforming to SFF-8472 and AT24C01A EEPROM protocol, providing predictive failure identification (via Tx_Bias and Tx_Power trends), compliance prediction (Vcc, temperature, Rx_Power), fault isolation (Tx_Fault, Rx_LOS status flags), and component monitoring-all accessible without host SERDES interruption.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Fibre Channel transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AFBR-57D7APZ	850nm SFP (not SFP+) supporting 8G/4G/2GFC only; no CDR; max data rate 8.5 Gb/s; SFF-8472 diagnostics included.	Limited to 8GFC infrastructure; lacks 16GFC capability and hot-plug SFP+ mechanical compliance.	Select when upgrading legacy 8GFC systems without 16GFC requirements and cost sensitivity outweighs future scalability.
AFCT-57D5ATPZ	1310nm SFP supporting 8G/4G/2GFC over single-mode fiber; higher reach (up to 10 km); no CDR; different wavelength and dispersion characteristics.	Used in campus- or metro-distance FC links; incompatible with multimode 16GFC switch ports due to wavelength and form factor mismatch.	Select only for long-haul FC connections where SMF infrastructure exists and 16GFC is not required.

Compared with AFBR-57D7APZ and AFCT-57D5ATPZ, the AFBR-57F5PZ uniquely supports 16GFC with CDR-enabled jitter tolerance, SFP+ hot-plug compliance, and full SFF-8472 diagnostic coverage-making it the only option for new-generation Fibre Channel switch and HBA designs targeting 14.025 Gb/s operation on multimode fiber.

FAQ

What data rates does the AFBR-57F5PZ support, and how is rate selection controlled?

The AFBR-57F5PZ supports 14.025 Gb/s (16GFC), 8.5 Gb/s (8GFC), and 4.25 Gb/s (4GFC). Rate selection is controlled independently for transmit and receive paths using two dedicated pins: RS(1) (pin 9) for TX and RS(0) (pin 7). A logic high engages the internal CDR for 14.025 Gb/s operation; a logic low bypasses the CDR for lower rates. This allows asymmetric speed negotiation during Fibre Channel link initialization.

Is the AFBR-57F5PZ compliant with Fibre Channel standards, and which specific FC-PI-5 profiles does it meet?

Yes, the AFBR-57F5PZ is fully compliant with ANSI Fibre Channel FC-PI-5, supporting multiple optical link profiles: 1600-SN-M6-S, 800-SN-M6-S, 400-SN-M6-I, and equivalents for M5 and M5E/F variants. It meets FC-PI-5 requirements for 16GFC, 8GFC, and 4GFC-including optical waveform distortion penalty (TWDP ≤ 4.3 dB at 8.5 Gb/s), vertical eye closure penalty (VECP ≤ 2.56 dB at 14.025 Gb/s), and jitter specifications with and without CDR engagement.

How does the AFBR-57F5PZ implement Class 1 eye safety, and what happens during a safety event?

The AFBR-57F5PZ achieves Class 1 eye safety per IEC60825-1 and FDA CDRH through hardware-enforced optical power limiting and continuous real-time monitoring of VCSEL output. If unsafe optical power is detected-due to Vcc fluctuation, signal imbalance, or internal fault-the eye safety circuit automatically disables the transmitter. The TX_FAULT pin (pin 2) latches high to indicate the fault, and recovery requires toggling TX_DISABLE or power cycling the AFBR-57F5PZ.

What diagnostic parameters are available via the SFF-8472 interface on the AFBR-57F5PZ?

The AFBR-57F5PZ provides full SFF-8472 diagnostic monitoring via its 2-wire serial interface (addresses 0xA0 and 0xA2), including real-time values for transmitter average optical power (Tx_Power), received average optical power (Rx_Power), laser bias current (Tx_Bias), module temperature, and supply voltage (Vcc). Status flags such as TX_FAULT, RX_LOS, and TX_DISABLE state are also mirrored in memory for host polling and alarm generation.

Does the AFBR-57F5PZ support hot-plug insertion, and what mechanical standard does it follow?

Yes, the AFBR-57F5PZ is fully hot-pluggable and complies with the SFF-8074i and SFF-8432 mechanical specifications for SFP+ modules. It can be inserted or removed from any SFF-8074i–compliant SFP cage while the host system remains powered and operational. Initial contact between the transceiver housing and the host cage mitigates electrostatic discharge (ESD) risk during insertion.
