Product details

Overview

AFBR-57E6APZ from Broadcom (formerly Avago Technologies) is a multimode SFP transceiver with LC duplex connector, supporting FDDI and 100Base-FX Fast Ethernet over 50/125μm and 62.5/125μm fiber. It integrates a 1310nm InGaAsP LED transmitter and InGaAs PIN photodiode receiver, delivers differential LVPECL outputs and PECL inputs, and operates from a single +3.3V supply across –40°C to +85°C.

For engineers reviewing the AFBR-57E6APZ datasheet, pinout, applications, or equivalent options, key selection considerations include its SFF-8472 digital diagnostic interface (real-time temperature, Tx bias, Tx/Rx optical power, RX_LOS), hot-pluggable SFP mechanical compliance, AC-coupled 100Ω differential I/O, and guaranteed –31 dBm receiver sensitivity for industrial Fast Ethernet links.

Technical Context

The AFBR-57E6APZ implements a fully integrated optical transceiver architecture: the transmitter uses an internally monitored InGaAsP LED driven by a PECL-to-analog IC, while the receiver employs an InGaAs PIN photodiode with transimpedance pre- and post-amplification, delivering squelched LVPECL data outputs and a +3.3V TTL LOS signal. All analog monitoring data is accessible via SFF-8472-compliant 2-wire serial interface (I²C) at address 0xA2.

It conforms to SFF-8074i and enhanced SFF-8472 MSA specifications, supports 125 MBd 4B/5B encoded signaling, and features three-stage hot-plug pin sequencing (ground → power → signal) with ESD-protected LC receptacle and metal housing for robust EMI immunity in factory automation environments.

Key Specifications

Pinout & Package

The AFBR-57E6APZ uses the industry-standard Small Form Factor Pluggable (SFP) package with LC duplex optical interface, 20-pin edge-card electrical interface, and bail-latch hot-plug mechanism. Dimensions are 13.4 × 8.5 × 55.2 mm (L×W×H), compliant with SFF-8472 mechanical specifications.

Pin/Terminal	Circuit Role	Design Meaning
1, 17, 20, VEET	Transmitter Ground	Common reference for Tx driver circuitry; internally connected to all VEET pins for low-impedance return path.
3, TxDisable	Transmitter Disable Control	Active-high logic input; disables LED output when high or open, enabling host-controlled optical shutdown.
4, 5, MOD-DEF2/1	I²C Serial Interface	SDA (pin 4) and SCL (pin 5) for SFF-8472 diagnostics; require 4.7k–10kΩ pull-up on host board.
8, LOS	Loss of Signal Output	Open-drain TTL output; asserted high when received optical power falls below –32 dBm threshold.
9–11, 14, VEER	Receiver Ground	Common reference for Rx amplifier chain; isolated from VEET but connected internally on module PCB.
12–13, RD−/RD+	Differential Receiver Output	LVPECL-compatible AC-coupled outputs; internally terminated to 100Ω, requiring external 100Ω diff termination at SERDES.
18–19, TD−/TD+	Differential Transmitter Input	PECL-compatible AC-coupled inputs; internally terminated and coupled-no external caps needed on host board.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AFBR-57E5APZ	Lacks SFF-8472 digital diagnostics; no real-time temperature, Tx bias, or optical power monitoring.	Suitable only for cost-sensitive, non-monitored links where diagnostics are not required for maintenance or compliance.	Select AFBR-57E5APZ only if diagnostic capability is unnecessary and BOM cost reduction is prioritized over operational visibility.
HFBR-5710LP	Uses different optical subassembly; specified for 100Base-SX (850 nm VCSEL), not 1310 nm LED; incompatible fiber type and distance budget.	Designed for shorter-reach 500 m over 50/125μm OM2 fiber-not interoperable with AFBR-57E6APZ's 2 km FDDI/Fast Ethernet reach.	HFBR-5710LP is not a functional substitute-only consider if migrating to 850 nm short-wavelength infrastructure with new fiber plant.

Compared with AFBR-57E5APZ and HFBR-5710LP, the AFBR-57E6APZ uniquely delivers SFF-8472 diagnostics with 1310 nm LED performance over legacy multimode fiber, making it the sole option for monitored, long-reach industrial Fast Ethernet deployments requiring backward compatibility with FDDI infrastructure.

FAQ

What is the optical wavelength and fiber compatibility of the AFBR-57E6APZ?

The AFBR-57E6APZ operates at a 1310 nm central wavelength and is optimized for use with both 62.5/125 μm (NA = 0.275) and 50/125 μm (NA = 0.20) multimode fiber. Its transmitter delivers –20.0 to –14.0 dBm output power into 62.5/125 μm fiber, supporting up to 2 km reach in 100Base-FX Fast Ethernet applications per IEEE 802.3u. The AFBR-57E6APZ does not support single-mode fiber or 850 nm VCSEL-based standards like 100Base-SX.

Does the AFBR-57E6APZ support digital diagnostics, and how is the interface implemented?

Yes, the AFBR-57E6APZ fully supports SFF-8472 digital diagnostics via a 2-wire I²C interface at address 0xA2. It provides real-time readout of case temperature (±3°C accuracy), transmitter LED bias current (±10%), transmitted optical power (±3 dB), received optical power (±3 dB), and RX_LOS status. The interface uses MOD-DEF1 (SCL) and MOD-DEF2 (SDA) pins and requires 4.7k–10kΩ pull-ups on the host board. Diagnostic data is accessible without modifying the AFBR-57E6APZ hardware.

What are the power supply requirements and thermal operating limits for the AFBR-57E6APZ?

The AFBR-57E6APZ requires a single +3.3 V supply with ±10% tolerance (3.0–3.6 V). Total supply current is 45–70 mA for the transmitter and 31–40 mA for the receiver, resulting in typical power dissipation of 255 mW. It is rated for case operating temperatures from –40°C to +85°C, with temperature measured at the top surface per Figure 5 in the datasheet. Operation outside this range may cause permanent damage or parametric failure.

How does the AFBR-57E6APZ implement Loss of Signal (LOS) detection and squelching?

The AFBR-57E6APZ asserts its open-drain LOS output high when received optical power drops below –32.0 dBm (de-assertion threshold) and de-asserts it when power rises above –31.0 dBm (hysteresis of 1.0 dB). The receiver outputs (RD+/RD−) are automatically squelched-driven to a defined idle state-when LOS is asserted. This behavior prevents invalid data propagation during link loss and is fully compliant with SFF-8074i and IEEE 802.3u requirements for Fast Ethernet receivers.

Is the AFBR-57E6APZ RoHS compliant and certified for eye safety?

Yes, the AFBR-57E6APZ is RoHS compliant per Directive 2011/65/EU Annex II and lead-free. It is classified as Class 1 laser product per EN 60825-1:2007 and EN 60825-2:2004+A1+A2, verified under both normal operation and single-fault conditions. The metal housing and UL-94V-0 flame-retardant plastic enclosure meet industrial safety and flammability requirements, and ESD immunity exceeds 9 kV contact discharge on the LC receptacle per IEC 61000-4-2.
