Product details
Overview
AFBR-57L1APZ from Broadcom is a hot-pluggable SFP transceiver implementing 1.25-Gbaud Gigabit Ethernet over multimode fiber up to 2 km, featuring a 1310-nm FP laser transmitter, PIN photodiode receiver, real-time DMI monitoring of temperature, Tx bias current, Tx output power, and Rx input power, and operating across –40°C to +85°C for factory automation and substation networks.
For engineers reviewing the AFBR-57L1APZ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs (3.3V supply, 109 mA max Tx ICC), optical parameters (–9 to –1 dBm Tx power, –19 dBm Rx sensitivity), diagnostic interface compliance (SFF-8472), and MSA-compliant mechanical integration details for rapid system validation.
Technical Context
The AFBR-57L1APZ integrates an FP laser driver IC with internal monitor diode feedback for temperature- and voltage-compensated optical output, and a PIN/TIA receiver delivering LVPECL differential outputs with TTL LOS signaling per SFF-8074i. Its diagnostic monitoring uses a 2-wire SDA/SCL interface compliant with SFF-8472 Rev 11.3.
Transmitter operation is defined by IEEE 802.3z eye compliance, 227 ps total jitter (PRBS7), and extinction ratio ≥9 dB; receiver performance includes BER ≤1×10⁻¹² over OM1/OM4 2-km links, signal detect assert at –19.0 dBm, and deassert at –35 dBm - all guaranteed across the full –40°C to +85°C case temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 1.25 Gbaud - matches IEEE 802.3z Gigabit Ethernet line rate with PRBS7 jitter characterization. |
| Optical Wavelength | 1310 nm ±40 nm - FP laser center wavelength stable across –40°C to +85°C case temperature. |
| Transmission Distance | Up to 2 km on OM1 (62.5/125 μm) and OM4 (50/125 μm) multimode fiber - validated for BER ≤1×10⁻¹². |
| Supply Voltage | +3.3 V (3.1–3.5 V) - single rail powering separate VCCT (Tx) and VCCR (Rx) domains with independent ground planes. |
| Diagnostic Interface | SFF-8472-compliant 2-wire DMI - provides real-time readout of temperature (±3°C), Tx bias (±5 mA), Tx/Rx power (±3 dB). |
| Operating Temperature | –40°C to +85°C case temperature - electrical and optical specs fully guaranteed across this range. |
| Hot-Plug Sequencing | 3-stage pin contact order (ground → power → signal) - ensures ESD-safe insertion/removal without host downtime. |
Pinout & Package
The AFBR-57L1APZ uses the industry-standard SFP package (MSA-compliant) with LC duplex optical interface, 20-pin edge connector, and dimensions conforming to SFP MSA mechanical layout (Figure 6 in DS102). It supports hot-plug installation into any MSA-compliant SFP port.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 17, 20, VEET | Transmitter Ground | Common low-impedance return path for Tx circuitry; internally connected to other VEET pins. |
| 3, TxDisable | Transmitter Disable Control | Active-high logic input; disables laser output when high or open, reducing power and enabling safe hot-swap. |
| 4, MOD-DEF2 (SDA) | DMI Serial Data | Open-drain bidirectional data line for SFF-8472 EEPROM read/write; requires 4.7–10 kΩ pull-up on host board. |
| 5, MOD-DEF1 (SCL) | DMI Serial Clock | Input clock for 2-wire DMI interface; synchronized with SDA for real-time diagnostics access. |
| 6, MOD-DEF0 | Module Presence Indicator | Internally grounded to signal module insertion to host controller via I²C presence detection. |
| 8, LOS | Loss of Signal Output | Open-collector TTL output (3.3 V compatible); asserts high when received optical power falls below –19 dBm. |
| 9–11, 14, VEER | Receiver Ground | Dedicated low-noise return path for Rx analog front-end; isolated from VEET to minimize crosstalk. |
| 12–13, RD−/RD+ | Differential Receiver Output | LVPECL-compatible AC-coupled outputs; internally terminated, requiring only 100 Ω differential load at SERDES. |
| 15, VCCR | Receiver Power Supply | +3.3 V supply for receiver section; decoupled with 0.1 μF and 10 μF capacitors per MSA recommendations. |
| 16, VCCT | Transmitter Power Supply | +3.3 V supply for transmitter section; independently regulated to maintain laser bias stability under load variation. |
| 18–19, TD−/TD+ | Differential Transmitter Input | AC-coupled LVPECL inputs; 100 Ω differential termination inside module eliminates need for external termination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SFP transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-57E1APZ | Same form factor and DMI capability but uses 850-nm VCSEL for shorter reach (550 m on OM4); lower power consumption (max 95 mA vs. 109 mA). | Optimized for data center rack-to-rack links rather than 2-km industrial spans; not suitable for legacy OM1 or long-haul substation fiber. | Select AFBR-57E1APZ only when deploying on OM4 fiber ≤550 m and lower power budget is critical. |
| FTLX1471D3BCL | 1310-nm FP SFP with identical 2-km OM1/OM4 reach and SFF-8472 DMI, but rated for 0°C to +70°C commercial temp range (vs. –40°C to +85°C industrial). | Lacks extended temperature qualification - unsuitable for outdoor or unheated industrial cabinets where ambient exceeds 70°C or drops below 0°C. | Choose FTLX1471D3BCL only for controlled indoor telecom or enterprise environments with stable thermal profiles. |
Compared with AFBR-57L1APZ, AFBR-57E1APZ trades reach for lower power and shorter wavelength compatibility, while FTLX1471D3BCL sacrifices industrial temperature range for cost-sensitive commercial deployments - making AFBR-57L1APZ uniquely suited for harsh-environment 2-km multimode applications.

FAQ
What is the maximum supported fiber distance for AFBR-57L1APZ?
The AFBR-57L1APZ supports up to 2 km on both OM1 (62.5/125 μm) and OM4 (50/125 μm) multimode fiber, with BER ≤1×10⁻¹² validated per IEEE 802.3z specifications. This reach is achieved using its 1310-nm FP laser and PIN/TIA receiver pair optimized for modal dispersion tolerance in legacy and modern multimode infrastructures.
Does AFBR-57L1APZ support digital diagnostics, and how is it accessed?
Yes, AFBR-57L1APZ implements full SFF-8472 Rev 11.3 diagnostic monitoring via a 2-wire serial interface (MOD-DEF1/SCL and MOD-DEF2/SDA). It provides real-time readings for temperature (±3°C), Tx bias current (±5 mA), Tx output power (±3 dB), and Rx input power (±3 dB), accessible through standard I²C commands to the onboard EEPROM.
What is the operating temperature range for AFBR-57L1APZ, and where is temperature measured?
The AFBR-57L1APZ operates from –40°C to +85°C case temperature, with all electrical and optical specifications guaranteed across this range. Temperature is measured internally at the transceiver housing surface using an integrated sensor, as defined in the datasheet's Recommended Operating Conditions table - not at the PCB or ambient air.
Can AFBR-57L1APZ be hot-plugged into an active SFP port, and what safeguards enable this?
Yes, AFBR-57L1APZ supports true hot-plug operation in any MSA-compliant SFP port, even while the host system is powered and running. This is enabled by 3-stage pin sequencing (ground → power → signal), EMI-shielded housing contact, and controlled ESD tolerance (2 kV HBM on pins, 8 kV contact on LC receptacle), preventing bus contention or damage during insertion/removal.
What laser safety classification applies to AFBR-57L1APZ, and what standard does it meet?
AFBR-57L1APZ is certified as a Class 1 laser product per EN 60825-1:2014, verified under single-fault conditions by Broadcom.
