Product details
Overview
HFBR-57E0APZ from Broadcom (formerly Avago) is a multimode fiber SFP transceiver implementing SONET OC-3/SDH STM-1 and 100Base-FX Fast Ethernet physical layers. It operates at 1300 nm using an InGaAsP LED transmitter and InGaAs PIN photodiode receiver, supports LC duplex interface, requires single +3.3 V supply, and delivers -15.7 dBm min optical output power with -31 dBm receiver sensitivity for 155.52 MBd operation.
For engineers reviewing the HFBR-57E0APZ datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated SFP pin mapping, confirmed OC-3/Fast Ethernet interoperability, real-world LOS threshold behavior, and peer-validated alternative transceivers meeting MSA-compliant multimode 1300 nm operation.
Technical Context
The HFBR-57E0APZ integrates a custom silicon LED driver IC converting differential PECL inputs (ECL-referenced to +3.3 V) into analog LED drive current, and a receiver chain comprising an InGaAs PIN photodiode, transimpedance preamplifier, and quantizer IC delivering squelch-enabled PECL-compatible differential outputs (RD+/RD−) plus +3.3 V TTL LOS signal. Its optical subassembly is optimized for 62.5/125 μm and 50/125 μm multimode fiber.
It complies fully with ATM Forum UNI SONET OC-3 multimode fiber PL, IEEE 802.3u 100Base-FX, and FDDI PMD optical performance requirements. The module implements MSA-defined serial ID via 2-wire EEPROM (AT24C01A-compatible), supports hot-plug insertion with 3-stage pin sequencing (ground → power → signal), and features internal AC coupling and termination for TD+/TD− and RD+/RD− interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SFP transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HFBR-57E0LZ | Commercial temperature range (0 °C to +70 °C); identical optical/electrical specs and pinout | Targeted for enterprise LANs and non-extended-temperature telecom access nodes | Select when ambient operating conditions remain within commercial grade and cost optimization is prioritized |
| AFBR-57E5APZ | Same form factor and LC interface but uses VCSEL instead of LED; higher output power (-12 dBm typ), lower jitter (RJ ≤0.3 ns) | Supports longer reach (≤2 km) and tighter jitter budgets in OC-3/STM-1 systems requiring enhanced signal integrity | Choose when upgrading legacy links needing improved margin or migrating toward VCSEL-based infrastructure roadmaps |
Compared with HFBR-57E0APZ, HFBR-57E0LZ offers identical functionality at lower cost for benign environments, while AFBR-57E5APZ trades LED reliability for VCSEL performance gains in jitter-critical or longer-reach deployments - neither is pin-compatible without host board validation due to differing drive characteristics and thermal profiles.

FAQ
What is the operating temperature range for HFBR-57E0APZ?
The HFBR-57E0APZ is rated for case operating temperatures from -40 °C to +85 °C, making it suitable for extended industrial and outdoor telecom infrastructure deployments. This range is validated per the Absolute Maximum Ratings and Recommended Operating Conditions tables in the official datasheet, with all optical and electrical specifications guaranteed across this span when supplied with 2.97–3.63 V.
Does HFBR-57E0APZ support hot-plug insertion?
Yes, HFBR-57E0APZ supports true hot-plug operation per the SFP Multi-Source Agreement. Its mechanical design and 3-stage pin sequencing (ground → power → signal) ensure safe insertion/removal while the host system is powered and operational. The LC connector shield makes initial EMI contact, and the module housing mitigates ESD damage risk during handling.
What optical fiber types does HFBR-57E0APZ support?
HFBR-57E0APZ is designed for use with standard multimode fiber: both 62.5/125 μm (NA = 0.275) and 50/125 μm (NA = 0.20). Its 1300 nm LED source and optical alignment are optimized for these core/cladding dimensions, delivering specified output power and receiver sensitivity per ITU-T G.957 and IEEE 802.3u requirements.
How is the Loss of Signal (LOS) function implemented in HFBR-57E0APZ?
The HFBR-57E0APZ implements LOS as an open-collector +3.3 V TTL output (pin 8) that goes high (>2.0 V) when received optical power drops below -31 dBm (OC-3) or -33 dBm (Fast Ethernet), indicating a definitive fault such as broken fiber or failed transmitter. It features 1.5 dB hysteresis to prevent oscillation near threshold and asserts within 350 μs of signal loss.
Is HFBR-57E0APZ RoHS compliant and eye-safe?
Yes, HFBR-57E0APZ is fully RoHS compliant per EU Directive 2002/95/EC and certified Class 1 eye safe per EN60825-1 (+A11) under both normal operation and single-fault conditions. Avago testing confirms no hazardous optical emission levels are possible, eliminating the need for external safety interlocks in end-user equipment.
