Product details
Overview
HFBR-57E0PZ from Broadcom (formerly Avago) is a Small Form Factor Pluggable (SFP) multimode fiber transceiver for SONET OC-3/SDH STM-1 and Fast Ethernet physical layers, featuring a 1300 nm InGaAsP LED transmitter and InGaAs PIN photodiode receiver, +3.3 V single-supply operation, LC duplex optical interface, and -40 °C to +85 °C industrial temperature range.
For engineers reviewing the HFBR-57E0PZ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical interface timing (RD+/RD−, TD+/TD−), optical performance (−19 dBm min Tx power, −31 dBm min Rx sensitivity), LOS logic behavior (+3.3 V TTL open-collector), SFP MSA compliance, and thermal operating envelope - all critical for ATM switch, FDDI backbone, and legacy enterprise fiber link design.
Technical Context
The HFBR-57E0PZ implements a fully integrated SFP-compliant optical transceiver architecture with separate transmitter and receiver signal chains. Its LED driver IC accepts differential PECL inputs referenced to +3.3 V and drives a 1300 nm InGaAsP LED; the receiver uses an InGaAs PIN photodiode coupled to a transimpedance preamplifier and quantizer IC delivering squelch-enabled PECL-compatible differential outputs.
It supports dual-standard operation: SONET OC-3 (155.52 MBd) and Fast Ethernet (125 MBd), with distinct jitter specifications per standard (e.g., 0.25–1.2 ns p-p systematic jitter for OC-3; 0.20–0.6 ns p-p DCD for FE). The module includes EEPROM-based serial ID per SFP MSA, 3-stage hot-plug pin sequencing (GND → VCC → signal), and integrated ac-coupling and termination for both TX and RX paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Wavelength | 1270–1380 nm center wavelength; enables compatibility with 62.5/125 µm and 50/125 µm multimode fiber per IEEE 802.3u and ITU-T G.957. |
| Transmit Optical Power (BOL) | −19 dBm avg (62.5/125 µm); sufficient for ≥2 km OC-3 links with margin against 1 dB LED aging and connector/splice losses. |
| Receiver Sensitivity (BER ≤1×10⁻¹⁰) | −31 dBm avg at eye center (OC-3); ensures reliable detection under worst-case jitter and inter-symbol interference per FDDI PMD Annex A.5. |
| Data Interface | Differential PECL-compatible I/O (TD+/TD−, RD+/RD−) with internal 100 Ω termination and ac-coupling; eliminates external capacitors on host board. |
| Loss of Signal (LOS) | +3.3 V TTL open-collector output; asserts high when received optical power falls below −33 dBm (OC-3), with 1.5 dB hysteresis to prevent chatter. |
| Supply Voltage | +3.3 V ±10% (2.97–3.63 V); supports single-rail system design and meets SFP MSA power envelope (max 230 mA total). |
| Operating Temperature | −40 °C to +85 °C case temperature; validated for industrial-grade deployment in telecom infrastructure and harsh-environment switches. |
Pinout & Package
HFBR-57E0PZ uses the industry-standard SFP mechanical package (55.2 mm × 13.4 mm × 8.5 mm) with integral LC duplex optical interface and 20-pin edge-card electrical interface compliant with SFP MSA Rev. 4.1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 17, 20 | VEET | Transmitter ground reference; provides low-impedance return path for LED driver and TX bias circuitry. |
| 3 | Tx Disable | Active-high disable control; pulls transmitter LED current to zero when logic high or floating, enabling dynamic power management. |
| 4, 5 | MOD-DEF2 / MOD-DEF1 | Two-wire serial ID interface (clock/data); connects to host EEPROM bus for plug-and-play identification per SFP MSA. |
| 6 | MOD-DEF0 | Module presence indicator; grounded internally to signal insertion to host controller during hot-plug event. |
| 8 | LOS | Open-collector loss-of-signal flag; requires external 4.7–10 kΩ pull-up to VCC; low = valid optical input, high = fault condition. |
| 9, 10, 11, 14 | VEER | Receiver ground reference; isolated from VEET to minimize crosstalk between TX and RX sections. |
| 12, 13 | RD− / RD+ | Differential PECL receiver outputs; internally ac-coupled and terminated; deliver 400–2000 mV p-p swing into 100 Ω differential load. |
| 15 | VCCR | +3.3 V receiver supply; decoupled via 10 µF + 0.1 µF per MSA guidelines to suppress noise coupling into analog front-end. |
| 16 | VCCT | +3.3 V transmitter supply; separate rail from VCCR to isolate digital switching noise from LED bias circuitry. |
| 18, 19 | TD+ / TD− | Differential PECL transmitter inputs; accept 400–1200 mV p-p swing; internal ac-coupling eliminates need for host-side blocking caps. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant SFP package | Meets EU Directive 2002/95/EC; enables global deployment without hazardous substance restrictions. |
| Integrated ac-coupling & termination | Eliminates 8 external capacitors and 4 resistors on host PCB, reducing BOM count and layout complexity. |
| Squelch-enabled receiver outputs | Forces RD+/RD− to stable PECL logic levels (high/low) during LOS assert, preventing metastability in downstream SerDes. |
| 3-stage hot-plug pin sequencing | Ensures safe insertion/removal: ground pins make contact first, then power, then signals - prevents ESD damage and supply glitches. |
| Class 1 eye safety certified | Complies with EN60825-1 and IEC 60825-1 under single-fault conditions; no user-accessible laser hazard. |

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 | Same optical/electrical specs but rated for 0 °C to +70 °C commercial temperature range; lacks extended-temp qualification. | Suitable for climate-controlled data centers and office LANs; not qualified for outdoor or industrial enclosures. | Select HFBR-57E0LZ only if ambient operating temperature remains within 0–70 °C and cost optimization is prioritized. |
| AFBR-57E5APZ | Successor part with identical SFP footprint and pinout; uses VCSEL instead of LED, delivering higher Tx power (−14 dBm) and lower jitter (0.15 ns p-p RJ). | Enables longer reach (>5 km) and improved BER margin in new designs; requires validation of VCSEL eye safety classification. | Choose AFBR-57E5APZ for new designs requiring extended link budget or tighter jitter compliance; HFBR-57E0PZ remains optimal for legacy LED-based systems. |
Compared with HFBR-57E0LZ, HFBR-57E0PZ adds industrial temperature resilience without changing footprint or firmware interface; versus AFBR-57E5APZ, it trades VCSEL performance for proven LED reliability and lower EMI in electrically noisy environments.

FAQ
What is the maximum supported link distance for HFBR-57E0PZ over 62.5/125 µm multimode fiber?
The HFBR-57E0PZ supports up to 2 km over 62.5/125 µm OM1 fiber at OC-3 rates, based on its −19 dBm minimum transmit power, −31 dBm receiver sensitivity, and 1 dB optical power budget margin for LED aging and connector losses. This aligns with IEEE 802.3u 100Base-FX and ITU-T G.957 STM-1 specifications.
Does HFBR-57E0PZ require external AC-coupling capacitors on the host board?
No, HFBR-57E0PZ integrates AC-coupling capacitors for both TD+/TD− and RD+/RD− paths. The module delivers fully ac-coupled, 100 Ω differential PECL signals, eliminating the need for four external 100 nF capacitors on the host PCB and simplifying layout per SFP MSA guidelines.
How does the Loss of Signal (LOS) output behave during fiber disconnect events?
The HFBR-57E0PZ LOS output is an open-collector +3.3 V TTL signal that goes high when received optical power drops below −33 dBm (OC-3) or −31 dBm (FE), with 1.5 dB hysteresis. Assert time is ≤350 µs; deassert time is ≤100 µs, ensuring rapid fault detection without false triggering from transient noise.
Is HFBR-57E0PZ compatible with SFP MSA Rev. 4.1 host ports?
Yes, HFBR-57E0PZ fully complies with SFP MSA Rev. 4.1, including mechanical dimensions, 20-pin edge-card interface, 3-stage hot-plug sequencing, two-wire serial ID (MOD-DEF0–2), and electrical signaling (PECL I/O, VCC/VCC T/VCC R rails). It operates without host firmware modification.
What is the optical spectral width specification for HFBR-57E0PZ, and why does it matter?
HFBR-57E0PZ has a spectral width of ≤147 nm FWHM (typical 63 nm RMS) at 1300 nm. This broad emission is inherent to its InGaAsP LED source and is optimized for modal dispersion tolerance in multimode fiber - unlike narrow-linewidth lasers, it avoids differential mode delay issues in legacy 62.5/125 µm installations.
