Product details
Overview
The AFBR-59E5APZ-HT from Broadcom is a multimode fiber SFF transceiver implementing 100BASE-FX Fast Ethernet over 50/125-µm and 62.5/125-µm fiber, featuring a 1310-nm LED transmitter, PIN photodiode receiver, differential LVPECL I/O, and –40°C to +95°C industrial operating range.
For engineers reviewing the AFBR-59E5APZ-HT datasheet, pinout, applications, or equivalent options, key selection criteria include optical power budget (–20 dBm min TX / –31 dBm sensitivity), AC-coupled LVPECL interface compliance, LC duplex connector integration, and signal detect (SD) with hysteresis for link monitoring in harsh environments.
Technical Context
This transceiver implements a fully integrated 2×5 DIP-form-factor optical subassembly with separate TX and RX ICs: the transmitter uses an integrated LVPECL-to-LED driver IC controlling a high-reliability 1310-nm LED, while the receiver integrates a PIN photodiode with transimpedance and post-amplifier in a single die delivering squelched LVPECL outputs.
Signal integrity is maintained via AC-coupled differential LVPECL I/O (TD±, RD±), on-chip SD logic with programmable hysteresis (0.5–2 dB), and Tx-disable functionality with internal pull-down - all powered from a single +3.3 V supply across the full industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multimode Fast Ethernet transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-59E5APZ | Same optical/electrical specs but rated for 0°C to +70°C commercial temperature range | Limited to indoor, climate-controlled control rooms; not qualified for outdoor substations or HVDC valve halls | Select AFBR-59E5APZ-HT when ambient case temperature exceeds +70°C or falls below 0°C |
| AFBR-59E5Z | Identical SFF package and LC interface but uses VCSEL transmitter (850 nm) optimized for OM3/OM4 fiber | Higher bandwidth but shorter reach on 62.5/125 µm fiber; incompatible with legacy 100BASE-FX plant using 1310 nm optics | Choose AFBR-59E5Z only when upgrading to laser-optimized fiber and higher-speed protocols beyond Fast Ethernet |
Compared with AFBR-59E5APZ and AFBR-59E5Z, the AFBR-59E5APZ-HT uniquely combines extended temperature operation, 1310-nm LED compatibility with installed 62.5/125-µm fiber plants, and signal detect timing optimized for substation protection schemes - making it the sole option for retrofitting legacy utility infrastructure.

FAQ
What is the maximum supported fiber link length for AFBR-59E5APZ-HT?
The AFBR-59E5APZ-HT supports up to 2 km over 62.5/125-µm multimode fiber and 500 m over 50/125-µm fiber, based on its optical power budget: –20 dBm minimum transmit power and –31 dBm receiver sensitivity, assuming standard connector and splice losses. Link length must be verified against actual plant loss measurements including margin for aging.
Does AFBR-59E5APZ-HT support hot-plug operation?
Yes, AFBR-59E5APZ-HT supports hot-plug operation via its Signal Detect (SD) output and Tx-disable pin. When inserted into a live backplane, SD asserts within 100 µs of optical input presence, and the transmitter remains disabled until host firmware enables it via Pin 8 - preventing spurious emissions during insertion.
What is the recommended termination for AFBR-59E5APZ-HT LVPECL signals?
The AFBR-59E5APZ-HT requires 100 Ω differential termination for both TD± and RD± pairs, implemented as two 50 Ω resistors to VCC–2 V. AC coupling capacitors (0.1 µF) must be placed adjacent to the transceiver pins, and the recommended application circuit (Figure 2 in DS101) includes 2.7 kΩ/4.3 kΩ Thevenin biasing for optimal common-mode voltage.
How is ESD protection implemented on AFBR-59E5APZ-HT?
AFBR-59E5APZ-HT provides dual-path ESD protection: ±2000 V HBM on all 10 electrical pins per JS-001-2017, and 9 kV contact / 15 kV air discharge tolerance on the LC receptacle per IEC 61000-4-2. The metal housing is grounded to chassis, and protective process plugs shield the optical interface during wave soldering and handling.
Can AFBR-59E5APZ-HT be used with single-mode fiber?
No, AFBR-59E5APZ-HT is specified exclusively for multimode fiber (50/125-µm and 62.5/125-µm). Its 1310-nm LED source has a large emission area and numerical aperture mismatched to single-mode core geometry, resulting in excessive insertion loss and modal instability - it does not meet IEEE 802.3u 100BASE-FX requirements on SMF.
