Technical Specs Summary

Detailed Product Description

Product Overview

The GIGAC AFBR-59E4APZ-HT Compatible SFF Optical Module is custom-designed by GIGAC Technology for full drop-in compatibility with the Broadcom® (formerly Avago) AFBR-59E4APZ-HT. It provides system designers with a reliable, cost-effective, and fully qualified alternative for implementing Fast Ethernet over multimode fiber in both new designs and existing equipment.

The module uses the industry-standard 2×5 dual inline package (DIP) format with an LC fiber connector interface. The transmitter uses a 1310nm light-emitting diode (LED) driven by an integrated circuit that converts LVPECL differential signals to analog LED drive current. The receiver employs an Indium Gallium Arsenide (InGaAs) PIN photodiode coupled to a transimpedance preamplifier IC and quantizer IC for pulse shaping on the data output.

Both data output and signal detect output are LVPECL compatible. The module is compatible with wave soldering and aqueous cleaning processes, meeting the requirements of large-scale PCB manufacturing environments. It is manufactured in an ISO 9001-certified facility, and complies with IEEE 802.3u 100BASE-FX optical performance specifications and RoHS environmental regulations.

Technical Advantages

Verified Drop-In Compatibility with AFBR-59E4APZ-HT

GIGAC's compatible module is engineered and validated against the full Broadcom® AFBR-59E4APZ-HT pin configuration, optical output/input specifications, electrical interface, and package dimensions. It can be substituted in existing PCB designs without any modification to the host board layout, firmware, or optical connector assembly — reducing qualification effort for equipment OEMs adopting a multi-source procurement strategy.

InGaAs PIN Receiver — Superior Sensitivity vs Standard GaAs

The InGaAs (Indium Gallium Arsenide) PIN photodiode provides superior responsivity at 1310nm compared to standard GaAs photodiodes — resulting in better receiver sensitivity and larger link budget margin for the same fiber type and distance. This is particularly relevant for 50/125μm multimode fiber applications where the launch power from a 1310nm LED is inherently lower than laser-based transmitters.

Extended Temperature: –40°C to +95°C

The operating temperature range of –40°C to +95°C exceeds the standard industrial specification of –40°C to +85°C by 10°C on the upper end. This additional thermal headroom is significant in dense board assemblies, industrial control cabinets with elevated ambient temperatures, and telecom outdoor equipment where case temperatures can approach +90°C in direct sunlight or poorly ventilated enclosures.

Wave Solder + Aqueous Wash Process Compatible

Compatibility with standard wave soldering and aqueous cleaning processes allows the module to be integrated into high-volume PCB production lines without process exceptions, hand soldering, or special handling requirements. This is a direct cost advantage in large-scale manufacturing environments where automated wave solder assembly is the standard PCB production method.

ISO 9001 Manufacturing Quality System

Production in an ISO 9001-certified facility provides documented quality management, controlled process parameters, and lot traceability — requirements increasingly specified in enterprise OEM and telecom procurement contracts for mission-critical optical components. This distinguishes the GIGAC compatible module from non-certified alternatives that may not maintain consistent process control across production lots.

Multi-Source 2×5 DIP Package

The 2×5 DIP package format is a widely adopted multi-source standard with multiple qualified suppliers. This reduces supply chain risk for equipment OEMs who need second-source qualification without PCB redesign, and provides procurement leverage through competitive multi-source pricing.

Typical Applications

•        Fast Ethernet switches and routers requiring multimode fiber uplinks

•        Industrial Ethernet equipment with 100BASE-FX fiber interfaces

•        Enterprise LAN to fiber media conversion

•        AFBR-59E4APZ-HT replacement and second-source procurement

•        Data center 100Mbps legacy fiber infrastructure

•        Telecom access equipment Fast Ethernet fiber links

•        High-volume industrial PCB assembly using wave solder process

•        OEM equipment with existing AFBR-59E4APZ-HT footprint needing multi-source supply

Compatibility and Deployment

The module is a direct pin-compatible replacement for the Broadcom® AFBR-59E4APZ-HT using the same 2×5 DIP footprint. It installs in any board designed for the AFBR-59E4APZ-HT without PCB layout changes. The LC interface accepts standard fiber patch cords. Compatible with both 62.5/125μm (OM1) and 50/125μm (OM2) multimode fiber.
