Technical Specs Summary

Detailed Product Description

Product Overview

The GIGAC DT-1529Z is a 650nm analog optical transmitter in Avago Versatile Link 4-pin package format, designed as a full-compatibility replacement for the Avago (Broadcom) AFBR-1529Z. It uses a 650nm LED source in a housing optimized for efficient optical coupling into 1mm Polymer Optical Fiber (POF) and 200μm Plastic-Clad Silica (PCS) fiber.

Operating at data rates from DC to 10MBd, the DT-1529Z supports link distances up to 50m over 1mm POF and up to 200m over 200μm PCS — significantly extending the reach available from 1mm POF-only systems. It is designed to interoperate with Avago HFBR-25xxZ, AFBR-25xxZ, and AFBR-26xxZ receiver modules for complete optical link deployment.

The Versatile Link 4-pin package is a 4-pin device packed in Versatile Link housing using the same pad layout as a standard 8-pin DIP. This housing is made from flame-retardant VALOX1 material (UL 94 V-0) with a snap-action dust-resistant seal. Versatile Link components can be horizontally stacked (N-Plexed together) to minimize board space and provide dual connections with simplex or duplex connectors.

  Technical Advantages

10MBd at 650nm — Faster Than AFBR-1531CZ (5MBd at 520nm)

At 10MBd, the DT-1529Z/AFBR-1529Z operates at twice the data rate of the 520nm AFBR-1531CZ series. This higher speed covers industrial serial protocols that exceed the 5MBd capability of the lower-speed 520nm POF systems, including faster RS-485 multi-drop links, PROFIBUS at higher baud rates, and board-to-board control data links within densely interconnected industrial control systems.

Dual Fiber Support: 1mm POF and 200μm PCS

Unlike 520nm systems limited to 1mm POF, the AFBR-1529Z/DT-1529Z also supports 200μm PCS (Plastic-Clad Silica) fiber, extending maximum link distance from 50m (POF) to 200m (PCS) within the same module design. PCS fiber offers lower attenuation than pure POF at 650nm, enabling longer runs where 1mm POF reach is insufficient but glass MMF infrastructure is not available or cost-justified.

Versatile Link N-Plexing — Space-Efficient Multi-Channel Assembly

The Versatile Link housing system allows multiple transmitter or receiver modules to be horizontally interlocked (N-Plexed) side-by-side on the PCB without individual connector housings per channel. This dramatically reduces the PCB footprint for multi-channel fiber link applications — such as 4-channel or 8-channel parallel data links — compared to discrete individual module assemblies. Stacked assemblies can be disengaged without damage to individual units.

Auto-Insertable Standard DIP Footprint — PCB Integration

The Versatile Link 4-pin module uses the same pad layout as a standard 8-pin dual-inline package (DIP), making it auto-insertable in standard through-hole PCB assembly equipment. This eliminates manual placement requirements and integrates seamlessly into high-volume PCB production lines using automated insertion machines.

Isolation Applications — Ground Loop Elimination and HV Isolation

Fiber optic transmission provides complete galvanic isolation between the transmitter and receiver ground references. This makes the DT-1529Z particularly effective in applications where ground loop noise, voltage transient susceptibility, or high-voltage isolation barriers must be implemented in serial data links — common requirements in motor drive control, power supply monitoring, and high-potential measurement circuits.

Fiber Type and Distance Reference

Select fiber type based on required link distance.

Both fiber types use 650nm wavelength and the same DT-1529Z transmitter. Select receiver from HFBR-25xxZ, AFBR-25xxZ, or AFBR-26xxZ series to match your fiber type and distance.

Compatible Receiver Reference

The DT-1529Z transmitter is designed to interoperate with the following Avago receiver families and their GIGAC equivalents.

Contact our technical team for the full receiver model list within each family. Specify your fiber type (POF or PCS) and required distance when selecting the receiver.

Typical Applications

Compatibility and Deployment

The DT-1529Z is a pin-compatible replacement for the Avago AFBR-1529Z using the same Versatile Link 4-pin footprint. It installs directly in any PCB or housing designed for the OEM part. Compatible with 1mm POF and 200μm PCS fiber types. Pair with HFBR-25xxZ, AFBR-25xxZ, or AFBR-26xxZ series receivers for complete links.

For assembly: leave the optical port plug in place during wave soldering to prevent contamination. Use only non-halogenated water-soluble flux (0% chloride content). Versatile Link modules are moisture-sensitive — handle per shipping tube labeling; a pre-solder baking step may be required after extended air exposure. Contact our technical team for receiver module selection, volume pricing, or application circuit guidance.

FAQ Module 

Q: What is the Versatile Link package system?

A: Versatile Link is Avago's proprietary packaging system for short-distance plastic optical fiber (POF) and PCS fiber transmitters and receivers. It uses a 4-pin module in a housing made from UL 94 V-0 flame-retardant VALOX1 material with a dust-resistant snap seal. Key features include N-Plexing (horizontal stacking of multiple modules), auto-insertability in standard 8-pin DIP pad layouts, and standardized color coding (gray=TX, black=RX) for installation identification.

Q: What is N-Plexing (stacking) and what does it enable?

A: N-Plexing refers to horizontally interlocking (stacking) multiple Versatile Link modules side-by-side on a PCB. By sliding the L-bracket body of one module into the L-slot of the adjacent module, they lock together and can be aligned with a straight edge. This minimizes PCB footprint for multi-channel fiber applications (e.g., 4-channel or 8-channel parallel links) compared to discrete individual housings. Stacked assemblies can be disengaged without damage.

Q: What is the difference between 1mm POF and 200μm PCS fiber?

A: Both are plastic-based fibers, but with different core structures. 1mm POF has an all-plastic PMMA core; 200μm PCS (Plastic-Clad Silica) has a glass silica core with a plastic cladding. PCS has lower optical attenuation at 650nm, enabling longer transmission distances (up to 200m vs 50m for 1mm POF). Use 1mm POF for shorter, easier-to-install runs; use 200μm PCS where longer reach is required without switching to full glass MMF.

Q: What receiver modules are compatible with the DT-1529Z?

A: The DT-1529Z is designed to interoperate with Avago HFBR-25xxZ, AFBR-25xxZ, and AFBR-26xxZ series receivers (and their GIGAC DT-series equivalents). Select the receiver based on your fiber type (POF or PCS) and required distance. Contact our technical team for the full receiver model list and selection guidance for your specific application.

Q: Why must only water-soluble non-halogenated flux be used for Versatile Link soldering?

A: The Versatile Link housing material and optical components are sensitive to the residues left by rosin-based (no-clean) fluxes, which can contaminate the optical coupling interface or degrade the housing material over time. Non-halogenated water-soluble flux (0% chloride) can be fully rinsed away after wave soldering, leaving no residue. The optical port plug must be kept in place during soldering to prevent solder or flux ingress into the fiber port.

Q: How does this transmitter provide electrical isolation?

A: Optical fiber transmits data using light — there is no electrical conductor connecting the transmitter and receiver. This provides complete galvanic isolation between the transmitter ground and the receiver ground, breaking ground loops, blocking high-voltage transients, and eliminating the common-mode voltage differences that corrupt RS-232/RS-485 signals in noisy industrial environments.

Ordering Information

Transmitter only (DT-1529Z, gray). Order the corresponding receiver from the HFBR-25xxZ/AFBR-25xxZ/AFBR-26xxZ series for a complete link. Specify fiber type (1mm POF or 200μm PCS) and required distance when selecting receiver.

Receiver modules must be ordered separately. Contact our technical sales team for receiver model selection, full Versatile Link series catalog, N-Plexing assembly guidance, and volume pricing.
