Shenzhen Mingjiada Electronics Co., Ltd. supplies the Broadcom AFBR-5FC85Z 50Mb Flexible Link fibre optic transceiver with an LC interface.

The Broadcom AFBR-5FC85Z is a highly adaptable and stable 50Mb Flexible Link fibre optic transceiver equipped with a standard LC fibre optic interface, specifically designed for low-to-medium speed industrial communication, device interconnection and short-distance fibre optic transmission applications. The product integrates optical transmission and reception functions into a single unit, combining a lightweight design, strong environmental adaptability and flexible networking capabilities. It is perfectly suited to short-distance Plastic Optical Fibre (POF) transmission systems, making it the preferred core component for small and medium-sized optical-electrical signal conversion and fibre-optic interconnection of industrial equipment.

I. AFBR-5FC85Z Core Specifications and Transmission Performance

The AFBR-5FC85Z transceiver achieves a core transmission rate of up to 50 Mbps (50 Mb), supporting wide-band signal transmission from DC to 50 Mbps. It reliably handles various medium- and low-speed digital communication signals without signal distortion or packet loss, balancing transmission efficiency with stability to suit the vast majority of non-high-speed industrial and commercial fibre-optic interconnection scenarios. Compared to traditional low-speed transceivers, it offers greater bandwidth redundancy and is compatible with multiple protocol signal transmissions, significantly enhancing adaptability.

In terms of transmission medium compatibility, the AFBR-5FC85Z is designed for transmission via 1mm-diameter plastic optical fibre (POF). Paired with a standard operating wavelength of 650nm, it features low optical signal transmission loss and strong interference resistance, with short-distance transmission stability far exceeding that of standard copper cable transmission. The device’s operating voltage is compatible with standard industrial 6V power supply systems, ensuring strong power supply compatibility. It can be directly embedded into various industrial control devices and communication terminals without the need for additional power conversion modules, thereby reducing equipment retrofitting and networking costs.

Temperature adaptability is one of the core advantages of the AFBR-5FC85Z. With an operating temperature range of -40°C to +85°C, it can comfortably handle harsh conditions such as extreme cold, high heat, enclosed equipment compartments and outdoor utility cabinets, completely eliminating the constraints of ambient temperature on communication transmission and meeting the requirements for industrial-grade, round-the-clock, uninterrupted operation. Furthermore, the product features compliance with humidity protection standards, making it suitable for damp and dusty industrial environments, whilst offering excellent resistance to environmental interference.

II. Design Advantages of the AFBR-5FC85Z LC Interface

The AFBR-5FC85Z comes standard with an LC fibre optic interface, utilising a modular latch structure developed by Bell Labs. The pin-to-sleeve dimension is just 1.25 mm, which is half the size of traditional SC and FC interfaces. The compact interface design significantly enhances port integration density, enabling high-density fibre optic cabling and networking, and meeting the port layout requirements of compact devices, small switches and embedded terminals.

The LC interface offers convenient insertion and removal, secure locking and anti-loosening features. Insertion and removal operations are simple and effortless, resulting in higher efficiency for manual cabling and equipment maintenance; The high mating precision of the interface minimises the risk of poor contact or signal interruptions during long-term operation, effectively preventing communication failures caused by equipment vibration or cable strain. Furthermore, the standardised LC interface offers exceptional versatility, being compatible with mainstream LC connectors, plastic optical fibres and multimode fibre cables available on the market. This ensures convenient procurement of accessories and maximises network compatibility.

III. Flexible Link Networking Features of the AFBR-5FC85Z

As a fibre optic transceiver designed for flexible link networking, the AFBR-5FC85Z breaks free from the limitations of traditional fixed networking modes. It supports various topologies, including flexible point-to-point networking and short-range multi-point interconnection, catering to diverse device interconnection requirements. Whether for single-device optical-to-electrical conversion, multi-device daisy-chain networking, or fibre expansion in small local area networks, it adapts rapidly, offering exceptional networking flexibility.

The AFBR-5FC85Z features an integrated design, with the transmitter and receiver highly integrated. It is compact in size and has extremely low power consumption, enabling it to operate independently without the need for complex peripheral circuitry. It can be directly embedded within industrial control motherboards, smart terminals, and communication equipment, without occupying any extra space. It also supports stable full-duplex communication, with synchronised signal transmission and reception free from conflicts, ensuring smooth link transmission. This meets the real-time data transmission requirements of scenarios such as industrial control, smart devices and security communications.
