Broadcom AFBR Metal Fiber Optic Transmitter/Receiver

Broadcom AFBR-1555ARZ and AFBR-2555ARZ Reinforced Metal Fiber Optic Transmitter and Receiver for SERCOS Applications are standard digital interfaces for communication in industrial CNC applications. SERCOS is a European (EN 61491) and international standard (IEC 61491).

SERCOS is a European (EN 61491) and international standard (IEC 61491). The optical interface allows data rates of 2, 4, 8, and 16MBd. The devices have data transfer between numerical controls and drives via fiber-optic rings, with voltage isolation and noise immunity.

The Broadcom AFBR-1555ARZ and AFBR-2555ARZ comply with SERCOS specifications for optical characteristics and connector style and have guaranteed performance at 2, 4, 8, and 16MBd data rates.

AFBR-1555ARZ Transmitter

The AFBR-1555ARZ transmitter incorporates a 650nm LED within a reinforced metal housing. The high light output power enables the use of plastic optical fiber (POF) and Plastic Clad Silica (PCS).

The AFBR-1555ARZ can be operated up to 16MBd using a simple driver circuit.

The AFBR-1555ARZ is compatible with SMA connectors.

AFBR-2555ARZ Receiver

The AFBR-2555ARZ receiver consists of an IC with an integrated photodiode to produce a logic compatible output assembled into a reinforced metal housing. The receiver output is a push-pull stage compatible with TTL and CMOS logic.

The AFBR-2555ARZ fits together with SMA connectors.
