AFBR-59F2Z Datasheet 250-mbd Compact 650-nm Transceiver

Manufacturer: Broadcom

Overview: AFBR-59F2Z 250-MBd Compact 650-nm Transceiver for Data Communication over Polymer Optical Fiber (POF) Cables with a Bare Fiber Locking System Data Sheet Overview The Broadcom® AFBR-59F2Z transceiver provides system designers with the ability to support serial communication with baud rates of up to 250 MBd over 2.2-mm jacketed standard polymer optical fiber (POF). The innovative bare fiber locking mechanism of the transceiver allows connection of POF cable with a simple insertand-lock system eliminating the need for connectors. This facilitates fast installation and maintenance. The AFBR-59F2Z is Laser Class 1, lead-free and compliant with RoHS. The very compact design is similar to that of the well-known RJ-45 connector. The transmitter consists of a 650-nm LED, which is controlled by a fully integrated driver IC. The LED driver operates at 3.3V. It receives low-voltage differential signaling (LVDS) electrical input, and converts it into a modulated current driving the LED. LED and driver IC are packaged in an optical subassembly. The optimized lens system of the optical subassembly couples the emitted optical power very efficiently into 1-mm core POF cable. The receiver utilizes a fully integrated single chip solution that provides excellent immunity to EMI and fast transient dV/dt rejection. The receiver directly converts light to a digital LVDS output signal and operates at 3.3V nominal supply. The integrated receiver is packaged in an optical subassembly, which couples optical power efficiently from POF to the receiving PIN.

Key Features

  • an analog monitor output of the incoming optical signal. The monitor output provides an analog voltage proportional to the average optical input power. In absence of receiver optical input signal, the receiver is in low power sleep mode and the differential output signal is pulled to ground. The receiver wakes up, when a valid optical input signal is detected. Features.
  • Easy bare fiber termination solution for 2.2-mm jacket POF.
  • EMI/ EMC robust.
  • Link lengths up to 40m POF.
  • L.
