Broadcom Inc. AFBR-1310Z Fiber Optic Transmitter for Multi GHz Analog Links AFBR-1310Z

The AFBR-1310Z is a compact, high performance, cost effective transmitter for multi GHz analog communication over single mode optical fiber. The transmitter incorporates a linear wide bandwidth InGaAsAl/InP Fabry-Perot laser packaged inside a TO-header, coupled to a single mode fiber pigtail terminated with a standard FC/PC connector, a monitor photodiode for closed loop operation, a 50 ohm input impedance linear RF amplifier and a bias network that allows to separately control the laser average output power. The transmitter operates at a nominal wavelength of 1310 nm. Access to RF input, electrical control signals I/Os and amplifier supply is through a flexible printed circuit board. The RF input is self biased and AC coupled, and thus does not require an external DC block. A suitable bracket is used to mount the transmitter onto a PCB or metal substrate. The high output power and conversion gain allow for a high splitting ratio in branched Passive Optical Networks.
