Broadcom Inc. AFBR-2310Z Fiber Optic Receiver for Multi GHz Analog Links AFBR-2310Z

The AFBR-2310Z is a compact, high performance, cost effective receiver for multi GHz analog communication over single mode optical fiber. The receiver incorporates a wide bandwidth, low dark current InGaAs/InP PIN photodiode packaged inside a TO-header, together with a high performance E-pHEMT RF amplifier and its bias network. A receptacle designed according to the CEI/IEC 61754-13 standard allows coupling of the optical signal by means of a FC fiber patchcord. The receiver is optimized for operation at 1310 nm and 1550 nm but may be used over a wide wavelength range ranging from 850 nm to 1600 nm, with reduced performance. The amplifier low noise figure and PIN high responsivity allow for a high sensitivity and thus a high splitting ratio in branched Passive Optical Networks. Access to the RF output as well as bias of PIN and amplifier is through a flexible printed circuit board. The RF output requires external AC coupling. The receptacle is designed for assembly into a properly shaped aperture in the customer box wall or fixture.
