LDPF/LDPW/LDSF PINFET Optical Receiver Modules

850, 1310, 1550 nm; Data Rate 1-350 Mb/s; Sensitivity -60—32 dBm; Responsivity 0.5-0.95 A/W; Min. Bandwidth 1-250 MHz; Output Impedance 10 Ω

With the LDPF/LDPW/LDSF PINFET series, OSI LaserDiode provides an excellent solution for optical receiver systems that require both high sensitivity and wide dynamic range. Applications include telecommunication line-terminating equipment or repeaters and optical sensor systems.

The PINFET optical receiver modules’ package offers high reliability which satisfies Telcordia specifications. The term “PINFET” (p-intrinsic-n, field-effect transistor) indicates the integration of a PIN photodiode and a discrete, high-performance transimpedance amplifier stage. Light is coupled into the detector stage through a multi mode (MM) optical fiber pigtail, which allows excellent coupling with either single mode (SM) or multi mode (MM) fiber systems.
