40Gbps DPSK Balanced Photo-receiver, U2T (Finisar) BPRV2123, Fiber Coupled, Differential Output
The Balanced photo-receiver module BPRV2123 is a differential front-end for 43Gbits/s DPSK-applications featuring high differential gain. The photo-receiver module contains two waveguide-integrated PIN photodiode (PD) and a single chip and limiting amplifier (LA) within one small form factor SMD-package. The Receiver is therefore well suited for 768/STM-256 system operation up to 43Gbits/s.
The DC output voltage can be monitored for OUTN and OUTP independently. For each amplifier path a threshold control at a linear amplification stage should be applied to ensure an optimized differential output signal.
An excellent electrical and optical phase propagation is achieved by a total skew of lower than 2ps between the balanced signal paths.
