Specifications

40Gbps DPSK Balanced Photo-receiver, U2T (Finisar) BPRV2125/ BPRV2125A, Fiber Coupled, Differential Output
the Balanced photo-receiver module BPRV2125A 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 DPSK and DQPSK applications at 40G and 100G with rates between 20G and 56GBaud.
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 5ps between the balanced signal paths.
