43 Gbit/s DPSK
Balanced Photoreceiver
Product Code: BPRV2123(A)
Product Description
The balanced photoreceiver module BPRV2123(A) is a differential front-end for 43 Gbit/s DPSK-applications featuring high differential gain of typically
2400 V/W and is available as AC- or DC-coupled version. The photoreceiver contains two waveguide-integrated pin-photodiodes (PD) on a single chip
and a limiting amplifier (LA) within one small form factor SMD-package. The limiting amplifier provides a differential output voltage swing of typ. 600 mV.
The receiver is therefore well suited for OC-768/STM-256 system operation up to 43 Gbit/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 5 ps between the balanced signal paths.
