Optical Receivers improve link sensitivity by 3 dB or more.

Press Release Summary:




Models DSCR405 and DSCR405ER are 15 dB InGaAs balanced photoreceivers for wavelengths from 800 to 1,650 nm with over 14 and 20 GHz bandwidths, respectively. They are targeted at digital telecommunications markets using 10 and 20 Gbps with FEC and RZ formats. Units feature small form-factor fiber-pigtailed package that is hermetically sealed and built to GR-468 standards.



Original Press Release:



DSCR405 & DSCR405ER: Balanced Photoreceivers with 14 or 20 GHz Bandwidth



Balanced optical receivers manufactured by Discovery Semiconductors Inc. have been demonstrated to improve link sensitivity by 3 dB or more in applications such as DPSK, differential phase shift keying, and DQPSK, differential quadrature phase shift keying. In DPSK detection the phase of the optical signal is compared with a one bit delayed version of bit stream after passing through an optical interlever. The advantage versus OOK modulation lies in the 100% duty cycle possible with balanced detection.

Discovery offers two InGaAs balanced receivers with bandwidths of 14 and 20 GHz, the models DSCR405 and DSCR405ER respectively. These are targeted at digital telecommunications markets using 10 and 20 Gbps with FEC and RZ formats.
