The LDR-12-M is a 12 Gb/s bandwidth high gain, lightwave digital receiver module designed for OC-192, DWDM, and Bit Error Rate Testing (BERT) of a digital optical link. The LDR-12-M is an O/E converter with post/limiting amplifier module designed for use in receivers of STM-64/OC-192 and STM-64/OC-192 with Forward Error Correction (FEC) (10.664 Gb/s) optical transmission systems. This module consists of a PIN photodiode, pre- amplifier, post-amplifier, and limiting amplifier. At the optical input level of -17 dBm, LDR-12-M provides an output level of 1.0Vp-p. This high output level makes it ideal for BERT testing.
