10 Gb/s Digital Receiver with Clock Recovery (LRD-10-CLK-M)

Data Sheet

Product Overview

The Optilab LRD-10-CLK-M is a 10 Gb/s bandwidth high gain, lightwave digital receiver module with a 10 Gb/s clock recovery circuit, designed for OC-192, DWDM, and Bit Error Rate Testing (BERT) of a digital optical link. The LRD-10-CLK-M is an O/E converter with post/limiting amplifier module designed for use in receivers of STM-64/OC-192 (9.953 Gb/s) and STM-64/OC-192 with Forward Error Correction (FEC) (10.664 Gb/s) optical transmission systems. This cost-effective module consists of a PIN photodiode, pre-amplifier, post-amplifier, and limiting amplifier. The built-in clock recovery circuit has a separate 10 Gb/s clock recovery output, and at the optical input level of -17 dBm it provides an output level of 1.0 Vp-p.
