40GBASE-ZR4-Lite 40G 60km QSFP+

The HILINK 40G QSFP+ 60km optical transceiver integrates the transmit and receive path onto one module. Four electric-absorption modulated lasers (DFBs) with 1270~1330nm center wavelengths, which multiplexed/demutiplexed into a single-mode fiber through an industry-standard LC connector. Each data steam is recovered by a APD photodetector and transimpedance amplifier, retimed, and passed on to an output driver.
