QSFP-40G-ER4 Duplex LC 40GBASE-ER4 40km 40G QSFP+ ER4
The 40G QSFP ER4 optical transceiver integrates the transmit and receive path onto one . Four electric-absorption modulated lasers (DFBs) with1271, 1291,1311 and 1331 nmcenter wavelengths, whichmultiplexed/demutiplexed into a single-mode fiber through an industry-standard LC connector. Each data steam is recovered by a PIN photodetector and transimpedance amplifier, retimed, and passed on to an output driver.
