SFP 100G LR4 10km QSFP28+
100G LR4 10km QSFP28+
Product Overview:
HTF’100G QSFP28 LR4 optical Transceiver integrates receiver and transmitter path on one module. On the transmit side, four lanes of serial data streams are recovered, retimed, and passed to four laser drivers. The laser drivers control a 4-distributed Feedback Laser (DFB) with center wavelength of 1296 nm, 1300 nm, 1305 nm, and 1309 nm. The optical signals are multiplexed to a single-mode fiber through an industry-standard LC connector. In the receiving side, the four lanes of optical data streams are opticallydemultiplexed by the integrated optical de-multiplexer. Each data stream is recovered by a PINphoto-detectorand trans-impedance amplifier, retimed. This module features a hot-pluggable electrical interface, low-power consumption, and MDIO management interface. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA) and is compliant to IEEE 802.3bm.
