100G QSFP28 BiDi Transceiver for long distance single mode fiber links up to 20 km. Supports 100G full duplex transmission over one pair of SMF using bidirectional wavelengths 1271 nm TX and 1331 nm RX, and 1331 nm TX and 1271 nm RX. Uses LC duplex connector. Compliant with IEEE 802.3bm CAUI-4, QSFP28 MSA and SFF-8636 standards. Supports dual rate operation for 100G and backward compatible 40G BiDi modes. Typical TX optical power is from +0.5 dBm to +5 dBm. RX sensitivity is -10.5 dBm at pre-FEC BER of 5e-5. Power consumption is 4.5 W or less. Operating case temperature range is 0 C to 70 C. Includes Digital Diagnostics Monitoring DDM or DOM for real time measurement of TX power, RX power, module temperature, supply voltage and other key parameters. Compatible with Cisco platforms including Nexus 9300 and 9500 series, Catalyst 9000 series, ACI systems and NCS 5500. Also compatible with NVIDIA Mellanox SN2010, SN2410, SN2700, SN3700 and SN4600 switches.
