Description

This transceiver provides 100GBase-BX throughput up to 80km over single-mode fiber (SMF) using wavelengths of 1273.54, 1277.89, 1282.26, 1286.66nm- TX/1295.56, 1300.05, 1304.58, 1309.14nm-RX(1295.56, 1300.05, 1304.58, 1309.14nm- TX/1273.54, 1277.89, 1282.26, 1286.66nm-RX) via an LC connector. This bidirectional unit must be used with another transceiver or network appliance of complimenting wavelengths. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP28 MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as 100G Ethernet, data center, and storage area networks applications.
