This Cisco QSFP-100G-LR4-S compatible QSFP28 transceiver provides 100GBase-LR4 throughput up to 10km over single-mode fiber (SMF) at the wavelength specified between 1270nm to 1330nm using a LC connector. It is guaranteed to be 100% compatible with the equivalent Cisco transceiver. This easy to install, hot swappable transceiver has been programmed, uniquely serialized and data-traffic and application tested to ensure that it will initialize and perform identically. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. All of the transceivers are Trade Agreements Act (TAA) compliant.
