This Juniper Networks EX-XFP-10GE-ER compatible XFP transceiver provides 10GBase-ER throughput up to 40km over single-mode fiber (SMF) at a wavelength of 1550nm using a LC connector. It is guaranteed to be 100% compatible with the equivalent Juniper Networks 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.
