Ascent’s SFPP28 10/25G LR transceiver provides 10/25GBASE-LR throughput up to 10km over single mode fiber (SMF) using a wavelength of 1310nm via an LC duplex connector. It provides connectivity option for 25G Ethernet, 10G Ethernet and data center. It is fully compliant with the SFP28 MSA, SFF-8472, SFF-8402, SFF-8432 and applicable portions of SFF-8431 standard. An integrated fiber optic transceiver that provides a high-speed serial link at signaling rates up to 25.78 Gb/s. The module complies with SFF-8431 and SFF-8472 standards. It is suitable for 10/25G Ethernet and CPRI 10 applications and has a transmission distance of up to 10 km on single-mode fibers. The transceiver features a metal enclosure for lower EMI. It utilizes a 2-wire interface that is compliant with the serial communication protocol as defined in the SFP+ MSA. It also provides a unique integrated digital diagnostic monitoring interface, allowing for real-time access to device operating parameters. This module is also hot-pluggable.
