Cisco SFP-10/25G-LR-S SFP-25G-LR-S Compatible Transceiver SFP28 25G 1310NM 10KM SMF for WAN

25GBASE-LR is a new generation architecture offering Enterprise 2.5 times more bandwidth than traditional 10GBASE for the cloud transition, enabling a highly efficient and powerful cloud connection between enterprise, cloud infrastructure and data center. 

For Enterprise, the Cisco Catalyst 9300 series Layer 3 switches are a leading stacking platform offering a variety of interfaces at the speed of 1G/10G/25G/40G/100G and meeting the evolving traffic of security, IoT, mobility and Cloud. 

Top-Trans SFP-10/25G-LR is a dual-rate 10G/25GBASE WAN transceiver equivalent to Cisco SFP-10G/25G-SR-S, interoperating with SFP28 ports uplinks of Cisco C9300X-12Y-A switches.  This SFP28 module uses a 1310NM DFB transmitter and PIN receivers and supports the transmission distance of 10KM over OS2 Singlemode Fiber. It offers high speed, low latency, low power consumption 25GBASE-LR connection fully compliant with IEEE 802.3by, IEEE 802.3cc, SFF-8402, SFF-8472, 21CFP-1040 LC#50 7/2001. It features build-in DDM/DOM via the I2C Interface to monitor the operating status.
