Irixi's 25G SFP28 LR optical Transceiver is well designed for 25GBASE-LR Ethernet interconnection, and links up to 10KM transmission distance over single-mode fiber (SMF). The module converts 25.78 Gbps electrical data into optical signal by a driver chipset and 1310nm Distributed Feedback Laser (DFB), then transmit through a single mode fiber for optical transmission. Oppositely, the receiver side where the module accepts the optical signal, and converts it into 25.78 Gbps electrical output by PIN Photodiode and Trans-Impedance Amplifier (TIA). The module features a hot-pluggable electrical interface, a duplex LC connector, and is designed to meet the SFF-8472, SFF-8431, IEEE 802.3cc 25GBASE-LR as well as the RoHS-6 Directive 2011/65/EU6, which is an ideal choice for the 25GBASE-LR Ethernet, CPRI optical transmission connectivity.
