25G DWDM SFP28 Fiber Optic Transceiver Ch21-Ch60 SMF 10KM Multi - Rate Supported
25G DWDM SFP28 Fiber Optic Transceiver Ch21 to Ch60 SMF 10KM Multi-rate Supported
Description
25G DWDM SFP28 LR transceiver is designed for 25G Ethernet and CPRI/eCPRI links reach up to 10km over Single-Mode Fiber (SMF). It is for duplex optical data communications support up to 25.78Gb/s. The SFP28 DWDM transceiver is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has built-in clock and data recovery (CDR). This 25G SFP28 DWDM module operates on a nominal wavelength of 100GHz ITU Grid, C Band DWDM wavelength. It can be Cisco, Juniper, Brocade, HW etc compatible. The DWDM transceiver allows 5G network operators to deliver higher bandwidth without deploying new fibers and save more by efficiently utilize existing fiber plants. The DWDM SFP28 transceiver is suitable for 5G wireless fronthaul network applications.
