25G xWDM Optical Transceivers
Compared with ordinary optical transceivers, the biggest
difference is xWDM optical transceiver can save fiber resources and costs. At
present, the commonly used 25G WDM optical transceivers are divided into 25G
CWDM, 25G DWDM and 25G LWDM optical transceivers.
25G CWDM optical transceiver uses CWDM DML lasers and
PIN/APD receivers. The working wavelength ranges from 1271-1371nm, 1471-1571nm,
with each interval of 20nm, and the maximum transmission rate is up to
25.78Gbps. The transmission distance can reach 10km-40km through single-mode
optical fiber connection, which can be applied to short-distance data transmission
in 25G Ethernet switches, routers, network interface cards and storage network
equipment.
25G DWDM is hot-swappable optical transceiver which uses
DWDM technology, the working wavelength is 1528.77nm-1563.86nm, with interval
of 0.8nm, a total of forty-four channels can be selected, and the maximum
transmission distance through single-mode fiber is up to 10km, widely used in
25G Ethernet and 5G fronthaul CPRI/eCPRI networks.
