4 Channels 100GHz C21-C24, LC/UPC, West and East, Dual Fiber DWDM OADM, FMU Plug-in Module

1.Wide wavelength range for flexible network design.
2.High capacity for handling multiple channels of business. 3.Passive design with no external power source required.
4.Low loss for efficient signal transmission.

The 6COM-designed Dual Fiber 4CH C21-C24 DWDM OADM allows for drop and add of wavelengths ranging from C21 to C24 (1560.61nm~1558.17nm), with customization options available for other wavelengths. This OADM is in accordance with ITU-T G.694.1 100GHZ grid, maximizing the capacity of the C-band range.

The 4ch DWDM OADM port is a passive DWDM FMUC Plug-in Module that supports the drop and add of 4 channels of business using two fibers. The loss of waves in the west or east direction is less than 1.5dB, and the line loss between the west and east directions is less than 2.4dB.
