The GLOBALfiber G-DMUX-O4C20-B-MLU is a passive DWDM Mux/Demux that combines and separates optical wavelength channels. This 19-inch 1U rack version provides 20 c-band + 2 o-band services / 44 wavelengths for single fiber, side b networks, making it suitable for wavelength-based expansion of existing fiber infrastructure. Its channel configuration is C21-C60 plus 1300.05, 1302.31, 1304.58 and 1306.85 nm. Use it with the corresponding complementary unit at the opposite end of the link.
Select the unit by its channel plan, fiber arrangement and connector type. The multiplexer routes optical wavelengths; the connected transceivers and available optical budget determine the usable service rate and transmission distance.
