The GLOBALfiber G-COADM-2+1-LX4-xxyy is a passive CWDM OADM that adds and drops selected wavelengths on east and west optical paths. This LGX4 module version provides 2 add/drop channels + 1310 nm port for dual fiber, west and east networks, making it suitable for wavelength-based expansion of existing fiber infrastructure. Its channel configuration is Selected CWDM pair; 20 nm spacing.
The add/drop ports provide access to the selected wavelengths while the line ports carry the through path. Match the channel selection to the transceivers and include the loss of every add/drop and through section when planning the optical link.
