WDM Devices

Wavelength Division Multiplexing (WDM) is a technology in fiber-optic transmission that uses multiple optical wavelengths to send data over the same optical fiber. GLSUN WDM Devices can help to improve the transmission capacity of optical fiber and the utilization efficiency of optical fiber resources.

GLSUN optical hybrid devices refer to the main functional devices in EDFA, such as optical isolators, WDM, gain flattening filters (GFF), couplers, and TAP PDs. GLSUN hybrid devices integrate two or more combined functions into one device, greatly reducing package size and cost. The hybrid fiber optic device is widely used in fiber optic amplifiers, CATV fiber optic links, fiber optic system testing and fiber optic LAN systems.
