200GHz DWDM OADM 2/4/8ch (Add/Drop)

The 200GHz DWDM OADM (Optical Add/Drop Multiplexer) is a precision passive component designed for dense wavelength division multiplexing (DWDM) optical communication networks. Operating within the ITU-T grid spaced at 200GHz (approximately 1.6 nm), this device enables the selective addition or dropping of 2, 4, or 8 individual wavelength channels from a multi-wavelength optical fiber stream, while allowing the remaining channels to pass through with minimal loss. Ideal for scalable and flexible optical network design, the 2/4/8-channel OADM simplifies network upgrades and maintenance by eliminating the need to demultiplex the entire signal. With low insertion loss, high channel isolation, and excellent thermal stability, it supports high-capacity data transmission in metro, regional, and long-haul fiber optic networks, making it a key enabler for efficient bandwidth management and network reconfigurability.
