1×2 CWDM Single Channel 20nm Spacing in steel tube with LC/FC/ST/SC

The 1×2 CWDM Single Channel is an optical device used in WDM (Wavelength Division Multiplexing) fiber optic communication systems, specifically as a splitter or combiner for a single channel in Coarse Wavelength Division Multiplexing (CWDM). The “1×2” configuration means it has one input port and two output ports, or vice versa, allowing a single optical signal to be split into two or two signals to be combined into one. CWDM technology enables the transmission of multiple signals on a single fiber, each using a different wavelength, with typical spacing of 20 nm. The “Single Channel” designation indicates that this device is designed to handle a specific CWDM wavelength, such as 1270 nm or 1290 nm. This makes the 1×2 CWDM Single Channel device essential for efficient optical signal management in fiber networks, particularly in applications that require effective fiber resource utilization.
