Description
The WDM passive components, based on thin film filter technology, combine all network services/signals over a single fiber. Low insertion loss and high isolation between channels ensures reliable network performance.
YINGDA Photonics supply various wavelength Filter WDM with Stainless steel tube, ABS box, LGX cassette, 1U Rackmount ect.
Customized wavelength Filter WDM is available.

Features
Low insertion loss
High isolation
High stability and reliability
Application
Fiber laser
Fiber amplifier
Testing equipment
1×2 FBT splitter is with 1fiber input pigtail and 2 fibers outputs, and the device to connector both pigtails are not chip (for PLC Splitter) but welding machine to make them fused together, and outside the joint there is a stainless steel tube to protect it.
