DK Photonics 1310/1550 nm Filter WDM(Standard and High isolation) is based on thin-film filter technology and metal bonding micro-optic packaging. This component is used to combine or separate 1310 and 1550nm band signal. The High isolation WDM device offers a very flat and wide passband, low insertion loss, and much higher isolation than the Standard isolation WDM device. This product is ideal for high-power Optical Amplification System and WDM Network applications.

The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
