OPTOKON is a producer of WDMs and these can be manufactured in the full spectrum according to specific customer requests. We are now introducing the new three channel Wavelength Division Multiplexer, the 3-WDM. This MUX/DEMUX works on 1310/1490/1550 nm wavelengths with insertion loss less than 0.7 – 1.0 dB and isolation better than 40 dB between 1310/1550 and 1490/1550 channels. This high isolation, low loss WDM is achieved by combining innovative fused and thin film technology. The compact 3-WDM is designed to be used for FTTH projects in passive optical network infrastructures. Various types of pigtailing and connector terminations are available to meet your requirements.
