    Wavelength-division multiplexers

    Singlemode fused WDMs are available for any two wavelengths between 780 and 1700 nm, with a minimum spread of 25 nm. Typical insertion loss is less than 0.3 dB, and isolation is 12 to 25 dB. The devices can be concatenated for higher isolation. Standard WDMs include 980/1550, 1480/1550, 1300/1550, 1550/1650, 1017/1300 and 1064/1550 nm. Custom WDMs are also available.
