DESCRIPTION WDM using the filter and grin lens technology. They are available for separating 1550nm from 1625nm wavelength or 1310+1550nm from 1625nm wavelength.
APPLICATIONS These singlemode WDMs are used for monitoring systems at 1625nm. They can be used on dual wavelength networks 1310/1550nm or in OTDRs for dual 1550/1625nm.
