DATASHEET
The G&H fused PM WDM, combines
multiple wavelengths of light in PM fiber
whilst maintaining polarization.
G&H proprietary PM manufacturing technology
provides low loss, with high polarization extinction
ratio. The all fiber construction offers excellent
reliability and high power handling characteristics.
These high performance parts are available in many
wavelength configurations, housing, fiber and
connector options and can therefore be readily
specified in a wide variety of applications, enabling
rapid design cycles and new project builds.
In common with all PM components, it is necessary
to launch into either the slow or the fast axis to
maintain polarization. For the G&H PM WDM,
specifications are based on slow axis launch,
although fast axis versions are also available if
requested.
● Low loss
● High PER
● High power handling
● PM fiber on all ports
● Slow axis operation as standard
● Fast axis operation available on request
● Telecoms
● Instrumentation
● IR Imaging
● Biomedical
● Industrial
● Defense
● IR counter measures

Operating/storage temperature range -5 – +75°C/-40 – +85°C
Fiber type4 PM PANDA fiber
1 Measured reference port P3 input for signal wavelength, P2 input for pump wavelength and P1 input for signal and pump wavelengths.
2 For operation at powers of greater than 4 W the component housing and fiber must be adequately heat-sunk (for additional
information contact G&H sales). Components intended for high power operation are only available in the 2x2 configuration.
Component performance and reliability under high power must be determined within the customer system.
3 The performance and reliability of optical connectors is not guaranteed for optical powers of greater than 1 W.
4 Various fibertypes available, please contact G&H sales for additional information.
