SKU: ILPM

Photonwares’s ILPM Series Fiber Optic Tap Power Monitors are used for in line power measurement and precision power controlling. It is based on a patent pending design that taps light without bending and grooving fiber, or using lens and optical coating. This novel power monitor provides industrial exceptional performance in ultra-low loss, low polarization and wavelength dependence, high directivity, variable tap ratios, as well as low cost and high reliability.  The continuous fiber device is particularly suited for adapting to various types of fiber and for high power handling. This power monitor has a miniature ceramic package houses offering a stable optical tap and PIN photodiode as well as GR1209 and GR1201 compliance qualification.
