Product Description:

Fused couplers are used to split optical signals between two (or more) fibers or to combine optical signals from two (or more) fibers into one fiber. They are constructed by fusing and tapering the fibers together. This method creates a simple, rugged, compact method of splitting or combining optical signals. Typical excess losses are as low as 0.2 dB, while split ratio tolerances range from ±5% to ±0.5% at design wavelengths depending upon the splitting ratio. These devices are bidirectional and offer low backreflection and insertion losses.

OZ Optics’ fused PM Splitters exhibit a broad operating wavelength range of up to ±20 nm for 1550 nm region devices. For operation within the standard bandwidth of a splitter, it is best to order a standard center wavelength for lowest price and quickest delivery. Fused PM splitters are also available on smaller core fibers for 1064 nm, 980 nm and other wavelengths. (Nonstandard center wavelengths may require minimum order quantities or set up charges. Please contact OZ Optics for assistance).
