Real world fiber optic splitters show uniform performance across the whole spectrum of interest from 1260 to 1600 nm.
Fiber optic coupler 50 50.
F cpl b12355 optical fiber coupler broadband 1 x 2 50 50 1310 1550nm.
These couplers are available with a 40 nm bandwidth and a coupling ratio of 50 50 75 25.
Wideband couplers that can be used at 470 nm are featured below.
1x2 broadband coupler.
Newport s wide range of fiber optic couplers have been developed using fused fiber technology.
Thorlabs single mode 1x2 fiber optic couplers also known as taps have a flat spectral response across the entire specified range.
It features good uniformity low excess loss and very low polarization sensitivity.
Advantages are the low loss easy coupling with the optical fiber transmission line and no polarization dependent loss.
Thorlabs couplers are available from stock in one of five ratios.
2x2 fused fiber optic couplers can split or mix light between two optical fibers with minimal loss and at a specified coupling ratio.
Star couplers with up to 32 ports have been possible using fused tapered fiber 3 db couplers.
50 50 fiber optic coupler splitter 1310nm single mode the fc series fiber optic coupler is based on agiltron s fused biconical taper technology and compact packaging structure.
The optical fiber couplers allow bi directional coupling and can be used to either split or combine signals.
