The optical couplers are fused fiber branching devices that split the portion of light allowing optical monitoring. The devices are used extensively in amplifier power control and in transmission equipment for monitoring the performance. The polarization dependent loss coupler is offering low levels of sensitivity to polarization and enables effective management of optical networks. The couplers are available in a wide range of split ratios, lengths and packaging. The Polarization maintaining fused coupler can be bought online for its best usage.
A fused coupler is consisting of two, parallel fibers that can be stretched, twisted, and fused together. The length of the coupling region determines the coupling from one fiber to the other. The Polarization maintaining fused coupler is used to add additional functionality to the network such as network status monitoring. It is the most cost-effective way to minimize the loss and maximize the wavelength isolation. Polarization maintaining fiber coupler is capable of combining two or more inputs into a single output and also divides a single input into two or more outputs.
fiber-mart.com is the most unique fusing technique that builds the 980/1030/1064nm polarization maintaining fused coupler (PMC). The ratio can be selected according to the requirement and the businesses can benefit a lot buying the fused coupler online.  It features low excess loss, small size and high polarization extinction ratio. The polarization maintaining fused coupler is widely used for optical sensors and amplifiers. A unique fusing technique is used for building the polarization maintaining fused coupler.
How does a fused fiber coupler work?
A fused coupler is consisting of two, parallel optical fibers which are close to each other due to twisting, fusing, and stretching. The length of coupling region determines the coupling ratio from one fiber to the other. Light is launched into the coupling ratio during the manufacturing process and the output power from each output port is carefully monitored. After the achievement of the desired coupling ratio, the fully automated process stops. The process is known as Fused Biconical Taper (FBT) process.
