TW1550R5A2 In Stock

The TW1550R5A2 by ThorLabs is a top-of-the-line wideband fiber optic coupler designed for professional applications. With its impressive operational range of 1450 to 1650 nm and minimal excess loss of <0.15 dB, the TW1550R5A2 is a reliable choice for demanding optical setups. Featuring a 50:50 coupling ratio and bidirectional functionality, the TW1550R5A2 allows for seamless integration into various optical systems, with any port serving as an input. The 0.8 m fiber leads are jacketed in Ø900 µm Hytrel® tubing, ensuring durability and compatibility with FC/APC connectors for smooth connections.

With a maximum power handling capacity of 1 W with connectors or bare fiber, and 5 W when spliced, the TW1550R5A2 is capable of handling high power applications with ease. It is important to note that for standard couplers, the coupling ratios listed correspond to the ratio of the output power from the white port (signal output) to the red port (tap output) when the white port is used as the input. To maintain optimal performance, it is crucial to keep the fiber end face clean and free from debris or contamination, especially when operating the TW1550R5A2 at high power levels. Proper cleaning with appropriate cleaning solutions for fiber bulkhead and connectors is recommended to prevent any potential damage.
