These connectorized NoTail couplers and WDMs are free of fiber pigtails and ready to be inserted in optical systems without the headaches of tinkering with fragile and messy fiber pigtails. Another important feature of these devices is the short optical path delay (~30 cm) between the input and the output, desirable in many systems where the optical path balance is important, such as interferometric systems, ultra-short pulse systems, and fiber laser systems. Additionally, these devices have four strong magnets mounted on the back for temporary but secure placement on standard optical tables.

NoTail couplers split optical signals traveling in SM fiber at the specified split ratio.
