Isolators & Circulators
Bypassable/Switch Optical Circulator 1310nm & 1550nm
The CL Series bypassable Optical circulator works in either circulator mode or bypass mode. In the circulator mode, it works as a regular 3 port circulator, light entering port 1 passes out through port 2, and light entering port 2 passes out through port 3. In the bypass mode, light entering port 1 will output through port 3 bypassing port 2. Switching between these two working modes is activated via an electrical control signal. This is achieved using our patent pending non-mechanical configurations, which also feature Latching operation that preserves the selected working mode after the drive signal is removed. Our all solid sate bypassable circulator features low insertion loss, high channel isolation, fast switching speed, and extremely high reliability and repeatability.

System integration
Integration and compatibility
Use these checks to connect Bypassable/Switch Optical Circulator 1310nm & 1550nm to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SMF-28, PM1550, PM1310 · Fiber Cover: 900 um tube
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1550, 1310
- Check the Isolators & Circulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
