1528-1610nm C+L Band Single Mode 3 Ports Optical Circulator

The 1528–1610nm C+L Band Single Mode 3 Ports Optical Circulator is a passive, polarization-insensitive, nonreciprocal device designed to route light from Port 1 to Port 2 and from Port 2 to Port 3 while isolating the reverse optical paths. Operating across a broad wavelength range of 1528–1610 nm, it provides insertion loss of ≤0.9 dB, isolation of ≥40 dB, return loss of ≥50 dB, polarization-dependent loss of ≤0.15 dB, and crosstalk suppression of ≥45 dB for reliable broadband signal routing.

Spanning the C band and a substantial portion of the L band, its broadband response supports multiple DWDM channels over a wider spectral window and helps simplify C+L-band system design. Built with SMF-28e fiber, it is compatible with standard single-mode telecom systems and is available with maximum CW power ratings of 0.5 W, 1 W, or 2 W. It is well suited for C+L-band DWDM networks, bidirectional optical transmission, broadband optical amplifiers, FBG-based systems, fiber sensing, and test and measurement applications. Pigtail length, fiber protection, and connector type can be configured to meet specific system and installation requirements.
