1460-1625nm S+C+L Band Single Mode 3 Ports Optical Circulator

1460-1625nm S+C+L Band Single Mode 3 Ports Optical Circulator

The 1460–1625nm S+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. Across its ultra-broad 1460–1625 nm operating range, 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 stable broadband signal routing.

Covering the S, C, and L telecom bands within a single component, the circulator supports optical signals and DWDM channels across a 165 nm spectral window, reducing the need for separate band-specific circulators in broadband systems. Built with SMF-28e fiber, it is compatible with standard single-mode telecom infrastructure and is available with maximum CW power ratings of 0.5 W, 1 W, or 2 W. It is well suited for ultra-wideband 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.
