1550nm Single Mode 3 Ports Optical Circulator
The 1550nm 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. Centered at 1550 nm with an operating range of ±30 nm, it provides low insertion loss of ≤0.8 dB, isolation of ≥40 dB, return loss of ≥50 dB, polarization-dependent loss of ≤0.15 dB, and crosstalk of ≥45 dB for reliable signal routing in C-band fiber systems.
Built with SMF-28e fiber, the circulator integrates easily into standard single-mode telecom systems and is available with maximum CW power options of 0.5 W, 1 W, or 5 W. It is well suited for bidirectional optical transmission, DWDM networks, FBG-based optical add/drop systems, optical amplifiers, fiber sensing, and test and measurement applications. Pigtail length, fiber protection, and connector type can be configured to meet specific system and installation requirements.
