Polarization Insensitive Optical Circulator It’s a compact, highperformance components, with high isolation, low insertion loss, low PDL, high stability and reliability. It is widely used in combination with fiber gratings and other reflective components in DWDM systems, wavelength add/drop, high speed systems, bi-direction communication systems, dispersion compensation, EDFA application and optical time domain reflectometer (OTDR) measurements.
The 3-Port 1060nm Circulator is a specialized optical component designed for high-performance applications requiring precise signal routing in the 1055-1065nm wavelength range. Featuring an epoxy-free optical path for enhanced reliability, it delivers typical insertion loss of 1.8 dB and high isolation up to 25 dB. With low polarization-dependent loss (≤0.2 dB) and high return loss (≥50 dB), this circulator is ideal for optical amplifiers, pump laser sources, fiber optic sensors, and test instrumentation. Compatible with Corning HI 1060 fiber and housed in a compact L34×W8.4×H8.4mm package, it offers flexible configuration options with bare fiber or 900µm loose tube, multiple connector types, and various fiber lengths.
The 3-Port 850nm/980nm Circulator is a cost-effective and reliable optical component designed for applications requiring low insertion loss and stable signal routing. Operating at wavelengths of 850±20 nm and 980±20 nm, it features typical insertion loss of 1.3 dB and high isolation of up to 25 dB. With low polarization-dependent loss (≤0.2 dB) and high return loss (≥50 dB), this circulator ensures efficient performance in optical amplifiers, pump laser sources, fiber optic sensors, and test instrumentation. Available in compact package sizes (Φ5.5×L38 or L50) with bare fiber or 900µm loose tube options, multiple connector types, and various fiber lengths for flexible integration.
Four-port Polarization Insensitive Optical Circulator is a special type of circulator that has one input (port 1), one output (port 4) and two common ports (port 2&3). The light goes through port 1 to port 2. At port 2, any incoming light is guided to port 3 as output, while all input from port 3 is guided to port 4 as output.Compared to three-port circulator, four-port device has one additional bi-directional port. Hence, it can be used to construct more flexible or more complex optical fiber sub-systems, such as add/drop module, mux/demux module, multi-port bi-directional splitters, WDM optical router, etc.
The Maintaining Bias 3-Port Circulator is a high-performance polarization-maintaining optical component designed for applications requiring low insertion loss, high isolation, and minimal polarization-dependent loss. It features an epoxy-free optical path for enhanced long-term stability and reliable signal directionality from Port 1 to Port 2 to Port 3. Operating at key wavelengths such as 1310 nm, 1550 nm, and 1480 nm, this circulator offers high isolation (≥50 dB typical) and low insertion loss (0.7 dB typical). It is widely used in optical amplifiers, metro area networks, wavelength add/drop modules, dispersion compensation, and bi-directional communication systems. Available with PM fibers, multiple connector options, and various fiber lengths to support flexible system integration.
