Products Description
OPTICO has a full range of high-performance optical circulators, such as normal circulators, Polarization Maintaining Circulator 3 Port, polarization-maintaining (PM) circulators, and polarization-insensitive (PI) circulators. These fulfill the strict standards for controlling and splitting optical signals in a wide range of situations.
PM circulators are made for systems that need to keep their polarization high. They send optical signals along a certain polarization axis (the fast or slow axis), which controls polarization and makes the device more stable. These devices are very important for 400G/800G high-speed optical communication systems, quantum communications, LiDAR, and fiber-optic sensing.

Features & Advantages
The Polarization Maintaining Circulator 3 Port uses Panda PM fiber to retain the polarization state of the optical transmission. This makes it great for applications that need to be sensitive to polarization.
Very low insertion loss: usually ≤0.8 dB (between ports), which means less loss of optical power.
A high extinction ratio: usually ≥20 dB, keeps the polarization state of the input light stable.
Great return loss performance: ≥50 dB, which keeps the signal strong.
Different frequencies for operation: The standard setup works with wavelengths of 1310 nm, 1480 nm, and 1550 nm. You can also customize it to work with wavelengths of 650 nm to 2000 nm.
It can work in a wide variety of temperatures, from -5°C to +70°C, thus it will work well in tough conditions.
Micro package size: Φ5.5 × L35 mm, which makes it easy to fit into small systems.
Standard connector: The basic FC/APC connector cuts down on backreflections, although you can also get bespoke connectors.
Can handle optical power levels of up to 300 mW, which is what high-speed systems need for high-power transmission.
Typical Application Scenarios
Polarization Maintaining Circulator 3 Port circulators are widely used in the following systems and equipment:
High-speed communication systems (400G/800G)
Used to control bidirectional transmission, supporting dual-fiber redundant paths and loop protection.
Fiber lasers
Achieve unidirectional transmission of output light, suppress backreflections, and improve laser stability.
Fiber optic gyroscopes (FOGs) and optical sensors
Used for nonreciprocal control of signal transmission paths, improving measurement accuracy and system anti-interference capabilities.
In quantum communication and polarization-maintaining links, they ensure polarization preservation during quantum state transmission and are suitable for various polarization encoding schemes.

FAQ
Q: What is the primary application of the Polarization Maintaining Circulator 3 Port?
A: It is widely used in polarization-sensitive systems such as fiber lasers, quantum communication, LiDAR, and high-speed optical networks, where stable signal direction and polarization preservation are critical.
Q: Can the wavelength be customized?
A: Yes. While standard versions support 1064 nm, 1310 nm, and 1550 nm, OPTICO provides customization across the 650 nm–2000 nm range to meet specific system requirements.
Q: What connectors and mechanical protection are offered?
A: Standard connectors are FC/APC to minimize back reflection, with other types available upon request. The device is housed in a rugged Φ5.5 mm steel tube with flexible Hytrel loose tubing for mechanical durability.
