Product Description

1310nm&1550nm 4 ports Polarization Maintaining Optical Circulator

Product Description

The 1310nm&1550nm 3-port Polarization Maintaining Optical Circulator(Both axis working) is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3.So fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port.They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed.

LW Photonics offers a large selection of polarization insensitive or polarization maintaining 3-port/4-port optical circulator. These devices can handle powers rang from 300mW to 20W, and have center operating wavelengths ranging from 850nm to 1650nm.

Note:
*Above specifications are for device without connector.
*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower.The default connector key is aligned to slow axis. Power transmit through the connector less than 2W.
*The transmission optical path of A type is different from B type:Type A: 1 -> 2, 2 -> 3, 3 -> 4; Type B: 1 -> 2, 2 -> 3, 3 -> 4;4->1
*For high power applications, we will use heat sink package, contact LW Photonics for details.
