1310-2050nm 500mW Single Mode Optical Circulator (3-Port / 4-Port)
Standard Single-Mode Polarization-Insensitive Optical Circulator operating across 1310nm, 1550nm, and 2000nm bands. Built with low insertion loss (<=0.7 dB), high inter-port isolation (>40 dB peak), and low PDL (<=0.1 dB) for bidirectional fiber communications and fiber sensing.
Technical Specifications
Connectors add 0.3 dB insertion loss. Standard package: cylindrical steel tube or rectangular aluminum housing.
Configuration and ordering notes
Configuration parameters include center wavelength (1550nm for telecom/FBG, 1310nm for datacom, 2000nm for thulium laser) and port count (3-Port or 4-Port).
Key Applications
Fiber Bragg Grating (FBG) sensor demodulation; Optical Time Domain Reflectometry (OTDR); Bidirectional single-fiber transceivers; EDFA optical loops.
Package Drawing
Package dimensions depend on the configuration. The catalog, ordering information or drawing show different package references; engineering must confirm the final mechanical outline before ordering.
