Isolators & Circulators
The OIWD Series 3-port fiber optical isolator integrates a 1480 nm WDM with a 1550 nm isolator in a compact format of 4.2 mm diameter and 32 mm length. It guides single mode 1550 nm light in the forward direction while minimizing back reflection and back scattering in the reverse direction for both polarized and unpolarized light. A third port directs single mode 1480 nm light into one of the isolator ports for pumping an erbium-doped fiber. Leveraging Our advanced all-glass thermal matching micro-optics design, the isolator offers ultra-high reliability, high stability over a wide operating range (-45°C to 85°C), low insertion loss, dual-stage high isolation, and a compact structure. Automated production also makes it cost-effective. These Telcordia-qualified components are ideal for applications in fiber amplifier systems, pump laser diodes, and optical fiber sensors.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
1550 Isolator / 1480nm WDM: Laser source protection depends on preserving the optical budget through the complete path. The 1550nm, 1585nm wavelength specification sets source and detector compatibility, while listed loss or isolation figure (Single Stage, Dual Stage) determines link margin and channel leakage. The fiber/interface entry (SM28, SM28e, PM1310) must match the connected components.
1550 Isolator / 1480nm WDM: Bidirectional signal routing depends on preserving the optical budget through the complete path. The 1550nm, 1585nm wavelength specification sets source and detector compatibility, while listed loss or isolation figure (Single Stage, Dual Stage) determines link margin and channel leakage. The fiber/interface entry (SM28, SM28e, PM1310) must match the connected components.

Technical FAQ
Fiber Type: SM28, SM28e, PM1310 · Fiber Cover: Bare Fiber, 900µm Tube. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Isolation: Single Stage, Dual Stage · Isolator Wavelength: 1550nm, 1585nm. Check the Isolators & Circulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
