Isolators & Circulators

1550 Isolator / 1480nm WDM

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.
