Optical Isolator
LEAD Fiber Optics Co., Ltd. a qualified OEM Manufacturer and Exporter / Agent for Optical Isolator especially for allproducts com ee fiberoptic manufacture of Fiber Adapter, Fiber Connector and Fiber Optic Coupler . It is professional on global B2B trading with Optical Isolator, Fiber Adapter, Fiber Connector, Fiber Optic Attenuator and Fiber Optic Coupler since .
Optical isolators are passive optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause backscattering and feedback problems. Optical feedback degrades signal-to-noise ratio and consequently bit-error rate. Ideally an isolator would pass all light in one direction and block all light in the reverse direction.
There are two major classifications of optical isolators: In-line isolators (fiber optic isolators) and free space isolators. Inline fiber optical isolators are designed in pigtail fashion. That is to say that they come with built-in fiber optic cable and connectors so that they may be integrated directly into a fiber optic system. Free space isolators, by contrast, do not have an integral connection system. They must be directly mounted to the object that needs isolation.
LFO Inline isolator series also come with your choice of single or dual stage packaging. Various types of pig tailing and connector terminations are available to meet your requirements.
They include 1550nm / 1310nm dual and single-stage in-line isolators, unique refection-type mini-isolators and 2-in-1 mini-isolators, and pigtailed free-space isolators.
