Optical Fiber Connector
An optical fiber connector terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing.
Every fiber connection has two values:
· Attenuation or insertion loss
· Reflection or return loss.
Measurements of these parameters are now defined in IEC standard 61753-1. The standard gives five grades for insertion loss from A (best) to D (worst), and M for multi-mode. The other parameter is return loss, with grades from 1 (best) to 5 (worst).
A variety of optical fiber connectors are available, but SC and LC connectors are the most common types of connectors on the market. Typical connectors are rated for 500–1,000 mating cycles. The main differences among types of connectors are dimensions and methods of mechanical coupling. Generally, organizations will standardize on one kind of connector, depending on what equipment they commonly use. Different connectors are required for multimode, and for single-mode fibers.
In many data center applications, small (e.g., LC) and multi-fiber (e.g, MTP) connectors are replacing larger, older styles (e.g, SC), allowing more fiber ports per unit of rack space.
Features of good connector design:
· Low insertion loss
· High return loss (low amounts of reflection at the interface)
· Ease of installation
· Low cost
· Reliability
· Low environmental sensitivity
· Ease of use
The mainly connector as below:
LC/SC/ ST/FC/E2000/MU/MTRJ
The market request is rather big for telecom and internet network.
Actually, the competition seem so intensly , if the production would not like control the Quality, it will not get good development.
