Fiber OpticConnectors
Design of fiber optic connectors and fittings
SEDI-ATI stocks a selection of singlemode and multimode fiber-optic connectors to terminate any of the fiber-optic components and assemblies we propose.
Please note that connectors are an integral part of our products and that we do not sell them alone.
Custom connectors for your projects
Depending on the product and your application, we can advise you on your choice of connector. Or you can choose between our proprietary connectors specially designed for military, space, and aeronautics applications: FCXtreme®, NANOXtreme®.
For vacuum and high-vacuum applications, we can specify stainless-steel connectors in ST, FC, or SMA style.
Here is a non-exhaustive overview of our selection of standard optical connectors:
- E2000 APC,
- ELIO,
- FC/PC,
- FC/APC narrow key,
- FC/APC wide key,
- LC/PC,
- LUXCIS,
- MICROPTIQUE,
- MTP® male,
- MTP® female,
- SC/PC,
- SC/APC,
- SMA 905,
- ST/PC.
Fiber optic adapters, sockets and connectors
Depending on various parameters such as the optical fiber type, the connector type, and the application, the connectors can be mounted with a stainless steel or a ceramic ferrule (Zirconia).
Ceramic ferrules are preferred for applications sensitive to magnetic fields, while stainless steel ferrules are ideal for vacuum applications.
Adapters and bulkhead receptacles for fiber optic connectors
We also offer round and square bulkhead adapters, to connect two cables together. You can choose between E2000/APC, FC, LC, SC, ST, and SMA styles.
Besides, we have an SMA bulkhead receptacle to connect an SMA terminated cable on one side and to project light into free space.
And for power applications, we have developed the K-Power product line. These components are air-spaced SMA to SMA adapters aiming at transferring the optical power from an SMA-905 terminated fiber optic cable to another such cable. Discover the K-Power product line.
Do not hesistate to contact us to discuss your specific needs.
