are designed for harsh environments is to drop disconnected connectors in dirt, then rinse them off with water or wipe with a cloth and then mate them. A good connector system should not be affected and should work straight away, every time. A good example of expanded beam
technology would be the Cinch Fibreco Junior range of connectors. Derived from the military-proven MIL-DTL-83526 connector style, they feature sealed single- mode and multi-mode expanded beam inserts within a fully sealed hermaphroditic circular metal shell. Te circular metal shell can be specified in aluminium, marine bronze and stainless steel, with a range of different plating finishes. All Cinch expanded beam connectors are designed to perform well under harsh conditions and in addition to the robust materials and secure construction, every Fibreco expanded beam connector insert utilises a unique, patented optical arrangement, whereby the critical interface between the optical fibre
and the lens is permanently sealed in a controlled atmosphere during manufacture. Tis ensures that no dust, moisture or other contaminant can migrate into the optical path within the connector insert during the product’s life. Major benefits of expanded beam
connectors include: • Use of lenses to widen the optical signal, reducing sensitivity to dust and misalignment.
• Different polishing techniques to improve performance based on application needs.
• Combined electrical and optical connections in one multi-channel rugged assembly.
• Ease of installation and maintenance. • Possibility of field termination and repair. • Quick connect push-pull or bayonet coupling design for rapid deployment.
