MINIATURE F7 CONTACT FOR MULTI & HYBRID FIBRE OPTIC CONNECTORS - 2

MINIATURE FIBRE-OPTIC F7 CONTACT FOR MULTIFIBRE OR MIXED OPTICAL/ELECTRICAL OF THE 1K-5K AND 1B-5B SERIES In addition to the existing F2 fibre optic contact shown in our catalogue of Fibre-Optic connectors No 5, the B and K series can now also be fitted with the new miniature F7 contact. The main benefits of using this contact are: – Reduced size allowing increased contact density. As an example, a 4-channel fibre optic connector is now possible in series 3K/3B. – Use of industry standard 1.25 mm diameter ferrule and polishing processes. Contact design is based on the well-proven F2....

MINIATURE F7 CONTACT FOR MULTI & HYBRID FIBRE OPTIC CONNECTORS - 3

F7 Fibre Optic Contact Introduction The F7 type contact is designed to fit multi fibre connectors or mixed fibre optical/electrical connectors from 1B to 5B, 1K to 5K series. The design is based on the well proven F2 contact. Its main features are as follows: – Ceramic ferrules diameter 1.25 mm – Simple and fast polishing ensuring the physical contact of the fibre end face – After mounting on the cable, the contact is very easily installed in the main connector insulator, the particular shape of the contact body retains it in the insulator – Single type of cable assembly, regardless of...
