Fibre Optic Connectors Production Program The production program is divided into 12 series of connectors. Their main characteristics and applications are shown below. Series 00 Latching Shell Miniature Feature Cable Construction Contact Type F4 Single-mode or Fibre Type ...
Page 9
... Introduction The Series These connectors series range from 2B to 5B, and have been designed to work with LEMO type fibre optic contacts. They are suitable for use with multi fibre or mixed fibre optical/electrical cables fitted with single- mode or multi-mode fibres up to 1500 micron in diameter. ...
Page 10
... In order to ensure the highest technical performance and to provide the optimum solution for a diversity of applications, LEMO has developed four types of fibre optic contacts; designated F1, F2, F3, and F4. These contacts are designed to operate with single fibre, multi fibre, and mixed fibre optical/electrical cable constructions and cater to single and multi- mode fibres from 9/125 to 1500 µ ...
Page 11
... These contacts are special with an oversized crimp bucket and can be used only with the series 3K.93C. A detailed range of conductor dimensions that can be crimped into LEMO contacts is given in the table above. See also the section on tooling (pages 97 to 106). Coaxial contacts The type C coaxial contact is removable and fixed in place by clips. Cable attachement is made by crimping. The square form is used to captivate center conductor and hexagonal crimping method for the cable shield ...
Page 12
... Connectors series and size should be selected according to the type of fibre, single-mode or multi-mode, cable structure and dimensions. See table (fibre optic connectors production pro- gram) and p. 8 (selection of the LEMO fibre optic contacts). Selection should also consider the environ- mental requirements such as indoor or outdoor applications etc… ...
