Fiber Optic Joints

In our magazine SPOTLIGHT 04/2012, the new generation of  fiber optic joints by SPINNER was presented. In the  meantime, the family has grown further and optimum solutions are available for virtually any application. This necessity results from the various customer applications and also from the internal use in hybrid joints (see also SPOTLIGHT 02/2013).

Dual Channel Single Mode Joint

In order to close the gap between the single channel joint and the multichannel joints, it was decided in 2012 to develop a very compact and robust 2-channel joint with an attractive sales price. This new member in the optic joints family impresses with its mechanical dimensions, as an outer diameter of 28 mm could be achieved with a total length of just less than 90 mm. This size is only possible due to the integrated and patented  mechanism. Thanks to its compact design, the joint has an overall weight of less than 230 g.

In addition, great importance was attached to high modularity; the customer-specific integration is ensured by means of a specific flange so that the joint can be integrated into virtually any system without the need to change the main components. The joint can, like all SPINNER optic joints, be realized in Single Mode (SM) designs in the frequency range of the infrared wavelengths of 1310 nm and 1550 nm and in Multi Mode (MM) designs for wavelengths of 850 nm and 1310 nm. Both fibers are bidirectionally, which means according to the specification the same optic parameters can be used. Each standard joint is equipped with two SM  fibers with a length of 1500 mm and FC connectors.

The rotary joints fulfil the specification (seemn table) with ave-m rage loss valuesu in the range ofm  3 dB at 0.5 db WOW. The design allows the same environmental conditions as for all other optic joints by SPINNER: temperature range between -40 °C and +85 °C, humidity up to 95 % rel. humidity, vibration and shock values as indicated in the specification. The joint meets the requirements of tightness class IP50.

In summary, it can be said that this optic joint, the smallest worldwide, with 2 Single Mode channels once again underlines the innovative capabilities of the SPINNER employees. Optic joints “made by SPINNER“ are a  guarantee for highest quality and performance with  minimum weight and required space.
