R&M introduces self-assembly fibre optic connector According to R&M, it requires very few tools and no additional training to assemble the FO Field LC.

Cable specialist R&M today announced it has developed a new fibre-optic connector that is "the first field-terminable connector".

The FO Field LC is said to satisfy Grade C/1 requirements, the highest performance level for FO connectors. According to R&M it can be mounted within a minute at the construction site.

"For the first time, we offer an alternative to expensive fusion splicing," said R&M CEO Michel Riva.

"Now network operators and installation engineers can achieve top-quality home and office connections and repairs at the flick of a wrist."

The FO Field LC is suitable for single-mode fibres and also for multimode fibres in the categories OM2, OM3 and OM4. It can be used to assemble both full and compact fibres of 0.6 to 0.9 mm diameter and even bare 250µm fibres. A crimp-free strain relief was also developed specially for cables with a diameter up to 3.0 mm.

The FO Field LC can be assembled with the angled physical contact (APC) polish at the end-face of the fibre. The APC contact ensures the best possible light transmission in the connector. As a Grade C/1 connector, the FO Field LC has particularly favourable attenuation characteristics. Insertion loss (IL) is typically 0.25dB and return loss (RL) is over 60 dB plugged.

Installation engineers require no additional training to assemble the FO Field LC and very few tools. A pair of scissors, wire strippers and a standard cleaver are all that is needed.

"You simply cut the fibre at the required point and position it in the high-precision fibre guide," said R&M.

"Then you clamp the fibre with the press of a button and the wire by removing a wire clip and assemble the components.  A standard infrared source is used to check that fibre contacting is correct.  If the light goes out in the semi-transparent side window of the housing, the connection is fine. The FO Field LC can be reconnected. Field terminable versions of SC and other connector types will follow soon.

Jean-Pierre Labry, executive vice president, R&M Middle East, Turkey and Africa said, "R&M has once again demonstrated that it is at the forefront of technology innovation with the FO Field LC. Its ease of use, high quality, adaptability and cost saving potential make it a boon for network operators and comes at a perfect time when this region is seeing a great amount of fibre optic installations."
