In intensive research and development efforts, R&M has developed the first high-end alternative to fiber splicing. This alternative involves field-terminable LC and SC connectors called FO Field. Every installer can attach them to the optic fibers at the construction site in less than a minute.
The FO Field LC and the FO Field SC meet the requirements of the top performance levels Grade Cf/1 and Grade Cf/2, respectively. The FO Field SC is currently being introduced to the market and typically has an insertion loss (IL) of 0.2 dB. The FO Field LC has been available somewhat longer and has a typical insertion loss of less than 0.5 dB. Both connectors have return loss (RL) in excess of 60 dB. In earlier times, it was nearly impossible to extract this kind of performance from field-terminable fiber optic connectors. R&M has now accomplished this feat thanks to the APC contact surface (APC = Angled Physical Contact) and a low-tolerance fiber guide. After wiring, installers can use an infrared source to determine within seconds whether the connection works.
Both versions of connectors can be combined with all the typical types of cables, with single mode and multimode fibers sized 125 and 250 μm. For multimode fibers, the categories OM2, OM3 and OM4 are specified. It is possible to wire both full and compact fibers with sheathing up to 600 to 900 μm or cladding from 1.4 to 3 mm in diameter.
Along with the new advances FO Field LC and FO Field SC, the R&M product range also includes field-terminable connectors for PCF cables. They are especially well suited for the installation of fiber optic networks in industrial plants and cover the medium performance range. There are field-terminable connection products for polymer optic fibers (POF), too.
