Fiber to the Home (FTTH) is spreading at breakneck speed. Telecommunications companies have a lot to do in the final mile to customers. They have to connect and manage large quantities of optical fibers in the distributors of the access networks. This can be complicated and the distributor room is often cramped. This is why R&M wants to further simplify and increase the density of FTTH cabling. To this end, R&M is now expanding the PRIME family with two modules for single fiber management on network level 3.

These modules are compact fiber inserts for the various PRIME sub-racks and distribution frames, each with twelve FMTS compact splice trays with optionally 4x shrink (HS) or crimp (ANT) splice contactors. The inserts support the two- and four-fiber concept for FTTH networks. At least two fibers are required to connect a subscriber or a house to the broadband network. The four-fiber concept opens up the access network to more offers and more competition among Internet service providers.

The new distribution modules from R&M are called the PRIME Single Termination Unit (STU) and the PRIME Single Splice Unit (SSU). They are used to provide as many fibers as possible for subscribers in a PRIME rack and to administer them securely. The STU fiber unit accommodates plug connectors for up to 48 fiber terminations. R&M uses the connector types LC-D, SC and E-2000™.

The SSU fiber unit is used to connect 48 fibers per splice. The sub-racks occupy a 3/4 height unit and can be retrofitted into existing 1U or 3U sub-racks.

Together with the inserts, R&M developed compact FMTS splice trays for fiber management. The splice trays, which can be mounted tool-free, work like index cards.

Incoming and outgoing fibers are crossover-free in the guides. This allows technicians to assign and easily document the subscribers without any confusion. They can also carry out inspections and maintenance work quickly. A snap-in mechanism fixes the PRIME fiber units for splice, patch and maintenance work.
