Hyperscale
at the Transition Splice Point
The family of Building Entrance Facility (BEF) products for
large data centers is growing. R&M USA is launching three
new models on the market. The scalable splice cabinets
will set new standards for fiber optic management at the
Transition Splice Point.

Whether data centers are capable of growth
or not is already decided at the gate. The
cabling capacities at the building entry point
must be as scalable as networks and racks in
the white space.
The growing number of arm-thick high count
fiber cables is an issue for hyperscale and
colocation data centers. Their fiber bundles
should be distributed as efficiently as possible
over the smallest possible area. This is a

complex matter as it regularly involves tens
of thousands of fibers. And the numbers are
increasing all the time.
R&M wants to simplify things which is why
the BEF cabinets were developed. After
the successful launch of the BEF 60, three
cabinets for 24, 72 and 144 splice drawers
are now being added. Up to 384 fibers can
be spliced in each splice drawer. In the case
of ribbon fiber cabling, up to 55,296 splices
fit into the double cabin BEF 144.
Smart innovations
Modular lightweight construction, quick
mounting technology, stable cable guides
and splice drawers with intuitive operation
facilitate work. The cabinets are made of aluminum
plate and can be stacked. This means
data centers can make use of the room height
and minimize the amount of floor space required.
Doors, walls and the drawer supports
can be removed for assembly. Spacers allow
the cables to be inserted at the rear.
The cable entry guides are one of the clever
innovations in the BEF cabinets. Fast and
sturdy shingles hold the rigid cables firmly
in place. They support the subsequent introduction
of additional cables. The angles can
be positioned and divided in different ways in
order to insert the cables in the appropriate
places. Time-consuming threading through
holes is no longer necessary. The cables
can be prepared for mounting outside the
cabinet.
Stackable high count fanout kits with a flat
breakout box can be assembled anywhere on
the rear wall. They pick up the cable ends and
stabilize the fiber bundles on their way to the
splice drawers.
