Follow UsThe expansion of broadband networks is
currently causing an exponential increase in the number of installed
optical fibers. Network operators need new solutions to be able to
handle these quantities, to the building entry point in an orderly
and reliable manner. According to TRAI, the number of telephone
subscribers in India increased from 621.28 million in March 2010 to
671.69 million at the end of June 2010. This reflects YoY growth of
44.5 percent over the same quarter of last year. The overall
tele-density in India has reached 56.83 as on June 30, 2010. To
address this opportunity, Swiss cabling expert R&M has developed
its Single Circuit Management (SCM) portfolio. It is a modular tray
system for all areas of the network, from main distributor to
building entry point. The SCM core components allow you to manage
fibers and subscriber connections in a standard way. They support
current FTTH market strategies such as Point-to-Point (P2P) or
Point-to-Multipoint (P2MP) and open access, as well as the future
high-power and xWDM applications for ultra-broadband networks.
The SCM family is based on only a
handful of components, that can be put together without tools, using
a quick assembly technique. The scalable module support with
integrated fiber conduits serves as the backbone. One can click in
the trays to serve splice, breakout and splitter functions, as
needed. That way, a network operator can expand the FTTH
infrastructure flexibly and quickly or adapt it to meet its
individual needs.
One can thumb through the trays on the
module support and can assign each tray to a street, for example, or
a building, housing unit or subscriber. A large label field with
interchangeable labels, numbering and color coding makes the handling
of even large numbers of fibers easier. Individual subscribers can be
very easily connected and administered.
Ahluwalia, MD, R&M India
said, "India is still a growing FTTH market where the mass
market is yet to be tapped. To cater to such big number of untapped
users, a network backbone is necessary. Often, the Indian telecom
service providers come across challenges like large fiber counts,
identification complexities of fiber during maintenance due to large
volumes, messy cable work, and difficulties in maintaining or
handling classic design of a generic ODF. Our SCM portfolio will
address all these issues."
The large bending radius of 40
millimeters is one of the outstanding features of the SCM family.
Trays, modules and surfaces for placing excess lengths are designed,
so you need not bend the fibers any more than that. The bending
radius is maintained even in the smallest unit, the Venus Box FLA
house connection box, and also in fiber crossover. The stress-free
radius minimizes attenuation losses and optimizes handling during
installation. As a result, the SCM family from R&M lays the
groundwork for optimum performance in future high-power and xWDM
applications.
The SCM family is designed for
ultra-dense fiber optic infrastructures. The three different tray
types can be fitted with six or 24 fibers and shrink-fit or
crimp-splice holders or with 1:32 splittings. Combine SCM with the
Optical Distribution Frame (ODF) from R&M and you can manage up
to 1152 fibers in a single distribution frame. The R&M splice
enclosure for fine distribution underground in the last mile can
accommodate up to 96 trays or 1152 splices. The Venus Box FLA for the
building entry point can fit up to 144 fibers and splices when
combined with the SCM. The SCM is suitable for all types of cables
and fibers found on the market.
