Coupled
with emerging high-speed network standards and rapidly advancing
technology, growing demand for faster access to larger volumes of data
is having a profound impact on network infrastructure. As 40G becomes a
standard option in data centers, the challenge of connecting 40G
equipment with existing 10G equipment moves front and center. Two
different types of solutions have been developed to connect 10G
equipment with higher-speed equipment in the same data center: breakout
cabling and modular patch panels. It is essential to understand the
benefits and challenges of each type of solution in order to select the
one that meets your current and future connectivity needs most
effectively.
Breakout Cabling Solution
A breakout cable
is a multi-strand cable, which is divided into multiple duplex cables.
For instance, a 40G breakout cable has four individual 10G duplex cables
totaling eight strands, while a 100G breakout cable has 10 duplex
cables and 20 strands. A breakout cable has LC connectors at one end and
an MTP/MPO connector at the other.
Working Principle, Benefits and Challenges
Let’s
take an example to get clear the working principle of breakout cables.
Assume you want to integrate 10G servers into a 40G network. For each
port on the switch, you will need a breakout cable with an MTP/MPO
connector on one end and four duplex LC connectors on the other end. The
MTP/MPO connector plugs into the 40G switch port and each duplex LC
connector plugs into a 10G port on each server.
The
primary benefit of using the breakout cabling solution is that
slower-speed equipment can be connected to higher-speed equipment
successfully, such as the 10G servers and 40G switch. Although the
breakout cables enable different speed equipment connection, they
present some challenges, such as cable congestion, repair, flexibility
and scalability. Breakout cables are difficult to reconfigure when you
add or upgrade equipment, requiring frequent overhauls of cabling
infrastructure. Not only is this approach costly and time-consuming, it
limits your ability to plan properly for future growth. This is
specially problematic given that future port and bandwidth growth will
inevitably require integrating new network cabling standards.
Modular Patch Panel Solution
Modular
patch panels are comprised of rack-mountable enclosures designed to
house a range of modular, removable fiber cassettes. Supporting various
fiber network cabling standards, the cassettes are easy to mix, match,
add and replace as your connectivity needs grow and change.
Working Principle, Benefits and Challenges
The modular fiber cassettes
are the key to this solution. The cassettes allow users to interconnect
different fiber speeds simply by plugging standard, duplex LC cables
into one side of the cassette, and MTP/MPO cables into the other side.
Modular
patch panel solutions offer a range of benefits, including integrate
diverse cabling standards, provide flexibility and scalability, reduce
cable congestion and save space. Modular patch panel solutions allow the
users to connect diverse network cabling standards seamlessly, such as
10/40/100/120G. When you need to integrate new cabling standards to
support higher network speeds, you can simply swap existing cassettes
with new cassettes that support the new standards. The network can grow
and change on-demand, without the costly, labor-intensive hassle of
replacing channels end-to-end. Moreover, reduced cable slack means less
clutter, less confusion and an easily organized, better-labeled cabling
infrastructure. By managing varying port densities and speeds in a
single high-density patch panel, the users can save valuable rack space,
helping to lower data center costs.
Although
the modular patch panels have many advantages, they also have
challenges. The biggest challenge is selecting a modular patch panel
solution with the features and capacity to meet your current needs, as
well as flexibility and scalability to adapt to and grow with your
future needs.
Modular Patch Panel – A Solution for Future-Proofing Network
With
increasingly higher network speeds always just around the corner, you
want to make sure your investment in upgrading and building out your
network infrastructure is spent wisely. Breakout cabling solutions
served an important purpose when 40G switches first entered the
marketplace and required immediate connectivity solutions. However, they
require end-to-end replacement every time you upgrade equipment.
Modular patch panel solution has been a game-changer. Designed for
maximum connection density, flexibility, scalability and compatibility
with both existing and emerging high-speed network standards, they allow
users to seamlessly and conveniently integrate equipment with different
network speeds to meet connectivity needs today, and cost-effectively
future-proof network for tomorrow.
