Fiber backbone

Fiber backbone
280
The fiber backbone used in colocation data centers includes internal and external cabling (called outside plant) for connecting different areas. Outside plant consists of cables for connecting data centers to other network Point of Presence (POP) locations, the service provider’s central offices and other data centers, referred to as data center interconnections. An internal fiber backbone includes cables for connecting meet-me rooms with customer racks directly or through other distribution areas – such as the main, intermediate, horizontal or zonal areas – and creating connections between those areas.

A colocation fiber backbone has to meet several requirements. It must:
  • have sufficient fiber capacity to maintain the growth in the number of connections
  • offer high density in conjunction with bend-optimised fiber to be space efficient
  • be flexible enough to support various network applications, such as 40/100/200/400G over multimode or single-mode fiber
  • be scalable and allow more fiber to be added in the backbone when needed
  • be fast and convenient to deploy as well as easy to maintain
  • be secured and controlled by CCTV 24/7
  • be future-proof to support future applications

HUBER+SUHNER offers solutions for fiber backbones which meet all the above conditions and include fiber optic cables, fiber optic cable assemblies and trunk systems. Our customers have various different ways of creating a fiber backbone. Some prefer to use cable splicing, while others deploy pre-terminated trunk systems. The fiber splicing method remains the most cost-efficient option, but requires much more time for deployment. Although the pre-terminated method is the fastest to deploy, it is more complicated to plan due to the fixed length of the cable. 

Fiber backbone trunks may be Base-2, Base-8, Base-12 or Base-24, meaning that they use duplex connectivity (LC duplex) or connectivity with MTP® Base-8, -12 or -24 connectors. Fiber backbone trunks may be based on single-stranded cables or multi-stranded cables that provide higher density per occupied space. Some clients combine both approaches by using splicing on one side of a fiber backbone cable with pre-terminated connections on the other.

Data centers can benefit from automated cross-connects using optical switching technology. In this case, the fiber backbone must be connected to an optical switch and all changes in connectivity can be performed remotely or via SDN (Software-Defined Network) algorithms.
When the physical capacity of a fiber backbone has reached its limit, network system solutions from HUBER+SUHNER can help improve capacity by adding passive or active xWDM systems.
