Enspace High Density Fibre Solutions For Data Centres

Get ready for 10G, 40G, 100G … and beyond

As high density data centres migrate to 40 and 100 gigabit speeds, selecting the right cabling solution is becoming increasingly important and more difficult than ever before. Accommodating fast-changing technology and capacity involves detailed choices and requires specialist knowledge.

The ideal cabling solution should be ready for the future, support several generations of active equipment and present no obstacles during operation. It should be quick and easy to install. Easy access and management of connections is required to make fast and effective changes.

Nexans flexible, high-quality LANmark ENSPACE products facilitate the design of a wide variety of configurations, comprising high numbers of connections within the same channel, with reach beyond that of standards-defined distances.

A combination of quality products and technical know-how allows Nexans to support you during the design, installation and operational phases.

1. ENSPACE for every zone of your data centre

Data centres have many network layers and zones. The core network from Spine to Leaf switches and the access network towards servers have different speed and density requirements. Moreover every data centre has its own set of challenges. ENSPACE offers flexible solutions for different installation needs.

ENSPACE supports core and access networks

Core networks are moving quickly from 40G to 100G. Very large data centres start even to look into options for 400G. For 40G and 100G IEEE approved solutions for multimode are based on parallel optics. Recently proprietary solutions based on duplex LC are rapidly gaining popularity. ENSPACE can support both approaches.

For the network between the servers and the switches, IEEE has already approved standards for 10G, 25G and even 50G. All these solutions are based on duplex LC. ENSPACE solution with LC or MTP/LC modules support the access network for the next 3 generations! No migration in cable infrastructure is expected for the foreseeable future.

Different zones, different density requirements

Density requirements vary from zone to zone in a data centre. In patching zones to the Spine switches many hundreds of connections need to be managed. ENSPACE UHD panels reduce the number of racks required saving expensive space in data centres.

Other zones like server racks have less connections. And stacking of the panels is not required. ENSPACE HD panels, with 48 ports per height unit, offer a cost effective solution.

2. The right Density Everywhere

The right density and scalability without compromising operations. In a modern data centre there is limited space for passive cabling. Furthermore, you must be able to migrate to higher speeds or add ports without disrupting operation. To accommodate these requirements, density, accessibility and scalability are key.

ENSPACE HD

The ENSPACE HD panel accommodates 8 ENSPACE modules on 2 fixed trays for a density of 96 LC in 1U. The panel is typically used in server racks or patching zones of medium sized data centres. The modules can be installed from the front or the rear for a maximum of flexibility during installation. With the integrated guides on every tray the patch cords are neatly managed to the side. Uniboot patch cords with bend-insensitive fibre allow for sharp turns and bends within cable routes in the rack. The round patch cable’s 2mm diameter is optimised for high density areas.

ENSPACE UHD

LANmark ENSPACE UHD solution increases the number of connections in 1U by 50%. ENSPACE UHD panels feature three individual sliding trays per “U”, which can be pulled forward for fingertip access when installing or disconnecting patch cords. This approach allows 144 LC connections in a 1U panel and up to 576 LC connections in 4U without compromising the operational efficiency of patching. A sliding and tilting rear tray facilitates installation from the rear and allows for scalability without interrupting already installed ports.

3. Optimising Design

Complex configurations made easy

One of the trickiest parts of designing a data centre is capturing all the cabling requirements, taking into account the widely varying requirements, benefits, specifications and technological limitations of different cable types, network devices and systems. Will a certain cable type work correctly at the specified length? Where can I best place storage capacity? How many connections can I add per channel in a given design?

Nexans can provide detailed, documented advice, based on decades of practical experience, far-reaching knowledge and state-of-the-art hardware. With our advanced solutions for ultra high density patching and rack cabling, we can support the creation of optimal designs for every data centre build or expansion.

Building in flexibility

Today’s data centre infrastructure requires built-in flexibility. Different racks and rooms have to be connected with high-speed protocols. The higher the speed, however, the lower the available optical power budget.

Nexans high-performance LANmark-OF connectivity with minimised insertion loss allows greater lengths and more connections without sacrificing quality or reliability. What’s more, Nexans expertise and deep involvement in the development of new protocols and cabling standards means we can help you find the right solution every time. Our low-loss connectivity solutions exceed all of the requirements of the relevant standards to ensure your data centre performs better and more reliably.

4. Different environments, different cabling

Choosing the right pre-terminated cabling types

When making cabling and infrastructure decisions, there are many aspects to consider; different ‘environments’ – Spine to Leaf switch, Leaf switch to server, SAN, representation of switches… – all require different types of cabling. What type of connectivity should you be using? Multimode or Singlemode with LC connectors? Or MTP* for protocols based on parallel optics?

Nexans can advise you in the choice of assemblies using LC or MTP connectivity optimised for fast installation, with no technology or connector bias, choosing the best solution for each individual section of the network.

LC connectivity moving from 10G to 25G/40Gand even 100G

LC connectivity has a proven track record for 10G in data centres. New standards developed for 25G and proprietary solutions for 40G and even 100G based on duplex transmission are extending the functional lifetime of LC connectivity in data centres. What’s more, LANmark ENSPACE LC Pre-Term solution facilitates quick and easy installation with its innovative dual stage fan-out.

MTP for 100G/400G and for rapid deployment of LC connectivity

High-speed protocols require parallel optics supported by advanced multi-fibre MTP connectors. Pinned connectors on the MTP-MTP Pre-Terms require only one type of patch cord, reducing operational complexity for 100G and even 400G. With pre-installed MTP-LC modules LC connectivity based networks are deployed easy and very fast.

5. Short deliveries and fast installation

Deployment speed is essential to successfully build and expand data centres. This requires fast deliveries and rapid, hassle-free installation – Nexans can help in both these areas.

Short delivery times

Nexans can guarantee short delivery times and respond rapidly to changing demands with its own factories throughout Europe and around the world, in-house specialist design knowledge and logistics experience.

Tailor delivery schemes

We create tailor-made delivery schemes and palletising, perfectly aligned to construction planning. The right deliveries take place at the right time, for fast and perfectly coordinated installation. Clear labelling on individual Pre-Terms, boxes and pallets allows for immediate identification.

Fast and easy installation

LANmark ENSPACE MTP-MTP Pre-Terms can reduce time required on-site by as much as 70 % compared to traditional termination methods.

LC Pre-Terms with dual staged, neatly packaged fan-outs avoid tangled connectors and allow hassle-free, cassette-by-cassette installation. Coloured boots facilitate errorfree implementation of the required fibre pair-flip during installation and make fibre identification faster and easier. MTP-LC modules reduce installation time even further.

Cables are delivered at individually specified lengths – there’s no excess cable to be organised in racks and space is used optimally.

Installation flexibility

In some situations, there is an installer preference for either the MTP trunks or the LC trunks, or even field termination. With ENSPACE products, the end-user maintains an identical product use and performance, allowing the installer to utilize their cost effective method.
