The rise in the popularity of Colocation data centers over past years has been quite spectacular and is now one of the largest market segments in the IT world. Typically, a Colocation data center provides the premises, power, cooling, bandwidth and physical security while the customer installs its own switching, servers and storage. The white space is generally taken, according to customer needs, by rack units, racks, cages or private suites. In the past, Colocation data centers were almost exclusively used by companies for disaster recovery but the reality of low CAPEX and OPEX has attracted companies of all sizes who deem it more financially beneficial and easier to outsource their data center requirements. For most companies, outsourcing a non-core activity is also part of a risk-reduction strategy, and also alleviates the need to fund, operate, maintain and update an owned facility. This business model has its own particular challenges, with multiple tenants requiring specific and varied space configurations and security demands. Colocation data centers therefore face some unique infrastructure challenges.
Security is a Colocation pre-requisite where private access to server and storage racks is essential. To offer 24/7/365 operation to its customers who demand this level of service, Colocation infrastructure companies rely on high-performing and high quality products that will ensure their services operate efficiently and reliably, around the clock.
Downtime and poor service are unacceptable and Colocation companies pay the price for downtime. In such a competitive market, there is no future for service providers with infrastructures based on anything but the most advanced technologies.
HUBER+SUHNER offers a wide range of Optical Distribution Frames (ODF) and 19" equipment cabinets to meet all requirements. HUBER+SUHNER’s comprehensive range of equipment cabinets is designed to fulfil the diverse needs of the typical data center operator. The cabinet range is based around a common construction of anodised aluminium extrusions which match the innovative CDR passive optical rack system.
LISA - side access fiber management systems
LISA is a dedicated high-density fiber management system commonly used as a centralised cross connect in the main distribution area (MDA) of large data centers. With a 300 mm depth and full access from the front side; LISA cabinets can be positioned against unused walls, at the end of cold aisles or back-to-back on a single floor tile.
LISA racks have a density of 1500 LC ports per rack or 3000 LC ports per tile when placed back-to-back. For MTP applications the density is 1080 or 2160 MTP ports respectively.
The main difference between LISA and conventional 19" panels is the fact that LISA is fully accessible from the front side. This means that users can install, patch or remove fiber trays simply by sliding out the tray. This feature is much more attractive than 19" panels which generally require access to the rear side of the cabinet. Patching to the LISA rack is fast and easy and a dedicated slack storage area for jumpers allows users to make "any-to-any" patching with just two lengths of cord.
LISA - front access fiber management systems
The LISA front access system is focused on speed of installation and network security during installation or maintenance. The LISA front access system represents a modular group of products that enables seamless connection of passive optical networks especially in central office environments. Reliability and performance are key to the success of our industry which is why we have ensured that the highest level of fiber protection and bend-radius limitation are standard across all front access system solutions. The center piece of the front access system is a unique and versatile compact module that can be used for pigtail, direct cable splicing or for the integration of pre-connectorised passive components such as splitters.
LISA compact modules for MultiCircuit (MCM) applications combine simple installation and maximum security within an optical network. An integrated loose tube storage facility in each module allows easy removal of the splicing machine without disturbing neighbouring modules. In telecommunication environments, the compact module is particularly suitable for simple physical connections between the equipment and the passive infrastructure by means of inter-connect or cross-connect.
Polatis' highly reliable piezoelectric Directlight® beam-steering technology sets the industry standard for lowest optical loss and highest performance. With more than a billion port-hours accumulated on deployed units, the Polatis technology platform delivers a broad range of class-leading all-optical matrix switch products into demanding applications. At the core of Polatis optical switches is our patented DirectLight beam-steering technology that makes connections using compact piezoelectric actuators to align collimated beams of light from opposing arrays of input and output fibers with minimal loss, distortion or interference between paths. Alignment is maintained using feedback from integrated position sensors to ensure connection stability over time, temperature and external disturbances. Switching occurs completely independently of the power level, colour or direction of light on the path, enabling pre-provisioning of dark fiber and avoiding concatenation of switching delays across mesh or multi-stage switched optical networks. Polatis optical switches are fully non-blocking and available in sizes from 4x4 to 384x384.
