LISA - centralised cross-connects

LISA (Leading Interconnect System Approach) 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 depth of 300 mm and full access from the front side, LISA racks 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 maximum density of 3600 LCD ports per rack (100 cassettes with 36 ports each) or 7200 LCD ports per floor tile when placed back to back.

LISA differs from conventional 19" panels in that it is fully accessible from the front. This means that users can install, patch or remove LISA fiber cassettes simply by sliding them out, without having to access the rear of the cabinet. Patching to the LISA rack is fast and easy and a dedicated slack storage area for patch cords allows users to make "any-to-any" patching with only two lengths of patch cords.

LISA chassis

LISA chassis

LISA chassis enable high-density applications and supports splice, patch, transition, splitter or WDM cassettes inside the centralised cross-connect rack. Incoming backbone cables are connected on the incoming side, while patch cords link ports on the opposite side of the LISA chassis.

The 19-inch fixings at the rear of the LISA chassis provide full access for all incoming and outgoing fibers and the integrated service loops allow the LISA cassettes to be inserted and retracted quickly and easily.

LISA cassettes

LISA cassettes

LISA cassettes are side-facing connectivity “blocks” that are inserted into LISA chassis within high-density 300 mm racks. Designed for speed of installation and improved accessibility, LISA cassettes can be installed and removed in under 10 seconds. LISA cassettes cover a wide range of applications including splicing, transition, splitting, WDM and patching.

The LISA solution is a flexible and modular fiber management system. By cleverly combining the available building blocks, this concept supports a range of different applications. The constant development of the LISA system enables customer needs to be addressed in the optimum manner.
