Radio Frequency components used in the Wi-Fi hotspot on the Fan Mile in Berlin

September saw the start of the pilot phase of a public gigabit Wi-Fi access point on the famous Fan Mile in Berlin, Germany. HUBER+SUHNER is providing Wi-Fi antennas and coaxial cables, thus playing its part in enabling users in the area to surf, chat and stream for free for 30 minutes.

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 - fiber trays

LISA - fiber trays

LISA fiber trays are the side-facing connectivity blocks that are inserted into tray units within high density CDR and NGR racks. Designed for speed of installation and improved accessibility, the LISA fiber trays can be installed and removed in under 10 seconds. fiber trays are available to cover a wide range of applications including pigtail splicing and MTP-LC transitions.

 

LISA - patching tray units

LISA - patching tray units

LISA patching trays are generally used to build a cross-connect (system-to-line) configuration either within the same optical distribution rack (ODR) or between adjacent ODRs and servers with highest flexibility when using pre-terminated and factory tested cable systems. Cable systems can be patched easily thanks to a sliding and pivoting design.

Cable systems can be patched easily thanks to a sliding and pivoting design. Cables enter the patching tray from the rear left and right hand side of the tray unit and are then horizontally managed before entering the patching tray.

The LISA standard tray unit is a high-density chassis which manages pigtail splicing or MTP-LC transition fiber trays inside the centralised cross-connect rack. Incoming backbone cables enter the tray unit from the left hand side and jumper cables are connected on the right hand side of the tray unit.
Due to 19 inch fixings at the rear of the tray unit, full access can be enjoyed to all incoming and outgoing fibers and the integrated service loops allows the fiber tray to be inserted and retracted quickly and easily.
Standard tray units are supplied in 7U units with a density of 15 x fiber trays in total. Fully loaded 47U high CDR racks will accommodate a maximum of 6 x 7U tray units or 90 x fiber trays.

ODU - optimised distribution unit

ODU - optimised distribution unit

Within the LISA side access portfolio, HUBER+SUHNER offers a sub-rack which allows the integration of any LISA fiber tray into a standard 19" equipment cabinet. Flexible mounting options at the rear of the optimised distribution unit (ODU) make cable fixation quick and easy and bend-limiting conduits give ultimate protection to the incoming fibers. Patch cords are routed to the front side of the ODU and can either be guided to the rear of the cabinet (around the vertical rail) or vertically (along the front of the rail if sufficient side space is available within the cabinet). The ODU has a lockable steel door which provides security to the internal connections. This feature is particularly beneficial in collocation areas where multiple subscribers occupy the same rack space.
