GPON installation in high rise buildings via Fiber Tree system

In this document we would like to demonstrate a GPON application and installation example on a high rise building by using Canovate fiber tree system. Polat Tower is a commercial &residential complex of 40 floors, and on each floor we have 8 customers. Thus there is appx 320 FTTH subscribers in this building. Fibertree solution has been chosen as preferred solution due to its advantages in terms of reduced installation time, ease of installation and minimized amount of fiber cable&accessories.

Less riser cables and termination boxes (lower CAPEX)Faster installation time Lower installation costEase of installationEase of maintenanceIdeal for narrow and densely populated shafts

We have a 12U wallmount rack at the main telecom room on the basement of the building. The incoming outdoor fiber cable of 24 core is spliced via a 24 port feeder patcpanel and connected to the OLT device to provide GPON fiber connectivity in this tower. We use a 2U Splitter Module with 5 pieces of 1:8 SC/UPC splitters to provide connectiv-ity for each 40 floors (5x 8). The interconnection between these splitters and the special flexible 48 core fiber tree cable is done by the 2U 48 port customer distribution ODF.

Functional Block Diagram

48 core fiber tree cable is installed alongside the entire shaft of the tower. On each 40 floors we installed a brancing kit on the shaft. We made a small cut on the 48 (12x4) core fiber tree cable and take a single core on each floor. This single core is protected inside the brancing kit, pulled out and directed via a cable protection tube to the 1:8 SC/PC Splitter ODB box, which is placed on the shaft . Thus we can provide connectivity for up to 8 subscribers on each floor from a single fiber core.

On the customer side we have 2 port customer termination boxes to provide fiber connectivity. 2 port bend insensitive drop cables are used to enable the connection between the 1:8 SC/PC splitter ODB on the shaft area and the 2 port cus-tomer termination box inside the customer premises. 2 port customer box is connected via patchcords to ONU devices to bring fiber connectivity inside the customer premises.
