Construction of a data transmission network for connectivity between JASEC buildings, reclosers and remote metering collectors of the electricity distribution network.

Location: Cartago – Costa Rica

No. of inhabitants of the town/area: 160,000 inhabitants / 70,000 dwellings

Date: 2010-2012

Client: Administrative Board of Electrical Services of Cartago (JASEC)

Project description: The FTTH network built in the coverage area was a benchmark infrastructure in Central America as it was the first FTTH network deployment in the region in an “Open Access” open operator model.

The executive deployment project covered the Cartago area, initially passing 46,080 residential units and connecting 4,200 customers in the first phase. This infrastructure was scalable to 70,000 homes without modifying the existing routes.

For this project, a Fiber to the Home (FTTH) access solution was designed, engineered and delivered, enabling the transparent distribution of triple play voice, data and video services to single family homes, blocks of flats and businesses over the fibre to the home network.

The deployment engineering was carried out after extensive field work to determine the residential units in each zone of the coverage area, in order to have the exact number of customers to be connected. The design was customised for each zone to minimise the material count for maximum efficiency. This ensured minimal future maintenance.

In addition, the project included the connection of the reclosers and remote metering collectors to JASEC’s electrical distribution network and also the connection of JASEC’s various corporate buildings to reduce the cost of connecting their existing telecommunication services.

All of this was carried out with the utmost excellence, using top quality carrier-class specification materials and electronics, offering a 99.999% service level, to achieve optimum results and deploy a long-distance infrastructure with minimum operating costs that placed JASEC as a benchmark in the operation of ultrafast networks throughout the Central American region.

Thus, with the proposed FTTH solution, voice services (POTS, E-1, VoIP), data services (10/100/1000 Ethernet, E-1) and video services (IP video, RF broadcast in Analogue/Digital for CATV and DBS) can be offered within a single single fibre optic network.

Enablence’s FTTH access solution was used because it is a universal platform that offers Point-to-Point Metro Ethernet, ITU G.984 GPON and IEEE 802.3 GE-PON (EFM PON) services over the same platform.

Additionally, it has two chassis to offer the connectivity services, a compact one (COLT) and a high capacity rack, called OLT Trident7. This makes the solution very flexible and the deployment costs can be optimised very effectively.

Regarding the network management, an open and fully documented solution was proposed, with “Flow-Through” capabilities, offering provisioning, remote updating and monitoring services for all elements of the access network, as well as full integration with the alarm manager.
