SKY SYSTEM+

FIBRE OPTIC FTTH NETWORKS

OPTOMER engineers have developed an innovative FTTH Optical Fiber Aerial Networks system based on an Easy Access Cable without the need to use of splice boxes and cable reserve frames. The advantage of OPTOMER SKY SYSTEM + over existing solutions is a small number of system elements which reduces installation time and investment costs.

A development of fiber optic access networks is growing rapidly around the world. The access to broadband services is becoming an indicator of the level of development of a country. It creates a challenge to connect as many subscribers as possible in the shortest time. The connection must be reliable independently from the client’s location and should be done in the most economical way.

A detailed analysis of market needs had helped us to offer a groundbreaking solution. OPTOMER SKY SYSTEM+ (OSS+) is an answer to service providers’ needs. Thanks to a simple construction OSS+ is easy to design, cheap and fast in assembling. The idea allows to quickly connect new subscribers, both B2C and B2B. In addition, the system is flexible and can be fitted to any conditions. The range of the network built in OSS+ system is basically unlimited because each end can be extended to start a new network branch

Advantages of OSS+ compared to traditional aerial networks

OPTOMER SKY SYSTEM + is dedicated to networks built on poles. It is designed for both rural and urbanised areas. It is possible to design and build the network in the most optimised way and with the possibility to extend it in the future. In the traditional aerial networks based on poles it is necessary to use cable spare length frame even every second or every third pole.

A spare length of the cable is gathered in the frame, which enables conducting any kind of operations, such as splicing, on the ground. The placement and number of the frames must be predicted at the beginning of the investment, to enable network reconfiguration at the given point. However, the optical closure can be added to the already existing cable only at the time of connecting subscriber.

In such traditionally built networks the subscribers cable must me led from a scubscriber to the nearest closure. Very often it means leading many subscriber cables along with the riser cable. This solution strains the pole unnecessarily, increase the quantity of used material and costs of installation. What is more, each subscriber’s connections means opening an optical closure and preparing cable spare length once again. The installer also needs to think about the time needed for making a splice for each newly connected client.

To reduce expenses of building a traditional aerial network some companies decide to increase the distanec between optical closures. It lets to decrease the number of spare length cable frames, cable and closures used for installation. Surprisingly this can cause even higher load of all unfavorable factors mationed before. The necessity of using a higher number of cables and equipment with each new connection means that the total cost of installation is a lot higher that with the network where such “savings” were not used.

In OSS+ the distance between optical closures does not have any influence on the number of materials needed to connect a subscriber, because the client is being connected always from the nearest pole and there is no need to lead many cables along the cable track. It helps to optimize the access network in the way not reachable for the traditional aerial system.

OSS+ provides an unusual way of fibre management due to the fact that the subscriber’s fibre is already present in the riser cable used in the OSS+ system. IT eliminates the necessity of splicing for each new subscriber in the closure while connecting because all fibres are already spliced in the pole distribution box OSS+PSHN right at the beginning. Additionally, it is possible to use one module for 2 subscribers, because we can terminate both ends of the riser cable in the pole distribution box OSS+PSHN. When we cut a single module to connect the subscriber in one of the distribution boxes we free the fibre terminated in another distribution box. It can be used to provide the service to another subscriber or as a spare in case of any unexpected situations.

Pole distribution boxes OSS+PSHN are designed to be mounted relatively low, which eliminates the necessity of gathering spare length of fibre that is usually needed to take a distribution box from the pole. It also lets to save the time needed to connect a new subscriber (the installer does not need to climb a ladder to reach the splitter). It is still possible to gather spare fibre length in a distribution box, because it is integrated with a housing designed especially for this purpose. This outer housing can be quickly dismount to take the proper distribution box out to the.
