Questions we hear most.
About working with us, and about fiber networks in general. If your question isn’t here, ask an engineer.
Working with us
Scope, quotes and handover.
What does City Networks do?
City Networks is a telecom and information technology company based in Riyadh, Saudi Arabia. We design, supply, install, test and maintain fiber optic networks, supply passive fiber products, and develop software and websites. Clients can contract one service or the whole chain from design to support.
Where does City Networks work?
We are based in Riyadh and take on projects across the Kingdom of Saudi Arabia.
Who do you work with?
Telecom operators and their contractors, real-estate developers, consultants, and organisations that run their own private fiber networks. We take on complete projects or single stages inside a larger contract.
Can I hire you for just one stage of a project?
Yes. Design, supply, installation, testing and maintenance can each be contracted on their own. For example, we can test a network another contractor built, or supply materials to your own installation team.
Do you sell fiber optic products without installation?
Yes. Every product line in our catalogue can be supplied on its own, to your bill of quantities or specification.
How do I get a quote?
Send your requirements through the contact form or by email to Sales@citynetworks.co. Include the location, the scope, any drawings or bill of quantities, and your timeline. An engineer reviews it, contacts you to clarify the scope, and sends an itemised proposal.
What standards do you build to?
Each project is built to its approved design and to the specification of the operator or consultant responsible for it. Materials are globally certified, and installation and testing follow international industry standards.
What documents do I receive at handover?
A test report for every link, as-built drawings marked up from site, and the material documentation submitted for approval.
Fiber basics
How fiber networks work.
What is FTTH?
FTTH, or fiber to the home, is a network in which optical fiber runs all the way from the operator’s exchange to each home or unit, instead of switching to copper for the last stretch. Most FTTH networks use passive optical network (PON) technology, where unpowered splitters share one exchange port between many homes.
What is a passive fiber network?
A network in which everything between the exchange and the customer is passive: cables, splitters, closures and connectors, with no powered equipment in the field. It costs less to run and has fewer points of failure, which is why it is the standard design for FTTH.
What does it cost to build a fiber network?
Civil works such as trenching, ducting and reinstatement usually drive the cost, followed by labour and materials. Route length, ground conditions, whether existing ducts can be reused, and the number of premises matter far more than the price of the cable. A survey and design give a reliable figure, and we price from those.
How long does fiber optic cable last?
Properly installed and protected fiber cable is designed for a service life of 25 years or more. In practice, networks fail at closures, connectors and points of third-party damage long before the glass itself wears out.
What is the difference between OTDR testing and insertion loss testing?
An insertion loss test measures how much light is lost from one end of a link to the other, giving one accurate figure. An OTDR test analyses light reflected back along the fiber and shows where each splice, connector and fault sits and how much loss it adds. Most acceptance specifications ask for both.
