FAQ - About Local in-house Cabling for Dedicated Fiber Installations in Sweden

At Accessbolaget, we often encounter questions regarding in-house cabling for fiber connections. This FAQ aims to educate and guide you through the jungle of terms, best practices, and pitfalls that you, as a purchaser of WAN/Internet access services, should be aware of. This FAQ is intended for use under Swedish conditions.

What is a Local in-house Cabling network?

• An in-house cabling network consists of one or more optical fiber cables connected from the network owner's first connection point (ODF - Optical Distribution Frame) to the end user's site, usually in a network cabinet inside the company's premises.

When do I need a Local in-house Cabling network?

• In principle, a local cabling network is always required when you need a dedicated fiber connection for Internet or WAN communication. However, in some cases the network owner can deliver a customer-owned ODF directly to the user's premises. This is uncommon in standard commercial properties but common in data center environments.

Who is responsible for the Local in-house Cabling network?

• As a tenant in a commercial property, you can often use an existing building network already installed in the property. If a fiber network is missing or cannot be used, your operator can usually arrange the installation of one in connection with service delivery. Typically, neither the operator nor the property owner provides an SLA for the local cabling network. However, it is becoming more common for property owners to provide a structured tenant network for which they take responsibility-similar to electricity, water, and sewage.

What type of Local in-house Cabling network should be installed?

• Historically, various types of building networks have been installed, such as Cat5/6 copper cables and multimode fiber. As a general rule, a building network should always be of singlemode fiber type, and at least one fiber pair should be installed and terminated in an ODF on each side. It is recommended to install two fiber pairs (a total of four fibers) and have two of them spliced and terminated, leaving two spare fibers for future use.

There's already Local in-house Cabling network, why can't we use it?

• If there is an existing Cat5/6 network outlet or multimode fiber in your premises, it requires that the operator has active equipment installed in the telecom room where the incoming fiber terminates. The disadvantage is that you, as a tenant, often don't have access to that room, and your service will depend on the power supply in an area accessible only to property maintenance staff. This setup is common for broadband services, where the operator/service provider has a switch in the basement serving multiple tenants. In such cases, the operator/service provider is responsible for access and ensuring power availability.

Our office is located in an airport, hospital, or heritage-listed building, what should we consider?

• Premises located in airports, hospitals, or other security-classified environments usually have a regulated campus network. As a tenant, you'll often need to lease a building network connection from your operator. We frequently coordinate deliveries and relocations in such properties through our established contacts. For heritage-listed (K or Q classified) buildings, there are regulations governing how cables may be installed, which may limit your ability to establish a building network or internal distribution network within your premises.
