The difference between broadband and fibre technologies

Posted on 7 May 2019 by Beaming Support

If you are comparing broadband and fibre technologies available to your business and want to understand how each would connect your business to the internet, this guide shares the different terminology, how each technology is set up, the speeds available and service levels available.

FTTC – Fibre to the Cabinet

Also known as: Superfast Fibre Broadband, Superfast Broadband, Fibre Broadband and advertised by BT Retail as Infinity.

How FTTC connects businesses to the internet:

  • Although this is often called fibre, it is in fact copper to the premises from the green cabinet.
  • Fibre is delivered to the green cabinet (pcp – primary cross-connection point) and then copper is delivered to the DP (distribution point) and into the premises.
  • Can be delivered via underground duct or copper wires from telephone poles.
  • Uses the BT Wholesale broadband network (shared bandwidth) with multiple points of failure and asynchronous bandwidth (higher download than upload).
How FTTC broadband works

Installation:

  • Requires a PSTN line rental and VDSL broadband router connected to the telephone socket and the service is associated with a telephone number.
  • Lead time is usually within 2 weeks from point of order and can be ordered at the same time as the telephone line or added to an existing telephone line.
  • The service can be migrated to another provider.

Speeds:

  • Speeds will vary depending on the length of the copper line from the green cabinet.

Service Levels:

  • Fix time SLA – standard 2 working days repair for the broadband, different service levels available for the PSTN line.

 

FTTP – Fibre to the Premises

Also known as: Ultrafast, Fibre to the Home (FTTH).

How FTTP connects businesses to the internet:

  • Fibre to the home or office from the nearest green cabinet.
  • Can be delivered underground in ducts or overhead from poles.
  • Uses the BT Wholesale broadband network (shared bandwidth) with multiple points of failure and asynchronous bandwidth (higher download than upload).
  • There is no associated PSTN line rental and the router needs to support PPPoE (Point to Point Protocol over Ethernet) on the WAN interface.  The router is connected to the Openreach supplied Optical Network Termination (ONT) device.
What is FTTP?

Installation:

  • Requires a survey so takes longer to install than FTTC but it can be migrated between ISP’s.
  • The service does not include a telephone line or number.

Speeds:

  • Comes in different speeds for cost reasons but not dependent on line length and the speed can be upgraded if available.

Service Levels:

  • Fix time – standard 2 working days.

 

Dedicated Internet Fibre

Also known as: Fibre Ethernet service, Fibre Optic Leased Line, Dedicated Internet Access or Direct Internet Access.

How Dedicated Internet Fibre connects businesses to the internet:

  • A dedicated ethernet fibre to the business premises is delivered usually via duct (but sometimes via aerial fibre) from the nearest serving exchange.
  • Dedicated synchronous Internet bandwidth  that is not shared with any other client.
How fibre optic leased lines work

Installation:

  • The lead time is usually 30 working days for installation provided there are no additional civil engineering Excess Construction Costs (ECC’s).
  • Installation costs vary according to the engineering work required (ECC’s) which is determined at survey by an Openreach engineer who visits the premises.
  • The service does not include a telephone line or number and cannot be migrated to another provider.
  • Openreach fibre terminating equipment is either wall mounted or rack mounted into the customer comms cabinet.
  • Customer interface presentation from Openreach has options to be either Ethernet RJ45 up to 1Gbps, Single Mode Fibre (SMF) or Multi Mode Fibre (MMF).

Speed:

  • The fibre to the premises is usually known as the Bearer and this comes in variants of 100Mbps, 1Gbps and 10Gbps.
  • Customers may choose to have dedicated bandwidth in increments up to the bearer size.
  • If bandwidth bearer capacity exists then customers can upgrade their bandwidth usually within a few days.

Service Levels:

  • Fix time – four hour response, five hour fix regardless of day or time.

 

Dedicated Fibre – Point to Point

Also known as: fibre Ethernet service, leased line or possibly private circuit.

How Point to Point connects business premises:

  • Dedicated Ethernet fibre between two business premises delivered usually via underground duct (but sometimes via aerial fibre) from the local serving telephone exchanges.
  • Typically used to link two customer buildings together at very high speed so that staff can operate at the same speeds as if they were located in the same premises.
  • There is no internet access on a point to point fibre service.
How point to point fibre works

Installation:

  • Installation costs vary according to the engineering work required (Excess Construction Costs – ECC’s) which is determined at survey by an Openreach engineer who visits the premises.
  • The lead time is usually 30 working days for installation provided there are no additional ECC’s.
  • The service does not include a telephone service or number and cannot be migrated to another provider.
  • At the A-end premises Openreach will also install their own monitoring line and broadband.
  • Openreach fibre terminating equipment is either wall mounted or rack mounted into the customer comms cabinet.
  • Customer interface presentation from Openreach has options to be either Ethernet RJ45 up to 1Gbps, Single Mode Fibre (SMF) or Multi Mode Fibre (MMF).

Speed:

  • Maximum radial distance between customer premises is 45km for up to 1Gbps services and 25km for 10Gbps.
  • Maximum route distances of fibre is 86km for up to 1Gbps services and 40km for 10Gbps.

Service Levels:

  • Fix time – four hour response, five hour fix regardless of day or time.
