Additional Services

The LINX multilateral route servers are provided to all members free of charge. There are 2 of these servers on each of the LINX London peering LANs for additional resilience. Almost 65% of LINX members peer using this method advertising over 70,000 routes. LINX Manchester, LINX Scotland, LINX Cardiff and LINX NoVA also have route servers available to their members.

LINX operates a route collector on each Peering LAN. These serve primarily as a monitoring and troubleshooting tool for both LINX and our members. It is mandatory for each member to have a peering session with the collectors. Members can access the collector data through the looking glass service, that is accessible through our member portal. 

Bi-Directional optical transceivers are available for use at the LINX IXManchester exchange. They enable members to double their network capacity at no extra cost when connecting to the London Internet exchange most members will connect using a fibre pair or cross-connect. One fibre is dedicated to receiving data from network equipment and the other fibre will be dedicated to transmitting data to the network.  Bi-directional optical transceivers (or BiDi transceivers for short) allow the transmitting and receiving of data on a single fibre.  There is no additional charge for using BiDi transceivers, other than a £200 installation charge.

BiDi transceivers split light into different wavelengths using wave division multiplexors (WDM). They must work as a matched pair having the correct receive and transmit wavelength. A usual naming convention has one device referred to as upstream and one as downstream. For delivery of the LINX BiDi product LINX will always be the downstream device. The member will have to purchase the corresponding upstream device.


If you are interested in ordering a BiDi tranceiver please complete the new/upgrade order form and in the “additional information” box please state that you require BiDi optics.

LINX provides three Meinberg stratum 1 NTP Servers for members’ use. This is available to all LINX members including those who are connected to LINX Manchester, LINX Scotland, LINX Cardiff and LINX NoVA.

The LINX stratum 1 time servers distribute high accuracy time, derived from a variety of time sources (GPS, DCF77 and MSF signals)

The servers are available for members to syncronise their own NTP servers with, which in turn provide a Stratum 2 NTP server for their internal network and customers (Rather than using the LINX NTP servers directly for every device/customer).
