Fiber optics is the infrastructure of choice in 5G networks.

The challenge of managing Fiber Optic Infrastructure in 5G

5G networks are expected to support high bandwidth, lifesaving applications such as autonomous cars, remote medical operations, M2M and IoT, therefore, the perceived network availability has to be 99.99%. To achieve such high availability, extensive fiber networks are deployed, and all network elements must be backed up.

Automating the 5G backhaul with TeliSwitch AODF and EMS is extremely beneficial due to fast failure recovery and downtime reduction of the optical layer. The result is improved network availability and OPEX reduction.

AODF ensures the second-order survival of the optical infrastructure. First-order survival is guaranteed by the electro-optical equipment operating in two lanes but in the event of a malfunction in the equipment or optical infrastructure, there is no backup for traffic and then the AODF allows a fast connection of an alternative route that is used as a second backup until the fault is repaired.

TeliSwitch AODF & EMS reduce both deployment and operation costs. Fiber links established with AODF can be tested at a single location, utilizing AODF loopback capability. This is in contrast with present practices engaging teams at fewer locations. Fiber link integrity can be verified by an automated session, where OTDR is switched to various ports in sequence, relieving technicians of this tedious end error-prone job.

Once deployed, AODF need not be ever visited, unless a major fault occurs. Connections are configured remotely as needed. This allows less accessible and safer deployment, protecting the assets from unintended or malicious harm.

Zero maintenance

Once deployed, AODF need not be ever visited, unless a major fault occurs. Connections are configured remotely as needed. This allows less accessible and safer deployment, protecting the assets from unintended or malicious harm. The diagram below presents how the AODF unit is implemented at the 5G backhaul network. The AODF back-up the optical cables of the Backhaul network and the optical cable from the aggregation point to the cells, assign alternate links upon failure, enables fast restructuring of the physical layers to meet network evolvement.
