Optical fiber redesign and leasing out of

Optical Dark Fibers

KMRL undertook an exercise for strategic
improvement to optimise the performance of its

telecommunication network and generate additional

revenue. The initial design involved terminating
optical fibers at each station's Optical Distribution

Frame (ODF) using patch cords. This approach

caused in significant optical power loss, hindering

network efficiency.

To address this issue, our in-house team redesigned

the fiber optic network. This involved a critical

change.Implementing direct splices between stations.
Instead of terminating fibers at every station, they are

now directly spliced from the starting station to the

end station, eliminating unnecessary connection
points. Additionally, fiber terminations within all

station ODFs were respliced to ensure optimal signal

flow.

This redesign yielded two significant benefits. Firstly,

it drastically reduced optical power loss, leading to a

more robust and efficient telecommunication network.

Secondly, it created end to end "dark fibers" within
the redesigned network. These dark fibers can now

be leased to external agencies like Telecom Service

Providers (TSPs) and Internet Service Providers
(ISPs). KMRL has already successfully leased out a

total of seven pairs of dark fibers, generating a

considerable additional revenue stream. This
innovative approach demonstrates KMRL's

commitment to both operational efficiency and

maximizing the value of its infrastructure.
