Why SP Telecom?


Diversity & Coverage

Offering You Unique Diverse Path Into Your Building SP Telecom’s fibre network is one of the most diverse and extensive in Singapore. We are the only operator with this unique network topology, running alongside SP Power Grid. SP Telecom enters buildings differently, offering a unique and diverse path. SP Telecom manages and owns its backhaul, and leverage its parent’s power substation assets, manhole and lead-in pipes into the buildings.

Security & Reliability

SP Telecom pipes are fortified with layers of concrete slabs, along with electromagnetic field detectors to provide added protection. The width of the concrete slabs exceeds the cable pipes’ width placed underneath. When pipes are under concrete, this is a deterring sign to personnel working or excavating nearby. It also acts as a physical barrier against potential accidental damage to buried cables, eliminating costly loss of productivity and repairs. This security feature enhances the reliability of service SP Telecom provides. Whether the shortest path or more complex options are needed, enterprises choose SP Telecom as a partner they can trust.
