Oil Field SDH Telecommunications Network
Partnered with Loop to design and deploy a complete SDH/SONET telecommunications network connecting multiple geographically dispersed oil fields. The solution provided a high-speed STM-4 backbone between the two largest sites using Loop O9400R devices, with O9500 devices deployed at satellite locations — delivering both high-speed connectivity for modern infrastructure and low-speed DS0 access for legacy voice and telemetry equipment across the entire operation. See our communication systems and the guide to SCADA communication networks for remote sites.
- Geographically dispersed oil fields spread across remote desert terrain requiring a unified, high-reliability communications network for real-time operational data transfer
- Disparate site requirements — large, high-investment fields demanded high-speed connectivity while smaller legacy or near-depleted sites still relied on low-speed voice and data interfaces (DS0, FXS, FXO, E&M)
- Mission-critical resilience — the network had to guarantee continuous data availability with automatic failover and ring protection to prevent any single point of failure from disrupting field operations
- Legacy infrastructure integration — ageing oil fields carried existing low-speed telecommunications infrastructure that had to be accommodated without costly replacement
- Future scalability — the backbone architecture needed a clear upgrade path to handle increasing bandwidth demands as new fields come online or existing operations expand
- Deployed Loop O9400R devices to form the critical STM-4 backbone between the two largest sites, with Subnetwork Connection Protection (SNCP) for resilient ring connectivity and MSP 1+1 line protection for automatic failover

Power Utility Teleprotection Interface Solution
Delivered end-to-end planning, design, solution specification, equipment procurement, and remote commissioning for a power utility facing critical teleprotection communication failures. Line Current Differential Relays (87L) were unable to communicate due to insufficient fibre availability — resolved by deploying Loop AM3440 hybrid multiplexers with custom-designed C37.94 optical interface cards to route protection messages over the existing E1 and SDH infrastructure. Read how teleprotection shapes network design in Designing SCADA communication networks for remote sites.
- Line Current Differential Relays (87L) unable to communicate with each other due to insufficient available fibre optic capacity across the power utility network
- Protection relays required standard or customised C37.94 optical interfaces for message conversion, but only customised interfaces were available — limiting compatibility with off-the-shelf teleprotection equipment
- Finding a teleprotection device with a matching customised optical interface capable of integrating with the existing E1 and SDH infrastructure

See our communication systems and how SDH, MPLS and radio compare for SCADA.
- Expanding and upgrading an existing metro railway line required a unified communications backbone capable of carrying alarm, security, and passenger information from every station back to central headquarters
- Diverse data types — the network had to simultaneously transport SCADA telemetry, security camera feeds, passenger information (bulletin boards, timetables, video advertisements), legacy telephone traffic, and dry contact alarm signals
- Integration of modern high-speed Ethernet services alongside legacy low-speed interfaces (traditional telephony and dry contact alarms) on a single converged platform
- Centralised monitoring requirement — all station data had to be aggregated at headquarters into unified interfaces enabling rapid response to abnormal events such as natural disasters, criminal activity, or high passenger traffic
- Network management simplicity — the operator needed an intuitive management platform that did not require large, complex NMS software for what was a focused, purpose-built railway network
- Deployed an STM-16 ring using Loop O9400R SDH nodes to form a resilient, high-capacity communications backbone connecting every station along the metro line
- At each station, the O9400R drops into Ethernet lines feeding SCADA systems, security cameras, and passenger information displays including bulletin boards, time schedules, and video advertisements
