The independentdesign authority foroptical & transmissionnetworks.
Survey to as-built for rail, metro and mission-critical urban telecoms. Vendor-neutral, buildable and engineered for first-time approval.
Every budget is engineered to worst-case, end-of-life margins. No product line to sell.
Numbers we will stand behind at sign-off.
A governed lifecycle, with sign-off gates.
Every package moves survey to as-built through a fixed sequence. Two stages are formal sign-off gates. Nothing proceeds to civils or handover until the LLD and the assurance case are signed.
Survey
Ground-truth route, ducts, chambers, reach.
IHLD / HLD
Topology, backbone routes, service sectors.
LLD
Splice packs, channel plans, chamber layouts, BoM, civils SLDs.
Sign-off gateAssurance
Link-loss, OSNR and GSNR proven to end-of-life margin under TfL and LU assurance.
Sign-off gateAs-built
Red-line capture, handover, O&M, close-out.
What we design.
Five service lines across the optical, transmission and IP estate, held to one assurance standard.
How we engineer a span.
Every span is budgeted event by event: connectors, fibre and splices, proven against the worst-case, end-of-life limit before anything is committed to civils. The same discipline carried the Connected London LLD packs through approval first time.
Proof from live programmes.
Renewing a live metro operational network with headroom for CBTC and ESN.
London Underground's Connect network is being renewed while carrying live CCTV, radio, SCADA and operational comms. We led the transmission and migration design of the fibre and SDH bearer, delivered the IP-CCTV migration and NMC integration, and engineered deliberate capacity headroom for future CBTC and Emergency Services Network services. It is a safety-of-life estate with no room for rework.
Advice with no equipment to sell.
Our budgets are engineered to worst-case, end-of-life margins across multi-vendor estates: Cisco, Juniper, Nokia and Arista today, plus the Alcatel-Lucent, Brocade and Ericsson systems still in the ground. You get advice you can take to assurance, with no OEM interest behind it.
No OEM allegiance and no reseller margin. The design serves the estate.
Splice packs, BoMs and civils a contractor can construct as drawn.
Numbers you can take to assurance, engineered to margins we will stand behind at sign-off.
Bring us in at survey, not at rework.
