§01
The practice

An independent network design authority.

Chroma Networks exists because the hardest telecoms estates deserve design work that survives contact with assurance, contractors and time. The practice was built inside rail, metro and mission-critical London telecoms, where a drawing either constructs cleanly or costs a possession.

We are a design authority, not a body shop. Engagements carry one accountable senior engineer from survey to as-built, and every number in the pack is one we will defend at sign-off.

The practice also writes software. The same design rules we apply by hand are encoded into IQGeo, QGIS and bespoke tooling, so quality is repeatable rather than heroic.

Principal · Network Design Authority

Chroma Networks is an independent optical and transmission network design consultancy for rail, metro and mission-critical urban telecoms. We carry designs from survey through IHLD, HLD and LLD to as-built, pairing DWDM, OTN and SDH transport engineering with expert IQGeo and QGIS tooling and design-rule automation. The practice draws on 25 years across LU Connect, the Elizabeth line and TfL Connected London. Our packs are buildable as drawn, our advice is vendor-neutral, and our Connected London LLD packs were approved first time.

Engagement

Four ways to engage.

Design authority

Owner-side or integrator-side authority for transmission and fibre design, with assurance-ready documentation.

Detailed design

Survey to as-built delivery of LLD packs, splice packs, BoMs and SLDs that construct as drawn.

Assurance & audit

Independent review of designs, margins and data quality before they reach an assurance panel or a contractor.

Tooling & automation

IQGeo and QGIS configuration, rules engines and data QA pipelines built for your design office.

Bring us in at survey, not at rework.
