Comprehensive Scope of Engineering Execution
Circle 21 Innovation PVT LTD provided end-to-end design, civil conduit laying, optical fusion splicing, network switching, and server software deployment across Bangladesh Marine Academy Pabna.
1. Multi-Building Optical Fiber Backbone (2-Core & 5-Core)
Designed and implemented a ruggedized optical fiber distribution loop linking administrative headquarters, faculty offices, cadet academic blocks, and navigational training facilities. Deployed armored 2-core and 5-core optical fiber cables within impact-resistant conduits to ensure zero physical signal interference, moisture immunity, and low optical loss across extended campus distances.

2. OLT / ONU Configuration & FTTH Terminal Termination
Engineered and configured the central Optical Line Terminal (OLT) and distributed Optical Network Units (ONU). Executed high-precision optical fiber splicing and ONU termination at key campus nodes. Implemented dynamic bandwidth allocation (DBA), granular Quality of Service (QoS), and segregated VLANs to prioritize simulator telemetry and administrative database operations.
