MJ DATA LLC dba MJ Data Optics LLC

MJ Data Optics is a turnkey fiber optic construction and splicing company based in Navarre, Florida, serving ISPs, municipalities, and prime contractors across Florida, Georgia, Colorado, Wyoming, South Dakota, and beyond.

We handle the full build sequence under one team: directional drilling, underground and aerial cable placement, fusion splicing, OTDR and OLTS testing, and 24/7 emergency fiber restoration. That means no handoffs between separate drilling, placement, and splicing vendors, and no gap in accountability when the field doesn't match the plan.

Owner Mike Jauca oversees every project from plan review through final testing, bringing full-cycle hands-on experience across every phase of OSP construction. When a field condition creates a problem, the person who catches it is the same person who built it and can fix it.

We work as a subcontractor or direct partner on FTTH deployments, network expansions, route upgrades, and emergency restoration. If you are scoping a fiber build or need a reliable construction partner for an active project, contact us to discuss your scope.
