Fiber optic cable is often used as a backbone: between a main equipment room and intermediate rooms, between floors, across a warehouse, or, on larger sites, between buildings. The work can include placing the cable, terminating or fusion-splicing strands, dressing them in a panel, and testing. Multimode fiber (commonly OM3 or OM4 in buildings) and single-mode fiber serve different distances and equipment. The partner who surveys your site should match the plant to the owner’s equipment and to any specification already in the bid documents. Metroplex Cabling does not design optical networks and does not recommend a product line.

Indoor backbone first
The public pages on this site lead with indoor commercial fiber: equipment-room to equipment-room, floor to floor, and warehouse spans inside a building. Outside-plant work in a city street or right-of-way is a different kind of job, with different registrations, bonds, and insurance. If a project leaves the building, the partner has to confirm what the city requires. This site does not advertise residential fiber-to-the-home service, and it is not a place to order a consumer internet plan.
Published typical ranges, not a bid
Z-Tech Communications’ Dallas-area guide dated December 10, 2025, listed a fiber optic backbone at $3,000 to $5,000 and up, varying by strand count. That line is a useful local starting point and, as that guide notes, can understate larger scopes.
Capital Techies, in a 2026 fiber installation guide written from a mid-Atlantic contractor’s perspective and not specific to Dallas, published these broader ranges: indoor fiber, installed, about $1 to $6 a foot, plus about $25 to $60 a termination and $30 to $75 a fusion splice; building backbones often $5,000 to $30,000; a 12-strand OM4 refresh from a main room to two intermediate rooms over three floors $8,000 to $15,000; a 600-foot warehouse span $4,000 to $9,000; campus building-to-building work, including directional boring, $15,000 to $75,000 and up. Treat those as national context beside the Dallas backbone figures, not as a Metroplex bid. Full citations are on the cost guide.
Testing and closeout
A professional fiber job is usually documented with optical testing, often including an optical time-domain reflectometer (OTDR) trace and power-meter readings, plus labeling and as-built notes. Ask the visiting contractor what reports they will provide and who honors a workmanship warranty. Those deliverables come from the partner, not from this website.
