BDFB Access Building Terminal — The survey-free FTTH deployment solution.

SlimRun Jet — The aerodynamic fiber Ferrule engineered for micro-duct blowing.

Mount the box, bring the slack to your splicing van, and connect without ever knocking on a door. Zero-intrusion installation and maintenance for single-family, multi-dwelling, and building distribution scenarios.

Van-Optimized Splicing

Zero-Intrusion Maintenance

Bring the Slack to Your Workbench

Why crouch at a wall when you can splice in comfort? The BDFB family features modular integrated spools providing 8m (S/M) to 30m (L) of cable slack storage. Pull the fiber to your fully-equipped splicing van, perform precision fusion in controlled conditions, then reel back the excess. Faster installs, better splice quality, and happier technicians—especially critical in harsh weather or difficult-to-access mounting locations.

Measure Once, Cut Never

Eliminate the costly pre-deployment survey phase. Because BDFB terminals store excess cable on-board, installers don’t need to pre-measure drop lengths or coordinate with residents to access interiors for splicing. Mount the terminal, pull the OSP cable, and manage the slack locally. Deploy to the wall first, splice when convenient—decoupling installation from connection reduces truck rolls and accelerates time-to-revenue.

Outdoor Mount, Indoor Access

Stop asking residents for entry. The BDFB mounts externally (IP65-rated) while providing protected internal space for splicing and—on the L model—active ONT equipment with engineered heat dissipation. Technicians perform MACs (Moves, Adds, Changes) and troubleshooting from the outside, eliminating appointment scheduling, access coordination, and the security concerns of indoor truck rolls. The building occupant never knows you were there.

The Backplane Principle

Three fixed footprints (Small, Medium, Large), one flexible philosophy. Rather than stocking dozens of SKUs, the BDFB uses interchangeable backplanes to transform each box size for your specific needs: direct splicing, splitter distribution (1:2 to 1:8), tap configurations (90/10 to 60/40), WiFi AP mounting, or ONT integration. Configure for the application, not the logistics chain. The spool itself is optional—add it when needed, omit it for tight spaces or pre-terminated drops.

Deployment Configurations

The "Invisible" Installation

Deploy fiber to single homes without scheduling conflicts. Mount the compact S-terminal on the exterior wall during the day—no resident required. Store 8m of slack on the optional spool, return to the van for precision splicing, and reel back the excess. The homeowner gets service without ever opening the door. Perfect for suburban and rural FTTH where density is low but deployment speed is critical.

Grow as You Go

Serve 8 apartments from one compact terminal without initial overbuild. Start with direct splices for early subscribers, then add the 1:8 splitter backplane as penetration increases—all without replacing the box or disturbing existing connections. The 8m spool accommodates the messy reality of MDU riser distances, allowing you to pull from the main distribution point to the basement terminal, then splice at street level in your van. Modular growth meets survey-free deployment.

The All-in-One Demarcation

Combine fiber distribution and active equipment protection in one IP65 enclosure. The L-series hosts ONTs up to 158×185×40mm with dedicated heat dissipation, eliminating the need for separate active equipment shelters. Use the 30m spool capacity to bridge from the building distribution point to distant entry points, or manage ribbon fiber splicing for high-count backbones. External mounting means building management never worries about technician access, while the integrated ONT protection ensures active equipment survives harsh facade conditions.
