Splice at the Van, Not at the Wall
BDFB Access Building Terminal — Survey-free FTTH deployment for single-family, multi-dwelling, and building distribution. Mount the box, bring the slack to your splicing van, and connect without ever knocking on a door.
Zero-Intrusion Installation & Maintenance
Measure Once, Cut Never
Eliminate the costly pre-deployment survey phase. Because BDFB terminals store excess cable on-board, installers do not 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.
Bring the Slack to Your Workbench
Modular integrated spools provide 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 in harsh weather or difficult-to-access mounting locations.
Outdoor Mount, Indoor Access
The BDFB mounts externally (IP65-rated) while providing protected internal space for splicing and active equipment. Technicians perform MACs and troubleshooting from the outside, eliminating appointment scheduling and access coordination. The building occupant never knows you were there.
The Backplane Principle
Three fixed footprints (Small, Medium, Large), one flexible philosophy. Interchangeable backplanes transform each box for direct splicing, splitter distribution, tap configurations, WiFi AP mounting, or ONT integration. Configure for the application, not the logistics chain.
Three Steps to Survey-Free Service
Step 1: Mount Mount the BDFB terminal on the exterior wall. No resident required. The IP65 enclosure survives facade conditions.
Step 2: Pull & Splice Draw the fiber slack to your van using the integrated spool. Perform precision fusion splicing in controlled conditions, away from the wall.
Step 3: Reel & Close Reel back the excess cable onto the spool. Close the terminal. Service is live without ever knocking on the door.
One Box. Five Personalities.
Direct Splicing Fiber-to-fiber fusion or mechanical splicing. No splitter. Pure pass-through connectivity.
PLC Splitter Planar lightwave circuit integration. 1×2 or 1×8 splitter options for point-to-multipoint distribution.
Tap Configuration Asymmetric tap ratios for shared infrastructure: 90/10, 85/15, 80/20, 70/30, and 60/40.
Pre-Terminated Compatible with hardened connector assemblies for plug-and-play drop cables.
Active Equipment WiFi AP mounting kit and ONT accommodation with engineered heat dissipation and cable management (L model only).

Deployment Scenarios
Deploy fiber to single homes without scheduling conflicts. Mount the compact S-terminal on the exterior wall during the day. 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.
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.
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.
