HADD-Evo Hardened Access Terminal — GR-771-certified ruggedness with proprietary 11.5mm UMHA assemblies.
Deploy 30 hardened fibers (24 distribution + 6 cascade) in a terminal the size of competing 12-port units.
Pre-terminated, cascade-ready, and factory-tested for the harshest outdoor environments.
At just 11.5mm outer diameter, the UMHA assembliesis 32% smaller than other HE assembliesand nearly half the size of standard hardened SC (22mm). Designed and manufactured in-house by ADTEK, UMHA enables unmatched density: 30 ports (24 distribution + 6 cascade/pass-through) in our Large terminal versus the 12-port maximum of competing hardened terminals. Same GR-771 pull strength (450N), same IP68 submersion rating, significantly smaller footprint.
Unlike standard terminals that dead-end fibers, HADD-Evo features cascade ports—6 on the L-size (4 on M, 2 on S). Bring fiber in, split to 24 drops (via 3× 1:8 splitters), and pass fiber out to the next terminal. Daisy-chain from the Central Office through rural routes or MDU corridors without additional splice closures. The 6 cascade ports flex as inputs, outputs, or pass-throughs depending on your network topology.
Unlike splicing-based terminals that require vans, power, and skilled technicians, HADD-Evo arrives factory-terminated and tested. Installers simply mount the terminal (wall, pole, or strand), push-pull the assemblies into place with gloved hands, and verify with a simple optical check. No field polishing, no fusion splicing, no weather delays. Cut installation time by up to 70% compared to traditional splice closures.
Don’t let the small size fool you. UMHA assemblies and HADD-Evo terminals undergo the same Telcordia GR-771 and GR-3120 testing as the industry’s largest hardened terminals: 450N assemblies retention, 1.5-meter water immersion, -40°C to +75°C temperature cycling, and 95% humidity. The IP68 rating ensures submersible protection even in flooded hand-holes or hurricane-prone regions. Extreme retention mechanics keep connections secure against vandalism and accidental damage.

Low-density rural environments demand efficient fiber usage. The compact S-terminal with 2 cascade ports + 8 distribution ports enables true cascade architecture: signal enters, 10% or 20% is tapped off for the farmhouse, and the remainder continues to the next terminal. At just 265g and 30mm thin, it mounts discreetly on utility poles or strand-mounted without overload. The 11.5mm UMHA assemblies survive 450N pull forces during aerial installation, and IP68 protection handles ice, wind, and UV exposure. Deploy pre-terminated stub assemblies to eliminate field splicing in remote locations.
Serve 16 apartments from a terminal the size of a paperback book. The M-terminal’s 4 cascade ports + 16 distribution ports fit crowded telecommunications closets and utility alcoves where traditional 19″ cabinets won’t. Use 2 fibers in, 2 fibers out, and split to 16 drops (2× 1:8 splitters) for efficient MDU distribution. Pre-terminated with UMHA drop cables, installers complete connections in minutes—not hours. The toolless push-pull interface means no dropped screws in dark basements, and the tamper-proof design secures against unauthorized disconnection.
Achieve central office-level density at the building edge. The L-terminal delivers 30 hardened connections(24 distribution + 6 cascade) in a 230×219mm package that competitors limit to 12 ports. Ideal for large apartment complexes and rural cascade architectures: bring 3 fibers in, split to 24 drops (3× 1:8 splitters), and pass 3 fibers out to the next terminal. No splicing, no additional closures—just continuous hardened connectivity from the CO to the home.
