FTTX handholes

Reliable protection underground

The Microfocus Compact Access products are universal cable- and tube-storage boxes that can be directly buried, and that are especially developed for Access closures like EDSA, TENIO, and OFDC. The handholes are robust, equipped with a closable lid and made of durable polyethylene. The handhole serves as a mechanical protection of optical fiber cable and/or tubes, and the closure. It also ensures good accessibility of the closure in case of future client-connections. In addition, during the engineering phase the handhole can be equipped with extra length of tubes, or with client-cables that can be directly buried (DAC). The Compact Access products are available in a double-skinned version (ZTTH-series) or a single-skin version (UDP). These products are mainly applied in FTTH- and FTTB-networks or for events where a temporary hook-up with an optical fiber network is necessary.


The Compact Access products are suitable for installation on locations according to the European standard EN 124 groups 1 and 2. This under the condition that the Compact Access boxes are placed at least 600 mm under the surface.

  • Group 1: Areas that are only used by pedestrians and cyclists.
  • Group 2: Sidewalks, promenades and comparable areas, parking lots and driveways.

You decide

Since the application might vary per project, various models are on the market (see pictures):

  • Choice between ZTTH3 and 4, or UDP-casing.
  • Furnished without holes with connectors included, or ready for installation with pre-drilled holes. Diameters vary from 32 to 50 mm.
  • Temporary elevation-kit available.
  • If required available with lock.
  • The ZTTH is available both with a plastic or a cast iron lid.
  • Optional alarm-detectors can be added.

Your advantages

  • Quality: A robust handhole for a long-term protection of your optical fiber material.
  • Accessible: Easily accessible for modifications or expansions of your optical fiber network, ideal for client-connections.
  • Convenient: Possibility to store extra length.
