Cabo drop FTTH DIGITUS DK-3904LCA-50-1 monomodo 4 fibras 4 LC/APC 50 m

DIGITUS DK-3904LCA-50-1 FTTH drop cable is a singlemode optical cable with four fibres and four LC/APC connectors on one end, supplied in a 50 m length. It is intended for fiber-to-the-home installations and short outdoor/indoor runs for point-to-point subscriber drops and premises handover. The cable uses G.657A2 bend-optimized singlemode fibre and a low-smoke, zero-halogen (LSZH) sheath for safer indoor use. A pre-assembled connector end reduces installation time and the open end is prepared for simple routing into a building distributor or floor termination point.

Advantages

The pre-assembled LC/APC connectors on one side significantly reduce on-site termination work and speed up deployment. G.657A2 bend-optimized fibres improve performance in tight routing and small bend radii common in premises and ducting. The cable design includes a Kevlar strength member and a sturdy pull-in loop to withstand pulling forces during installation while maintaining low insertion loss and high return loss thanks to APC polished connectors.

Suitable for (tasks / use cases)

• Subscriber drop lines from building distributor to apartment or premises
• Handovers and indoor FTTH terminations at network level 4
• Short outdoor/indoor ducts and trunking runs
• Environments requiring low back-reflection connectors (APC) and tight bend routing

How to use

Route the open end of the cable through the ducting or trunking to the building or floor distributor. Use the pre-assembled LC/APC connectors to terminate directly into subscriber sockets, patch panels or adapters at the handover point. During installation, use the pull-in loop integrated in the cable to assist feeding without stressing the fibre. Ensure connectors and ports are clean before mating to maintain the specified insertion and return loss values.

Recommendations

Maintain the specified minimum bending radius during installation and avoid sharp bends. Use appropriate conduit, trunking and strain relief to protect the cable when pulling and fixing. Clean LC/APC connectors with a suitable fibre inspection and cleaning tool before connection and verify link performance after installation.
