Patchcord SC/APC–SC/APC Singlemode Extralink G.657.A2 FTTH 3 mm, 2 m

Extralink Patchcord SC/APC–SC/APC Singlemode Extralink G.657.A2 FTTH 3 mm, 2 m is a 2-metre singlemode simplex fibre patchcord with SC/APC connectors on both ends. The cable uses G.657.A2 bend‑insensitive fibre designed for FTTH deployments and indoor fibre links. With a 3 mm outer diameter and a yellow/green colour scheme, it is intended for low-loss optical connections between ONT/OLT ports, GPON equipment, and patch panels where APC‑polished SC terminations are required.

Advantages

The bend-insensitive G.657.A2 fibre reduces signal loss in tight routing and small-radius bends typical of customer premises and installation ducts. SC/APC terminations provide a stable angled-polish connection that minimises back-reflection, suitable for GPON and other singlemode systems. The 3 mm jacket offers manageable flexibility and durability for indoor routing and patching, while the 2 m length is convenient for rack-to-equipment or wallbox-to-ONT connections.

Suitable for

When it may not be suitable

This patchcord is a simplex singlemode cable with SC/APC terminations and a fixed 2 m length; it is not suitable where multimode fibre or duplex paired cables are required. It may also be unsuitable for outdoor or direct-burial installations because the jacket is intended for indoor FTTH use and does not specify outdoor UV or water-resistant ratings.

Key specifications

How to use

Connect one SC/APC connector into the optical port on the ONT, OLT or patch panel and the other into the corresponding SC/APC adapter or socket. Ensure connectors are clean before mating to prevent contamination and signal loss; use a fibre connector cleaner or lint-free wipes and appropriate cleaning fluid. Avoid tight bends or crushing the cable during routing—although the G.657.A2 fibre is bend-insensitive, standard good practises for fibre handling should be followed. Secure the cable in cable management elements or tie points to prevent strain on connectors.

What to consider before purchase

Recommendations

For best performance, clean both SC/APC connectors before installation, avoid compressing the cable or bending it below the recommended radius for G.657.A2, and use appropriate adapters or panels for APC connectors to maintain low back-reflection in GPON and other singlemode systems.
