Patchcord Extralink SC/APC–SC/APC singlemode Simplex G.657A1 3 mm 2 m

Patchcord Extralink SC/APC–SC/APC singlemode Simplex G.657A1 3 mm 2 m is a singlemode fiber optic patch cord with SC/APC connectors on both ends. The cable uses bend‑insensitive G.657A1 fiber in a simplex configuration with a 3 mm outer jacket and a 2 m nominal length. It is intended for optical patching and interconnection of network equipment in FTTH, telecommunications and data network installations where low‑loss SC/APC terminations are required.

Advantages

The patchcord provides low insertion loss and stable optical performance due to factory‑polished SC/APC ferrules and singlemode construction. Bend‑insensitive G.657A1 fiber improves performance in confined routing and tight bend situations, reducing sensitivity to microbends. The 3 mm jacket offers mechanical protection and flexibility for installation in equipment racks, patch panels and customer premises wiring.

Suitable for

• FTTH installations linking OLT to ONU/ONT
• Optical equipment interconnection such as switches, media converters and transceivers
• Patch panels and distribution frames in telecom and data centers
• Laboratory test setups and field fiber testing where SC/APC terminations are required

Key specifications

• Fiber type: Singlemode, G.657A1 (bend‑insensitive)
• Connector type: SC/APC on both ends (male ferrules, angled polish)
• Structure: Simplex (single fiber)
• Cable diameter: 3 mm outer jacket
• Nominal length: 2 m
• Typical use: Optical patching and equipment linking in FTTH and telecom networks

How to use

Connect one SC/APC connector to the output port of the transmitting optical device and the other SC/APC connector to the input port of the receiving device, ensuring proper alignment and full insertion until a tactile click is felt. Avoid rotating angled connectors during insertion to preserve the APC polish orientation. Route the cable to avoid sharp bends tighter than recommended for G.657A1 fiber and secure it with appropriate cable management accessories to prevent tension or repeated bending that could affect attenuation.

Usage recommendations

Before installation, inspect connector endfaces for contamination and clean with suitable fiber cleaning tools if required. Use proper strain relief and avoid tensile loads beyond the cable’s rated handling limits. For permanent installations, verify link loss with an optical power meter or light source and keep connectors capped when not in use to maintain low loss and long service life.
