Patchcord Extralink LC/UPC - LC/APC Single-Mode Duplex 9/125 µm G.657A 2 m

Extralink Patchcord LC/UPC-LC/APC Single Mode, Duplex, 9/125um, G657A, 2m is a 2‑metre single-mode duplex fiber patch cable with 3 mm diameter, terminated with LC connectors (one end UPC, other end APC). It is designed for connecting optical devices such as switches, media converters, OLTs and ONU/ONT units in FTTH and other single‑mode networks.

Advantages

The patchcord provides reliable single‑mode transmission with 9/125 μm fiber and G.657A bend‑insensitive construction. Duplex LC terminations ensure compact, standardized connections; the 2 m length and 3 mm cable diameter make it suitable for rack and cabinet installations while preserving signal integrity. Connectors follow UPC/APC polishing types for low return loss where required.

Suitable for

• FTTH links between OLT and ONU/ONT devices
• Interconnection of switches and media converters in single‑mode networks
• Patch panels and rack-mounted optical equipment

How to use

Unpack the patchcord and inspect connectors for dust or damage. Insert each LC connector into the corresponding LC port on your optical devices (observe UPC/APC orientations if required by the equipment). Route the cable without tight bends and secure it to avoid strain. For in‑rack connections, allow gentle slack to prevent connector stress.

Recommendations

Keep LC connector endfaces clean and use appropriate dust caps when not in use. Avoid bending the cable below the manufacturer’s minimum bend radius and verify connector type (UPC vs APC) compatibility before connecting to prevent increased return loss.
