Fiber patchcord Extralink LC/APC – LC/APC, Single‑mode duplex 9/125 µm G.657.A1, 1 m

Extralink LC/APC – LC/APC single‑mode duplex fiber patchcord, 1 m, is designed for short optical connections in FTTH, telecom and data centre environments. The cable uses 9/125 µm G.657.A1 bend‑insensitive single‑mode fiber and LC connectors with APC polish on both ends, providing stable, low‑loss connections for patch panels, ONT/OLT links and intra-rack fiber routing. The 3.0 mm outer diameter jacket gives a balance of flexibility and mechanical protection suitable for standard patching trays and cabinet routing.

Advantages

The APC‑polished LC connectors reduce back reflection for improved signal integrity, especially in passive optical network (PON) and high‑speed telecom links. Bend‑insensitive G.657.A1 fiber maintains low attenuation around tight radii, which helps preserve performance in constrained routing paths. Duplex LC termination provides reliable polarity and duplex communication in a compact form factor compatible with modern patch panels and optical equipment.

Suitable for

• FTTH subscriber connections between ONT/ONU and patch panels
• Short intra-rack or intra-cabinet fiber links in data centres
• Patch panel or chassis connections in telecom and enterprise networks
• Interconnection between optical switches, converters and media converters

Key specifications

• Fiber type: Single‑mode G.657.A1 (bend‑insensitive)
• Core/cladding diameter: 9/125 µm
• Connector type: LC/APC to LC/APC duplex
• Polish: Angled Physical Contact (APC)
• Cable diameter: 3.0 mm
• Length: 1 m
• Mode: Single‑mode duplex

How to use

Route the patchcord through cable managers or trays to avoid sharp bends and secure it with appropriate clips or Velcro straps without excessive tension. Insert each LC connector into the corresponding LC/APC port until it clicks, maintaining correct duplex polarity. For removal, press the LC latch and gently pull the connector straight out. Keep connector end faces covered with dust caps when not in use to prevent contamination and follow standard fiber safety procedures when working near live equipment.

Recommendations

Inspect and clean connector end faces with approved fiber cleaning tools before installation. Maintain minimum bend radius according to G.657.A1 recommendations and avoid repeated tight bending to preserve low attenuation. For permanent installations, use professionally terminated and tested patchcords and verify link performance with an optical power meter or OTDR as appropriate.
