Patch kábel Extralink LC/UPC – SC/UPC singlemode G.652D, simplex, 3 mm, 0,5 m

Extralink single-mode patchcord with LC/UPC on one end and SC/UPC on the other provides a simplex 0.5 m optical connection for indoor telecommunication and FTTH environments. The cable uses ITU‑T G.652D fibre with a 3 mm jacket, designed for low insertion loss and stable single‑mode signal transmission between optical devices such as transceivers, switches, media converters and patch panels. This compact 0.5 m length is suitable for short point‑to‑point links inside racks, enclosures or wall boxes where reliable, low‑loss connections are required.

Advantages

The patchcord offers low optical loss and consistent single‑mode performance thanks to the G.652D fibre specification. Its simplex construction and standard LC/UPC and SC/UPC polished connectors ensure compatibility with most telecom and datacom equipment. The 3 mm jacket provides mechanical protection for indoor routing while maintaining flexibility for neat cable management. Connector endfaces are factory‑polished to reduce return loss and improve link reliability in optical systems.

Suitable for

• FTTH subscriber connections between OLT and ONT/ONU devices
• Interconnection of optical transceivers, media converters and switches
• Patching between optical distribution frames and wall outlets
• Short point‑to‑point links inside equipment racks and enclosures

• Fibre type: single‑mode, ITU‑T G.652D
• Connector A: LC/UPC simplex
• Connector B: SC/UPC simplex
• Cable construction: simplex
• Jacket diameter: 3 mm
• Cable length: 0.5 m
• Application: indoor telecom and FTTH installations

How to use

Ensure both optical devices are powered down or follow hot‑swap safety procedures before making connections. Align the LC/UPC connector with the LC port and push until it clicks; insert the SC/UPC connector into the SC adapter or receptacle until it seats. Avoid excessive bending of the 3 mm cable; follow minimum bend radius guidelines for single‑mode fibre to prevent increased attenuation. After installation, perform a basic link test or optical power check to confirm acceptable insertion and return loss for the connection.

Recommendations

Store unused connectors with protective caps to keep endfaces clean. Use a fibre inspection scope and cleaning tools when reinstalling or troubleshooting connections. For permanent installations, route the patchcord through appropriate cable management and avoid tight bends or crushing forces to preserve optical performance.
