Fiber-patchkabel Extralink SC/APC til LC/UPC, singlemode G.652D, 3 mm, simplex, 20 m

Extralink single-mode fibre patchcord with SC/APC connector on one end and LC/UPC on the other provides a 20 m simplex link for low-loss optical signal transmission. The cable uses G.652D single-mode fibre in a 3 mm jacket, designed for patching, equipment interconnection and FTTH installations where a reliable single-mode connection between devices is required. This patchcord supports standard telecom and data network applications and is suitable for connecting switches, media converters, OLTs and ONUs/ONTs in access and distribution environments.

Advantages

This simplex SC/APC to LC/UPC patchcord delivers low insertion loss and stable single-mode performance due to the G.652D fibre construction and precision-terminated connectors. The combination of SC/APC and LC/UPC terminations enables versatile compatibility with common rack and wall-mounted equipment while preserving optical return loss characteristics. The 3 mm jacket provides physical protection for routine handling and routing without adding excessive bulk, and the 20 m length covers moderate distance runs within equipment rooms, wiring closets and FTTH premises.

Suitable for

• Interconnecting optical equipment such as switches, media converters and transponders
• FTTH connections between OLT and ONU/ONT devices
• Patch panel to equipment links in telecom and data centre environments
• Laboratory tests and temporary fibre runs where a single-mode simplex link is needed

Key specifications

• Fibre type: single-mode, compliant with G.652D
• Connector A: SC/APC (angled physical contact)
• Connector B: LC/UPC (ultra-physical contact)
• Cable construction: simplex, 3 mm outer jacket diameter
• Length: 20 metres
• Typical use: single-mode optical patching for telecom and FTTH

How to use

Identify the required ports on your devices and insert the SC/APC and LC/UPC connectors into matching adapters or receptacles, ensuring the angled APC end is mated with an APC port and the UPC end with a UPC port. Avoid excessive bending; follow the manufacturer’s minimum bend radius for single-mode fibre when routing the 3 mm cable. Secure the cable along trays or within cable management to prevent strain on connector ferrules and maintain stable optical performance.

Recommendations

Clean connector endfaces before installation using appropriate fibre cleaning tools and inspect ferrules with a fibre scope. Store and route the patchcord without sharp bends or kinks; maintain gentle loops and use cable ties or Velcro straps without over-tightening. For best optical results, match APC connectors to APC ports and UPC connectors to UPC ports to avoid return loss issues.
