Patch-kaapeli Extralink SC/UPC - SC/APC LSZH, yksimuotokuitu G.657B3, simplex 3mm Easy Flex, 15 m

Singlemode fibre patchcord Extralink SC/UPC - SC/APC, 15 m, designed for reliable indoor and FTTH optical connections. The cable uses bend-insensitive G.657.B3 fibre in a 3 mm Easy Flex simplex construction with SC/UPC on one end and SC/APC on the other. The LSZH outer sheath reduces smoke and halogen emission in case of fire, while the 15 m length and low-loss SC terminations make the patchcord suitable for connecting switches, media converters, optical line terminals (OLT) and customer premises equipment (ONU/ONT) in telecom and data networks.

Advantages

The Extralink patchcord combines bend-insensitive singlemode G.657.B3 fibre with a flexible 3 mm Easy Flex design to minimise signal loss at tight radii and facilitate neat routing in cabinets and indoor ducts. Using one SC/UPC and one SC/APC connector ensures compatibility with a wide range of optical devices and allows low-reflection mating where APC termination is required. The LSZH sheath provides improved safety characteristics in enclosed spaces by limiting smoke and avoiding halogen emissions under high temperatures.

Suitable for

• FTTH subscriber drop connections between OLT and ONU/ONT
• Indoor links between switches, patch panels and media converters
• Laboratory and test setups requiring a 15 m single-fibre jumper
• Telecom and monitoring equipment interconnections where low-reflection termination is needed

Key specifications

• Fiber type: Singlemode, bend-insensitive G.657.B3
• Connector type: SC/UPC to SC/APC, simplex
• Cable diameter: 3 mm Easy Flex
• Outer sheath: LSZH (Low Smoke Zero Halogen)
• Length: 15 m
• Construction: Simplex single-fibre jumper

How to use

Inspect connectors and ports for dust or damage before connection and clean with appropriate fibre-cleaning tools if necessary. Align and insert the SC/UPC and SC/APC connectors into compatible ports until they click into place, being mindful that UPC and APC ferrules have different end-face angles and require compatible mating ports. Avoid sharp bends and strain on the 3 mm cable; maintain the manufacturer recommended minimum bend radius for G.657.B3 fibre during installation and routing. When disconnecting, pull on the connector housing rather than the cable jacket to prevent damage.

Recommendations

Use the patchcord in indoor or FTTH environments where reduced smoke and halogen emissions are required. Store and route the cable avoiding tight kinks; for repeat connections keep connectors capped when not in use and periodically inspect end faces with a fibre scope to maintain low insertion loss and return loss.
