Fiber patch cord LANBERG SM LC/APC–LC/UPC duplex 3.0 mm LSZH G.657.A1 0.5 m yellow

LANBERG singlemode fiber patch cord, duplex LC/APC to LC/UPC, 0.5 m long with a 3.0 mm LSZH jacket and G.657.A1 bend-insensitive fiber. This patch cord provides low insertion loss and reliable singlemode connections for telecom, data center and networking equipment. The duplex LC connector pair combines an angled-polished LC/APC on one end and a UPC-polished LC on the other end to support networks that require stable return loss performance and simple duplex fiber routing in confined spaces.

Advantages

The LSZH outer jacket reduces smoke and toxic gas emission in case of fire while maintaining flexibility for tight routing. G.657.A1 fiber offers improved bend performance to minimize signal degradation in densely cabled environments and sharp bends. The 3.0 mm diameter cable balances durability and manageability, and short 0.5 m length is suitable for patch-panel to transceiver connections or for linking adjacent equipment in racks and enclosures.

Suitable for

• Patch panels and fiber distribution frames in data centers
• Direct links between transceivers and optical equipment in telecom racks
• Short-distance interconnects inside networking cabinets and enclosures

Key specifications

• Fiber type: singlemode, G.657.A1 bend-insensitive
• Connector configuration: duplex LC/APC to LC/UPC
• Cable diameter: 3.0 mm
• Jacket material: LSZH (Low Smoke Zero Halogen)
• Length: 0.5 m
• Polish: one end APC angled polish, other end UPC ultra-polish

How to use

Route the patch cord along existing cable management paths avoiding sharp kinks; the G.657.A1 fiber tolerates tighter bends but abrupt creasing should be avoided. Insert the LC connectors into the appropriate duplex adapters or transceiver ports until they click into place, ensuring correct polarity for transmit and receive channels. For removal, press the LC latch and pull straight out to avoid stressing the connector ferrule or fiber. Keep protective dust caps on unused connectors to maintain low loss and prevent contamination.

Usage recommendations

For reliable performance, use this 0.5 m LANBERG patch cord for short patching runs and transceiver connections inside racks or on patch panels. Periodically inspect connector endfaces and clean with approved fiber cleaning tools if contamination is suspected. Avoid repeated tight bending and secure the cable with cable ties or Velcro straps without over-compressing the jacket.
