Optical patch cable SC-SC duplex singlemode 3 m

Singlemode optical patch cable SC-SC duplex 3 m is a fiber patch cord designed for interconnecting equipment in telecom environments, data centers and network racks. The cable features duplex SC connectors on both ends and a 3 meter length that provides a balance between reach and cable management. It is intended for singlemode links where low insertion loss and stable optical performance are required for connecting transceivers, patch panels and active network devices.

Advantages

The SC-SC duplex design offers simple, push-pull mating and polarization stability for duplex singlemode links. With a 3 m cable length, the cord reduces the need for intermediate splices while keeping routing flexible within racks or cabinets. The singlemode fiber core minimizes attenuation over distance and supports long-reach signaling. The connectors are designed for repeatable low-loss connections and are compatible with standard SC ports used in most telecom and networking equipment.

Suitable for

• Connecting singlemode SFP/SFP+ transceivers to patch panels or switches
• Interlinking optical distribution frames and rack-mounted equipment
• Fiber backbone links inside data centers and telecom closets
• Replacing or extending existing SC duplex connections in network cabinets

Key specifications

• Fiber type: Singlemode (ITU-T G.652 compliant typical)
• Connector type: SC duplex on both ends
• Mode: Singlemode (SM)
• Length: 3 meters
• Polish type: PC or UPC typical for low back-reflection (depends on factory configuration)
• Jacket: Flexible outer jacket suitable for indoor rack and cabinet use
• Typical insertion loss: low (factory-terminated, measured per connector)

How to use

Route the SC-SC duplex singlemode cable through the rack or conduit following existing cable management paths to avoid sharp bends and stress on the fiber. Align and insert each SC connector into the corresponding SC port until it clicks; ensure transmit and receive channels are correctly paired. Verify optical link integrity using an optical power meter or diagnostic LEDs on equipment. When disconnecting, pull the connector body straight out to avoid damaging the ferrule or the adapter.

Usage recommendations

For reliable performance, maintain minimum bend radii as specified for singlemode fiber, keep dust caps on connectors until installation, and perform visual inspection or end-face cleaning when optical loss or reflections are higher than expected.
