Fiber optic duplex SM patch cord, OEM PCLCSC9D2-2L, 2 m length, 2 mm diameter

Duplex single-mode (SM) fiber optic patch cord OEM PCLCSC9D2-2L is a two-fiber cable designed for point-to-point optical connections. It has a 2 m length and a 2 mm outer jacket diameter, providing a compact and flexible link for networking equipment, optical transceivers and patch panels. The cord supports low-loss single-mode transmission for data, telecom and fiber infrastructure projects where stable optical performance and predictable insertion loss are required.

Advantages

The duplex SM patch cord offers consistent single-mode propagation with low attenuation and stable mechanical performance. Its 2 mm jacket balances flexibility and protection for routing in cabinets and inside racks. Constructed for optical patching environments, the cable facilitates straightforward installation and reliable optical performance across short to medium link distances. The duplex configuration keeps transmit and receive channels paired for simplified polarity management.

Suitable for

• Connecting optical transceivers in switches, routers and SFP ports
• Patch panel interconnections in data centers and telecom rooms
• Point-to-point links between active networking equipment
• Laboratory and testing setups requiring predictable single-mode links

Key specifications

• Fiber type: single-mode (SM), duplex
• Length: 2 meters
• Outer jacket diameter: 2 mm
• Connector arrangement: duplex (paired transmit/receive)
• Typical use: patching and short-range single-mode links

How to use

Route the duplex fiber patch cord between desired optical ports, ensuring connectors are clean before insertion. Align the paired connectors with the corresponding transmit and receive ports on transceivers or patch panels to maintain correct polarity. Avoid tight bends and secure the cable with appropriate cable management to prevent stress on connectors and the fiber. When disconnecting, pull on the connector body rather than the cable jacket to reduce strain.

Usage recommendations

Inspect and clean connector endfaces with appropriate fiber cleaning tools before each use, follow bend radius limits for the 2 mm jacket to prevent excess loss, and store unused cords coiled without sharp kinks. For critical links, verify insertion loss and return loss with suitable test equipment after installation.
