CBO Duplex LWL Patch Cable Singlemode 3 m SFP9131BU3MK

CBO Duplex LWL Patch Cable Singlemode 3 m SFP9131BU3MK is a singlemode fiber optic duplex patch cable designed for optical connections in telecommunications and data centre environments. With a 3-meter length and standardized duplex connectors, this BlueOptics cable provides two-fiber transmission for transmit and receive channels. The product is intended for linking SFP/SFP+ transceivers, switches, routers and other optical network equipment where low-loss, singlemode connections are required.

Advantages

The cable offers singlemode transmission to support long-distance, low-attenuation links and standardized duplex connectors for straightforward mating with SFP and SFP+ modules. A durable outer jacket protects the fibers against mechanical stress and frequent handling while maintaining consistent optical performance. The 3 m length balances reach and cable management for rack and cabinet installations.

Suitable for (tasks / use cases)

• Connecting SFP and SFP+ optical transceivers in network equipment
• Interlinking switches, routers and media converters in data centres
• Patch panel to active equipment connections in telecom racks
• Low-loss singlemode point-to-point fiber runs within structured cabling

Key specifications

• Fiber type: singlemode (duplex)
• Length: 3 m
• Connector type: duplex connectors compatible with SFP/SFP+ transceivers
• Transmission: two-fiber (separate transmit and receive channels)
• Jacket: durable outer sheath for protection and handling

How to use

Route the cable between the two devices ensuring gentle bends and avoiding sharp kinks. Insert each connector into the corresponding SFP/SFP+ module or panel port until it latches or seats fully according to the equipment’s connector orientation. Confirm transmit and receive channels are correctly aligned and secure the cable with appropriate cable management to prevent stress on the connectors and fiber. If necessary, test link status and optical power using the network equipment or optical test tools to verify low-loss operation.

Usage recommendations

For reliable performance, avoid bending the cable below the manufacturer’s minimum bend radius, protect connectors from dust when not in use, and route the cable to minimize tension and mechanical stress. Use compatible SFP/SFP+ modules and verify port duplex orientation before final installation.
