Fibre optic cable BlueOptics SFP3333BU7.5MK 7.5 m ST Yellow

The BlueOptics SFP3333BU7.5MK 7.5 m ST Yellow fibre optic cable is a single-length patch cable designed for reliable optical connections in data communication environments. It uses G.657.A1 bend-insensitive fibre with a 125 µm core diameter to maintain signal integrity over its 7.5 meter length and features ST connectors at each end for simple push-and-twist coupling. The cable's yellow jacket and blue product designation make it easy to identify in structured cabling installations.

Advantages

The G.657.A1 fibre type reduces sensitivity to tight bends and routing constraints, helping to preserve optical performance in confined pathways. A 125 µm core diameter provides standard compatibility with common single-mode equipment, and the 7.5 m length offers flexibility for connecting devices across short to medium distances in racks, cabinets, or office environments. ST connectors provide a durable mechanical coupling and are compatible with legacy equipment that accepts bayonet-style fibre terminations.

Suitable for

• Connecting single-mode transceivers, switches, and media converters in local networks
• Patching between distribution panels and active network equipment within server rooms or wiring closets
• Temporary or permanent links in campus, industrial, or office cabling where bend-insensitive fibre is required

Key specifications

• Fibre type: G.657.A1 (bend-insensitive single-mode)
• Length: 7.5 m
• Connector type: ST to ST (bayonet-style)
• Core/cladding diameter: 125 µm
• Jacket colour: Yellow
• Intended use: Single-mode optical patching

How to use

Inspect connector endfaces for cleanliness before installation and, if necessary, clean using appropriate fibre-optic cleaning tools. Align the ST connector with the device's receptacle and insert, then twist the bayonet sleeve until it locks to ensure a secure mechanical connection. Route the cable avoiding sharp bends and excessive tension; the G.657.A1 fibre tolerates tighter bends but standard bend-radius best practices should still be followed. When disconnecting, twist the bayonet sleeve to release before pulling out the connector.

Usage recommendations

Store and handle the cable in a clean environment to prevent contamination of connector endfaces. Use dust caps when connectors are not in use and avoid kinking the cable. For long-term installations, label both ends to simplify maintenance and troubleshooting.
