Fibre optic cable EFB Elektronik O0361.7,5

The EFB Elektronik O0361.7,5 is a 7.5 m single-mode OS2 fibre optic cable with LC and ST connectors, designed for point-to-point and patching applications in structured cabling. With a 9 µm core diameter and full duplex configuration, the cable supports high-speed, low-loss optical transmission over longer distances than multimode alternatives. Its connector pairing (LC on one end and ST on the other) provides compatibility with a wide range of networking devices and patch panels used in telecom, datacenter and industrial environments.

Advantages

The cable offers single-mode OS2 performance, which reduces attenuation and maintains signal integrity across extended runs. Its 9 µm core is optimized for single-mode lasers and transceivers, enabling stable high-bandwidth links. The LC and ST connectors combine a compact, latch-style interface with a bayonet-style connector for legacy equipment, increasing interoperability. The 7.5 m length suits both rack-to-rack and equipment-to-equipment connections while minimizing excess slack.

Suitable for

• Point-to-point connections between switches, routers and media converters
• Patching between distribution frames, patch panels and active equipment
• Telecommunications and single-mode backbone links
• Data centers and network rooms requiring low-attenuation fibre links
• Environments where mixed connector types (LC and ST) are needed

Key specifications

• Fiber type: Single-mode OS2
• Length: 7.5 m
• Core diameter: 9 µm
• Configuration: Full duplex (duplex fiber pair)
• Connectors: LC (one end) and ST (other end)
• Typical application: Patch cable / patchcord for optical networks

How to use

Connect the LC-terminated end to the LC port on the device or patch panel and insert the ST-terminated end into the corresponding ST socket. Ensure connectors are clean before mating to prevent insertion loss; use appropriate fiber-cleaning tools or lint-free swabs with isopropyl alcohol. Route the cable following bend-radius recommendations for single-mode fibre and secure it with cable management to avoid strain. For duplex operation, keep both fiber strands paired and aligned to the transmit and receive ports as required by the devices.

Recommendations

Inspect and clean connectors prior to installation, avoid tight bends (maintain recommended minimum bend radius), and use labelled cable management for easy identification. Verify link performance after installation with an optical power meter or appropriate testing equipment to ensure low insertion loss and correct polarity.
