Fibre optic cable EFB Elektronik O2003.15 15 m 2x ST I-V(ZN) H Yellow

The EFB Elektronik O2003.15 is a 15 m fibre optic cable with two ST connectors and OS2 single-mode fibre (core diameter 9 µm). Designed for long-distance, low-loss transmission, the cable uses an I-V(ZN) H construction with a bright yellow outer jacket for visibility and protection. It is intended for indoor cabling runs, patching between equipment, or linking network segments where single-mode performance is required.

Advantages

The cable provides stable, low-attenuation signal transfer thanks to the OS2 single-mode fibre and 9 µm core diameter. Dual ST connectors offer straightforward push-and-twist connections compatible with many legacy and industrial networking devices. The I-V(ZN) H design balances mechanical protection and flexibility for routing in trays, conduits, or along walls. The yellow jacket improves visibility during installation and reduces the chance of accidental damage.

Suitable for

• Connecting single-mode transceivers, media converters, and optical patch panels
• Indoor backbone or horizontal runs in offices and server rooms
• Testing, temporary links, and field installations requiring visible cabling

Key specifications

• Cable length: 15 m
• Connector type: 2 × ST (push‑and‑twist)
• Fibre type: OS2 single-mode
• Core diameter: 9 µm
• Construction: I-V(ZN) H
• Outer jacket colour: yellow

How to use

Route the cable along the planned path, avoiding tight bends and sharp edges that could damage the fibre. Clean connector endfaces before mating to reduce insertion loss and reflections. Insert each ST connector into the corresponding adapter or device port and twist to lock. Verify link status and measure optical power or attenuation if required to confirm proper installation. Coil excess cable with gentle loops to prevent stress on the fibre.

Recommendations

Store and handle the cable within recommended bend radius limits and protect connectors with dust caps when not in use. For permanent installations, use appropriate cable management and strain relief; for testing or temporary setups, keep the cable visible to reduce trip hazards and accidental disconnection.
