Network Cable Ekivalan LWL Duplex Patch Cable OS2 9/125 µm ST/ST yellow 1.0 m

The Ekivalan LWL Duplex Patch Cable OS2 9/125 µm with ST/ST connectors is a single-mode fiber optic patch cord designed for reliable high-speed data transmission in network infrastructures. The 9/125 µm core/cladding ratio indicates single-mode performance optimized for long-distance links and low attenuation. The cable is duplex, providing two fibers for bidirectional communication, and comes in yellow jacketing for straightforward identification in patch panels and cable trays. With a 1.0 m length, this patch cable is suitable for short interconnects between equipment in server rooms, racks, and distribution frames while maintaining signal integrity.

Advantages

The single-mode 9/125 µm fiber offers low insertion loss and tight optical performance tolerances suitable for high-bandwidth and long-reach applications. ST/ST connectors provide a bayonet-style coupling that ensures secure mating and easy handling during installation and maintenance. The duplex construction allows simultaneous transmit and receive channels in one compact cable, reducing clutter. Color-coded yellow jacket simplifies cable management and reduces the risk of mispatching in multi-fiber environments.

Suitable for

• Interconnections in data centers and server racks
• LAN/WAN backbone links and telecommunications rooms
• Fiber patch panels and optical distribution frames
• Point-to-point connections between network devices over short to moderate distances

Key specifications

• Fiber type: single-mode, 9/125 µm
• Connector type: ST on both ends (duplex)
• Jacket color: yellow for single-mode identification
• Length: 1.0 m
• Configuration: duplex patch cable (two-fiber)
• Typical applications: optical patching, equipment interconnects

How to use

Route the duplex patch cable between compatible ST connector ports on patch panels, transceivers or network devices. Align the bayonet-style ST connector with the mating adapter and push in, then twist to lock the coupling in place. Ensure connectors are clean before mating to avoid contamination-related signal loss; use a fiber cleaning tool or lint-free wipes with appropriate solvent if necessary. Avoid sharp bends and excessive pulling force; maintain the cable bend radius recommended for single-mode fiber to prevent microbending losses. Secure the cable in cable management trays or ties to prevent strain on the connectors.

Usage recommendations

Inspect and clean ST connectors before each connection, avoid tight bends and kinks, and store unused cables in protective loops. For critical links, verify optical loss with appropriate test equipment and replace any connector or segment that exceeds link budget allowances. Use the yellow jacket as part of a consistent color-coding scheme to simplify maintenance and troubleshooting.
