Ekivalan OS2 duplex kuitu-patch-kaapeli ST/ST 9/125 µm keltainen 0,5 m COZ008STST2SJ0005A

In a data centre rack or a telecom distribution frame, this 0.5 m OS2 single-mode duplex patch cable links ST-terminated equipment with a reliable yellow PVC jacket that stands out for easy identification. The 9/125 µm core/cladding geometry and ultra bend-insensitive fibre support stable 1310 nm and 1550 nm transmission, while ceramic ferrules on both ST connectors ensure precise alignment and low insertion loss.

Key specifications

• Cable length: 0.5 m
• Fibre type: OS2 single-mode, 9/125 µm
• Connectors: ST to ST, duplex
• Insertion loss: ≤ 0.3 dB
• Return loss: ≥ 50 dB
• Jacket material: PVC, yellow
• Attenuation: ≤ 0.35 dB/km at 1310 nm, ≤ 0.25 dB/km at 1550 nm

Why choose it

The OS2 fibre is ultra bend-insensitive, reducing the risk of signal degradation in tight cable management spaces. Ceramic ferrules provide consistent mating and long-term durability, and the duplex ST connectors are a proven choice for legacy and industrial fibre installations.

Ideal use cases

• Connecting ST-equipped switches, media converters, or patch panels in data centres
• Telecommunications backbone links requiring single-mode performance
• FTTx and LAN segments where ST connectors are specified

Good to know

The yellow jacket follows the conventional colour code for single-mode fibre, simplifying identification in mixed-fibre environments. The cable's 3.0 mm diameter balances flexibility with robustness for structured cabling.
