Aqua blue duplex fibre patch cable with SC and ST connectors, 3.0 mm jacket, 20 m length

Enfain

Enfain OM3 SC-ST Duplex Multimode Fibre Optic Cable 20m

SKU CH-TPDT-HFV4N

A 20 m OM3 duplex multimode patch cord with SC and ST ceramic ferrules, 3.0 mm PVC jacket, 850 nm wavelength, .2 dB typical insertion loss and >38 dB return loss

Length 20m

  • OM3 core supports 10 Gb links over 20 m
  • Low 0.2 dB typical insertion loss keeps signal strong
  • Return loss above 38 dB reduces reflection errors
  • 0 mm PVC jacket with 330 mm bend radius eases routing
  • Rated for 1000 mating cycles from -20 °C to 60 °C

Enfain OM3 SC-ST Duplex 20m Cable

This OM3 multimode duplex patch cord uses SC and ST connectors for 10-gigabit links across a 20-metre run. It suits data-centre, server-room and switch-to-switch connections where OM3 850nm transmission is specified. Builders needing single-mode reach or different connector pairs should select another cable.

Thermals Noise and Power Draw

As a passive fibre assembly the cable generates no heat, draws no power and produces no audible noise in normal use. The 3.0-millimetre PVC jacket operates reliably from minus 20°C to plus 60°C, so rack airflow and cooling requirements stay unchanged.

Accessories and Software Impact

The cord ships with ceramic ferrules and is rated for 1000 insertion cycles with typical insertion loss of 0.2dB and maximum of 0.3dB. Return loss exceeds 38dB and the minimum bend radius is 330mm. No software, drivers or active components are included or required.

Soalan tentang produk ini

How do I connect the SC and ST ends to my switch and server, and what is the common mistake?

Insert the SC connector into the switch port and the ST connector into the server NIC until each clicks; the common mistake is not pushing far enough to lock the ferrule, which leaves a gap that raises insertion loss above the typical 0.2 dB.

What cleaning or replacement schedule should I plan for the ceramic ferrules?

Inspect the end faces before every reconnect; clean with a lint-free wipe and isopropyl alcohol if contaminated, and budget for replacement after roughly 1000 mating cycles when return loss may drop below 38 dB.

At what bend radius does signal loss spike during a long cable run?

Keep every bend radius at or above 330 mm; tighter bends increase attenuation at the 850 nm wavelength and can push insertion loss past the 0.3 dB maximum spec.
