Ekivalan cavo patch in fibra ottica OM3 duplex ST/ST, 50/125 µm, aqua, 20 m COZOM3STST2SA0200A

The Ekivalan COZOM3STST2SA0200A is a 20-metre OM3 multimode duplex patch cable terminated with ST connectors on both ends. Its aqua jacket and 50/125 µm core/cladding dimensions provide a straightforward path for 10G Ethernet links up to 300 metres, making it a practical choice for short-range backbone or equipment connections where ST interfaces are still in service.

Highlights

• OM3 multimode fibre supports 10GbE up to 300 m, 40GbE and 100GbE up to 100 m
• Duplex ST/ST connectors with PC/UPC polish for low insertion loss
• Aqua LSZH jacket for easy identification and reduced smoke in fire conditions
• 20 m length suits structured cabling between patch panels and active equipment

In daily use

This cable is built for straightforward deployment in legacy ST environments. The duplex zip-cord design keeps transmit and receive fibres together, while the aqua colour immediately signals OM3 performance. The 50 µm core and 125 µm cladding are standard for multimode, and the PC/UPC polish on the ST connectors ensures a reliable physical contact with typical insertion loss under 0.3 dB.
