Ekivalan OS2 duplex patchkábel SC APC–SC PC 50 m sárga COZ008DADC2SJ0500A

Long-distance fibre links often suffer from weak return loss and unstable connections when the wrong polish types are paired. This 50-metre OS2 single-mode duplex patch cable solves that by combining an SC APC connector on one end with an SC PC connector on the other, delivering low insertion loss and high return loss for reliable signal integrity in data centres, telecom rooms, and FTTH installations.

Who is it for

Network engineers and installers who need a ready-to-use, 50-metre single-mode fibre jumper with mixed APC/PC polish. It is ideal for patching between equipment that requires different connector polishes, such as from an OLT with APC to a switch with PC, or for test and measurement setups.

Main features

• OS2 single-mode fibre, 9/125 µm core/cladding, supports long-distance transmission.
• Duplex construction with two fibres in one cable for bidirectional communication.
• SC APC to SC PC connectors: angled polish on one end, flat polish on the other.
• Yellow LSZH jacket: low smoke, zero halogen, safe for indoor use.
• Ceramic ferrules ensure precise alignment and durability.
• Maximum insertion loss ≤ 0.3 dB; return loss ≥ 60 dB (APC) and ≥ 50 dB (PC).
• Operating temperature range: -20°C to 70°C.

Tips

When connecting SC APC to SC PC, ensure the mating adapters match the polish type to avoid damaging the ferrule endfaces. Always clean connectors before installation to maintain low insertion loss.
