EFB R&M Duplex Patch Cable E2000/APC to E2000/APC OS2 Singlemode 3m LSZH 3mm Yellow G657A1 Grade C

For fibre optic links that demand low loss and high return loss, this EFB R&M duplex patch cable pairs E2000/APC connectors on both ends with bend-insensitive G.657.A1 singlemode fibre. The 3-metre length and 3 mm LSZH jacket make it a practical choice for patching in data centres, FTTx cabinets, or telecom rooms where space is tight and safety regulations apply. Unlike standard patch leads, the E2000/APC interface includes an integrated spring-loaded shutter that protects the ferrule from dust and laser radiation whenever the connector is unmated.

Highlights

• Duplex OS2 singlemode fibre with 9/125 µm core/cladding for long-reach, high-speed transmission.
• E2000/APC connectors on both ends: 8° angled polish minimises back reflection, typically ≥60 dB return loss.
• Bend-insensitive G.657.A1 fibre allows tight routing with a minimum bend radius of 10 mm.
• LSZH (Low Smoke Zero Halogen) yellow jacket, 3 mm diameter, for safe indoor use in public buildings.
• Grade C quality with zirconia ceramic ferrules for consistent insertion loss ≤0.25 dB.
• Compliant with RoHS and REACH; suitable for 10G, 40G, and 100G Ethernet, Fibre Channel, and other protocols.

In daily use

Installation is straightforward: the E2000/APC connectors click into compatible adapters and the push-pull locking mechanism prevents accidental disconnection. The duplex zip-cord design keeps transmit and receive fibres together, simplifying cable management. The yellow LSZH jacket is easy to identify among copper cables and does not emit toxic fumes in the event of fire. Whether you are patching between switches and patch panels, connecting optical distribution frames, or extending a fibre link in a server rack, this cable provides reliable performance with low insertion loss and high return loss, ensuring signal integrity for today's high-bandwidth applications.
