HELOS E2000 APC to E2000 APC Duplex OS2 Single-Mode Fiber Patch Cable, 9/125µm, LSZH, Yellow, 1m

For network engineers who refuse to compromise on signal integrity, this HELOS duplex OS2 patch cable pairs E2000 APC connectors on both ends with a precision 9/125µm single-mode core, delivering return loss of at least 60 dB and insertion loss under 0.3 dB at every mating. The angled physical contact polish virtually eliminates back reflections, making it the dependable link for high-speed backbone runs, FTTx distribution, and dense patching fields where clean light transfer is non-negotiable.

Highlights

• Duplex E2000 APC to E2000 APC connectors with spring-loaded shutters for dust and laser protection
• OS2 single-mode fibre, 9/125µm core/cladding, optimised for 1310 nm and 1550 nm wavelengths
• Low insertion loss (≤ 0.3 dB) and high return loss (≥ 60 dB) ensure stable, error-free transmission
• LSZH (Low Smoke Zero Halogen) yellow jacket reduces toxic smoke in fire conditions, ideal for enclosed spaces
• 1-metre length with duplex zip-cord construction for easy routing and identification

In daily use

Install this cable in data centres, campus backbones, or telecom rooms and you will notice the difference immediately: no intermittent link drops, no CRC errors creeping into your logs. The E2000 APC connectors click securely into adapters and panels, while their integrated covers keep the ferrule end-faces clean when unplugged. The yellow LSZH jacket stands out against dark cable trays, simplifying tracing during moves and changes. Because it is built to OS2 standards, it supports current and future high-speed protocols over long distances without the need for replacement.
