RamboCables 40m OS2 LC-LC Single-Mode Fiber Patch Cable

RamboCables 40m OS2 LC-LC is a single-mode duplex fiber patch cable designed for high-speed, long-reach network links with LSZH jacket and LC/UPC connectors.

This 40-meter (130 ft) OS2 LC-to-LC single-mode duplex patch cord from RamboCables combines 9/125μm fiber with a slim 2.0mm LSZH jacket to deliver reliable 10G and above connectivity for data centers, enterprise racks, and telecommunications cabinets. Built to EIA/TIA standards with zirconia ferrules and LC/UPC connectors, it balances low loss, compact routing, and environmental safety for indoor installations.

How does this cable support high-speed networking?

The OS2 single-mode fiber is optimized for long-wavelength transmission, enabling 10G+ performance and compatibility with modern transceivers. Low attenuation and precise connectors keep insertion loss and return loss within industry expectations so links remain stable under load.

• Supports 1G/10G/40G/100G/400G applications and common transceivers (SFP+, QSFP+, etc.).
• Optimized for 1310nm and 1550nm wavelengths with low attenuation (≈0.36–0.22 dB/km).
• LC/UPC to LC/UPC connectors with zirconia ceramic ferrules for consistent coupling.
• Duplex configuration for full-duplex optical links.

What are the physical and environmental specs I should know?

This 40m cable uses 9/125μm single-mode fiber inside a 2.0mm diameter jacket that’s LSZH-rated for reduced smoke and no halogen in the event of fire. It is built with a minimum bend radius to support tight routing while maintaining optical performance across a wide temperature range.

• Cable diameter: 2.0mm; minimum bend radius: 15mm.
• Operating temperature range: -20°C to 70°C for indoor deployments.
• LSZH jacket meets low-smoke, low-toxicity safety requirements for enclosed spaces.
• Conforms to EIA/TIA 604-2 connector standards for mechanical fit and performance.

How far can this OS2 single-mode cable transmit data reliably?

OS2 single-mode fiber enables long-distance links with minimal signal loss when used with appropriate optics. Expect reliable single-span transmission up to several kilometers depending on wavelength and transceiver power budgets.

• Typical reach: up to 10 km at 1310nm and up to 40 km at 1550nm in single-mode environments.
• Low attenuation supports extended links without intermediate amplification for many installations.
• Works with 10G SR, 40G BIDI SR, and other commonly deployed optics when specified.

What packaging and purchasing options are available?

RamboCables offers bulk-friendly packaging and multi-pack options to simplify installations and reduce cost per cable. Buying in packs is convenient for rack deployments and multi-run projects.

• Available in quantities from single units up to bulk lengths (7 inch to 1000 ft options for other SKUs).
• 10-pack options provide cost savings and consistent labeling for data center installs.
• Each cord ships with factory-terminated LC/UPC connectors and quality control testing.

Who is this for? Network engineers, data center technicians, and IT teams who require reliable, standards-compliant single-mode duplex patch cords for 10G and higher links will find the RamboCables 40m OS2 LC-LC cable a practical choice. It suits rack-to-rack connections, fiber patch panels, and long-reach interconnects where low loss, LSZH safety, and tight routing are priorities.
