RamboCables OS2 LC‑LC Single‑Mode Fiber Patch Cable 165ft

RamboCables 165ft (50m) OS2 LC-to-LC single-mode duplex patch cable provides reliable, low-loss fiber connectivity for 1G–400G networks with an LSZH jacket and 2.0mm diameter.

This single-mode LC–LC patch cord from RamboCables is built for data centers, server rooms, and high-speed network links where long reach and low attenuation matter. The OS2 9/125μm fiber supports industry-standard wavelengths (1310/1550nm), features LC/UPC connectors with zirconia ferrules, and uses an LSZH jacket for safer installations in enclosed spaces. Available in many lengths (0.2m–305m) and sold in convenient multi-packs, it balances performance with value for large deployments.

How does this cable perform over long distances?

The OS2 single-mode construction is optimized for long-haul and campus backbone links. Expect very low attenuation across standard telecom windows, enabling transmission to kilometers without signal degradation when paired with compatible transceivers.

• Supports up to ~10 km at 1310nm and up to ~40 km at 1550nm under typical link budgets
• Attenuation approximately 0.36 dB/km at 1310nm and 0.22 dB/km at 1550nm
• 9/125μm core/cladding for single-mode compatibility with modern optics
• 15 mm minimum bend radius preserves performance in routed paths

Which devices and networks is this LC–LC duplex cable compatible with?

Designed to plug directly into LC-equipped transceivers and ports, the RamboCables LC–LC patch cord supports a wide range of Ethernet speeds and fiber modules. It works with SFP+, QSFP+, and other 10G–400G capable optics when the link budget and transceiver type match.

• Compatible with 1G/10G/40G/100G/400G network equipment and common transceivers
• Fits LC/UPC to LC/UPC duplex ports on switches, servers, and patch panels
• Suitable for QSFP+, SFP+, and BIDI modules when paired correctly
• Available in many lengths to tailor runs and minimize splicing or adapters

What safety and build-quality features are included?

This cable uses industry-standard materials and construction to meet installation and safety requirements. The LSZH jacket reduces smoke and toxic gas if exposed to fire and the 2.0mm jacket diameter gives a balance of flexibility and durability for cable management.

• LSZH (Low Smoke Zero Halogen) outer jacket for safer indoor installations
• Zirconia ceramic ferrules for consistent low insertion and return loss
• 2.0mm outer diameter for flexible routing in trays and conduits
• Meets EIA/TIA 604-2 alignment and performance conventions

How should I choose the right length and quantity?

Measure run distances including slack for patch panels and service loops, then select the next standard length to avoid tension. Buying multi-packs is cost-effective for deployments that require many identical runs.

• Available lengths from 0.2m to 305m to match patching and backbone needs
• 10-pack option reduces per-cable cost for rack and row installations
• Include service loops and connector clearance in your measurement
• Check transceiver type and link budget before finalizing length choices

Who is this for: Network engineers, data center operators, and IT teams who need reliable single-mode duplex fiber for backbone links, long-distance connections, or high-density patching. RamboCables' OS2 LC–LC cords are a practical option for large-scale rollouts, cloud infrastructure, and enterprise networks that demand low loss, safe indoor jacketing, and consistent connector quality without premium pricing.
