RamboCables OS2 SC-LC Singlemode Duplex Patch Cables

RamboCables OS2 SC-to-LC single-mode duplex patch cords (26ft/8m, 4-pack) are high-performance fiber cables built for reliable 10G+ network links with LSZH jackets and precision SC/UPC to LC/UPC connectors.

These singlemode fiber patch cables from RamboCables pair OS2 graded 9/125μm fiber with SC to LC connectors to deliver low-loss, long-reach links suitable for data centers, telecom racks, and enterprise backbone connections. Designed for high-density installations, the 2.0mm OD duplex cable uses low-smoke zero-halogen (LSZH) jacket material and zirconia ferrules for repeatable connections and improved safety in enclosed spaces.

How far can these OS2 single-mode cables transmit data reliably?

OS2 single-mode fiber is optimized for long-distance transmission. At 1310nm the cable supports spans up to about 10 km, while at 1550nm it can extend to tens of kilometers depending on network losses and transceiver performance.

• Maximum recommended distance: ~10 km at 1310nm, longer at 1550nm
• Insertion loss typical values per connector kept low by zirconia ferrules
• Bandwidth figures: low attenuation (≈0.36 dB/km at 1310nm; ≈0.22 dB/km at 1550nm)
• Works with 1G/10G/40G/100G optics and many singlemode transceivers

What connectors and construction features ensure stable performance?

These patch cords use SC/UPC connectors on one end and LC/UPC on the other, both with ceramic (zirconia) ferrules for precise alignment. The duplex format and industry-standard polishing and inspection help maintain low reflectance and consistent insertion loss across multiple mating cycles.

• SC/UPC to LC/UPC connector pairing for common transceiver types
• Zirconia ceramic ferrules for repeatable low-loss connections
• Factory-tested to industry optical standards with quality inspection
• 15 mm minimum bend radius for tighter routing in racks and enclosures

Is the cable suitable for datacenter and indoor installation safety requirements?

The cable jacket is LSZH (low-smoke zero-halogen), reducing toxic fumes and corrosive gases in the event of fire—important for confined spaces and plenum-adjacent installations. The 2.0mm diameter duplex design balances flexibility with durability for organized, high-density cabling runs.

• LSZH jacket minimizes smoke and hazardous gas emissions
• 2.0mm OD duplex cable for compact routing and less clutter
• Operates across typical telecom temperatures (-20°C to 70°C)
• Supports high-density panels, blade servers, and transceiver modules

How do I choose the right length and use these cables in my setup?

Measure the physical path between equipment with routing slack for moves and management; RamboCables offers lengths from 1m to 10m and the shown 8m option. Choose duplex routing where both transmit and receive fibers are needed; color-coded connectors or cuffs help keep polarity correct during installation.

• Available length options: 1 m through 10 m (this listing: 26ft/8m, 4-pack)
• Use duplex connections for bidirectional singlemode transceivers
• Allow service loop slack for maintenance and re-termination
• Label both ends to preserve link polarity and simplify troubleshooting

Who is this for: Network engineers, data center technicians, and IT managers who need dependable single-mode patching for 10G or higher links will find these RamboCables OS2 SC-LC duplex cords useful. They suit high-density racks, carrier networks, storage arrays, and any indoor environment that demands low attenuation, compact cabling, and LSZH safety compliance.
