RamboCables 15m OS2 LC‑LC Single‑Mode Fiber Patch 5‑Pack

RamboCables 15m OS2 LC-to-LC single‑mode fiber patch cables are a 5‑pack of LSZH duplex 9/125μm cords built for reliable 10G+ networking and long‑reach single‑mode links.

These LC‑to‑LC OS2 patch cords (15 meters each, sold as a 5‑pack) are designed for modern data centers, server rooms, telecom closets and lab racks that require consistent low loss and standardized connectivity. With a 2.0mm LSZH jacket, zirconia ferrules and 9/125μm single‑mode fiber, they support a wide range of transceivers and Ethernet speeds while meeting industry EIA/TIA standards for insertion and return loss.

How do these cables perform for 10G and higher networks?

The OS2 single‑mode construction offers low attenuation and high bandwidth suitable for 1G through 400G applications when paired with appropriate optics. Expect stable transmission up to several kilometers depending on wavelength and transceiver type, making these cords suitable for both short links in racks and longer inter‑rack connections.

• Supports 1G/10G/40G/100G/400G with compatible transceivers
• Low attenuation: ~0.36–0.22 dB/km across 1310–1550 nm
• Works with SFP+/QSFP+ and BIDI modules for diverse setups

What build quality and standards do these patch cords meet?

Each cable uses a 9/125μm OS2 fiber core, LC/UPC connectors with zirconia ceramic ferrules and an LSZH outer jacket to reduce smoke and toxic gas if exposed to fire. The 2.0mm duplex jacket and minimum 15mm bend radius protect fiber performance in tight routing and high‑density panels.

• LSZH jacket for safer indoor installations and code compliance
• Zirconia ferrules and LC/UPC polishing for reliable IL/RL
• Conforms to EIA/TIA 604‑2 connector standards

How far can data travel over these OS2 fibers?

Transmission distance depends on wavelength and network equipment. OS2 single‑mode fiber is optimized for longer links—several kilometers at 1310 nm and much farther at 1550 nm—so it handles both short rack runs and extended campus links when paired with appropriate optics.

• Up to ~10 km at 1310 nm with standard transceivers
• Extended reach (tens of kilometers) possible at 1550 nm
• Temperature range −20°C to 70°C for stable outdoor/indoor environments

Why choose a 5‑pack of 15m cables instead of single cables?

Buying a 5‑pack is cost‑efficient for outfitting multiple ports, stocking spares, or building mirrored links. It streamlines deployment by providing identical length and performance across connections, reducing troubleshooting and ensuring consistent loss characteristics across paired links.

• Bulk packaging lowers per‑cable cost and simplifies procurement
• Identical length and specs reduce mismatch during installs
• Convenient for staging racks, data closets, and redundant paths

Who is this for: Network engineers, IT managers, data center technicians and systems integrators who need dependable single‑mode LC‑to‑LC patch cords in standardized lengths. These RamboCables 15m OS2 duplex cords are best when you want LSZH safety, predictable optical performance, and a cost‑effective multi‑pack for multi‑port deployments or spare inventory.
