1/2/3/5/7/10m LC/UPC-SC/UPC Duplex Single-Mode OS2 Fiber Optic Patch Cord

Standard 50/125μm & 62.5/125μm fiber core specifications fit various indoor optical wiring, providing versatile customized termination solutions for FTTX and structured cabling projects.

Key specifications

Core diameter:

Typically 9/125μm (9μm core, 125μm cladding).

Operating wavelength:

Supports 1310nm and 1550nm, as well as a wider wavelength range (1260–1625nm).

Attenuation:

Maximum attenuation at 1310nm and 1550nm is only 0.4dB/km, significantly lower than the 1.0dB/km of OS1.

Transmission distance:

Supports 10km transmission at 10Gbps, 1km at 40G/100G, or up to 200km.

Standards:

Complies with ITU-T G.652.C/D standards; eliminates the "water peak" and supports full-spectrum transmission.

Differences from OS1 single-mode fiber

OS2 is an upgrade to OS1. OS1 features a tight-buffered structure and is primarily suitable for indoor use (up to 10 km), whereas OS2 typically employs a loose-tube design, making it better suited for harsh outdoor environments; furthermore, its extremely low attenuation enables transmission over longer distances and at higher bandwidths (40G/100G).

Key Application Scenarios

Telecommunications networks:

Metropolitan Area Networks (MANs), Wide Area Networks (WANs), and long-haul backbone networks.

High-speed data centers:

Connecting 40G/100G/400G core switches.

Outdoor cabling:

Suitable for backhaul networks in outdoor or extreme environments, as the loose-tube structure provides superior mechanical protection.

Common Specifications and Performance

Taking the LC-LC duplex single-mode OS2 patch cord—commonly found on the market—as an example:

Connectors:

Typically feature high-precision ceramic ferrules; typical insertion loss is ≤0.30 dB.

Return Loss:

≥60 dB for APC polish; ≥50 dB for UPC polish.

Outer Jacket:

Available in materials such as PVC and LSZH (Low Smoke Zero Halogen); some versions offer UV resistance.
