Overview

ST/UPC-ST/UPC SM SX OS2 9/125µm Patch Cord is a high-performance single-mode fiber optic cable designed for reliable, high-speed data transmission in demanding networking environments. Featuring ST/UPC connectors with ultra-polished ceramic ferrules, it ensures low insertion loss (<0.3 dB) and high return loss (>55 dB), optimizing signal integrity over long distances. The 9/125µm OS2-compliant single-mode fiber supports applications requiring high bandwidth and low attenuation, including telecom networks, data centers, and CATV systems.

Built with a durable LSZH (Low Smoke Zero Halogen) jacket, this patch cord offers flame-retardant properties and resistance to environmental stressors, making it suitable for both indoor and outdoor installations. Its ruggedized design and precise connector alignment guarantee stable connections in high-density setups. Ideal for 10G/40G/100G networks, this patch cord complies with industry standards (IEC, TIA/EIA), delivering exceptional performance for mission-critical optical infrastructure.

velolan supply various kinds of Single Mode and Multimode Fiber Optic Loopback Cables, which are with different connectors including ST, SC, FC, LC, MU, MTRJ etc. Each cable is functionally tested before shipping and is covered by a lifetime warranty.

How to choose correctly the cable jacket: PVC, LSZH or OFNP?

Fiber patch cables are now widely used for indoor applications like buildings, factories, office parks, campuses and so on. Whether you choose PVC, LSZH or OFNP jacket depends on where you're going to run the cable.
The features of PVC, LSZH and OFNP Jacket are as follows:
PVC cable resistant to oxidation and degradation, it is commonly used for horizontal runs from the wiring center.
LSZH cable has a special flam-retardant coating, it is between floors in a building.
OFNP cable is space within the building created by building components, design for the movement of air. It is usually work for vertical runs beween floors. 
 

How to Choose The Right Fiber Optic Cable Type on OM3 or OM4?

The difference of OM4 and OM3 fiber mode as the following
OM4 was developed specifically for VSCEL laser transmission and allows 10 Gig / second link distances of up to 550 Meters (compared to 300M with OM3).
The effective modal bandwidth for OM4 is more than double that of OM3.

For OM4 patch cable it is 4700 MHz.km while for OM3 it is 2000 MHz.km.
