The OM3 patch cord is a 10-Gigabit multi-mode patch cord. The multi-mode fiber uses light-emitting diodes as the light source, allowing multiple beams of light to propagate in the fiber at the same time, thereby forming a mode dispersion. Mode dispersion technology limits the bandwidth and distance of multimode fiber. Therefore, the core wire of multimode fiber is thick, the transmission speed is low, the distance is short, and the overall transmission performance is poor, but its cost is relatively low. It is generally used in buildings or geographical areas. Location adjacent to the environment. Next, ETU-LINK will introduce the multi-mode fiber OM3 and the difference between OM3-150 and OM3-300.

OM3 fiber is a laser-optimized fiber type, which can provide a higher transmission bandwidth in a transmission window of 850nm. In a Gigabit network, OM3 can support a transmission distance of 550 meters, and in a 10 Gigabit Ethernet, OM3 can transmit up to 300 meters. In 40G/100G Ethernet, OM3 can be transmitted up to 100 meters.

The bandwidth of multi-mode fiber is 50MHz~500MHz/Km. OM3 can be divided into two series, namely OM3-150 and OM3-300. OM3-150 refers to the longest transmission distance of this patch cord type in 10 Gigabit Ethernet. 150 meters, OM3-300 refers to the maximum transmission distance of this patch cord type in 10 Gigabit Ethernet is 300 meters. In addition to the difference in transmission distance, the effective bandwidth of the two is also different. The effective bandwidth of OM3-300 is higher than that of OM3-150.

The high bandwidth of OM3 10G multimode optical cable at 850nm is designed to adapt to VCSEL laser light sources. VCSEL lasers are cheaper than traditional lasers, have better performance than LED light sources, and can be used in 10GB Ethernet transmission. The OM3 patch cord is aqua blue, and its outer sheath material can be divided into PVC sheath, LSZH sheath, OFNP sheath, and PVC sheath is very soft, anti-oxidation, suitable for horizontal and vertical applications in ventilated buildings; LSZH The sheath is low and halogen-free, suitable for horizontal structure wiring areas and data center computer rooms; OFNP sheath has the highest fire rating and is suitable for vertical operation between data center floors.

The OM3 10 Gigabit multi-mode optical cable of ETU-LINK adopts flame retardant sheath, which can prevent flame spread, smoke, acid gas and poison gas emission, and meet the transmission rate of 10Gb/s. It is usually used in the wiring environment of data center, and supports the transmission of 10G or even 40/100G high-speed Ethernet.
