What is the difference between OM3 and OM4 fiber.
Identified by ISO 11801 standard, multimode fiber optic cables can be classified into OM1 fiber, OM2 fiber, OM3 fiber, OM4 fiber and newly released OM5 fiber. The next part will compare these fibers from the side of core size, bandwidth, data rate, distance, color and optical source in details. OM1 Fiber.Second, the design comparison of OM1, OM2, OM3, and OM4 fiber. 1. The traditional OM1 and OM2 multimode optical fibers are based on LED (Light Emitting Diode) as the basic light source, and OM3 and OM4 are optimized on the basis of OM2, making them suitable for the light source. For the transmission of LD (Laser Diode); 2. Compared with OM1 and OM2, OM3 has a higher transmission rate and.Both OM3 and OM4 are designed with Aqua jackets and 50.0 micrometers core size and are suggested for 10G, 40G and 100G Ethernet. Now OM1 and OM2 are gradually being replaced by OM3 and OM4. OS2 is the currently widely deployed in our fiber optic network, it has a core size of 9 micrometers.
Relative Size Comparison. The center of the fiber, or the Core, plays a big role in the quality and distance the signal can travel through the fiber. Core size is a big factor in how far the signal will travel. In general, the smaller the core the farther the optical signal (light pulse) will go before it needs regenerated. Later we will get into a bit more detail on Single Mode and Multi-mode.OM3 and OM4 are both laser-optimized multimode fiber (LOMMF) and were developed to accommodate faster networks such as 10, 40, and 100 Gbps. Both are designed for use with 850-nm VCSELS (vertical-cavity surface-emitting lasers) and have aqua sheaths.
Compare with OM1 and OM2, OM3 and OM4 are enhanced to support much higher data rates of 40 Gbps and 100Gbps in 40G and 100G Ethernet. Distance. Multimode fiber is typically used for short distance transmission. But the maximum reaches are varied in different multimode fiber types. Also, on account of different data rates, the transmitting distances are different. However, the common feature is.
