Some time ago, an article was published, exactly one friend did not understand the transmission distance of the optical fiber, Xiao Bian specifically turned over the information, hoping to help friends who do not understand the cable, fiber optic, bridge transmission distance to solve the doubt.
A network cable
The effective transmission distance of Category 5 and Category 6 cables is generally 100 meters. If you want to increase the transmission distance, you need to install repeaters between the two twisted pairs. You can install up to 4 repeaters. If four repeaters are installed to connect five network segments, the maximum transmission distance is 500 meters.
In addition, the coaxial cable Ethernet transmission distance is about 100 meters, and the thick cable is about 500 meters.
Second, optical fiber
1. Transmission rate 1Gb/s, 850nm (fibre diameter)
a. Common 50μm multimode fiber transmission distance 550m,
b. Ordinary 62.5μm multimode fiber transmission distance 275m,
c, new 50μm multimode fiber transmission distance 1100m.
2. Transmission rate 10Gb/s, 850nm,
a. Ordinary 50μm multimode fiber transmission distance 250m,
b. Ordinary 62.5μm multimode fiber transmission distance 100m,
c. The new 50μm multimode fiber has a transmission distance of 550m.
3. Transmission rate 2.5Gb/s, 1550nm,
aã€g.652 single-mode optical fiber transmission distance 100km,
b, g.655 single-mode fiber transmission distance 390km
4. Transmission rate 10Gb/s, 1550nm,
a, g.652 single-mode optical fiber transmission distance 60km,
b, g.655 single-mode fiber transmission distance 240km
5. Transmission rate at 40Gb/s, 1550nm,
a, g.652 single-mode optical fiber transmission distance 4km,
b, g.655 single-mode optical fiber transmission distance 16km
In addition:
1000base-SX: Single-fiber 1000Mbps baseband transmission system. 1000BASE-SX also corresponds to the 802.3z standard and can only use multimode fiber. The 1000BASE-SX fiber used is: wavelength is 850nm, divided into 62.5/125μm multimode fiber, 50/125μm multimode fiber. The maximum transmission distance of 62.5/125μm multimode fiber is 260m.
1000BASE-LX: LX stands for long wavelength. The main fibers used are: 62.5 μm multimode fiber, 50 μm multimode fiber, and 9 μm single mode fiber. The maximum transmission distance of the multimode fiber is 550m, and the maximum transmission distance of the single mode fiber is 3km.
Third, wireless bridge:
1, 5.8G wireless bridge ST5023PRO, transmission distance 100KM, often used for 30-100 km long-range wireless transmission projects.
2, MESH wireless bridge ST5801GB-M, transmission distance 30KM, often used in 10-30 km long-distance networking project.
3, high-power wireless bridge ST58T8G-N, transmission distance 10KM, commonly used in 3-10 km long-range wireless transmission projects.
4, outdoor wireless bridge ST5817H, transmission distance 3KM, often used for 1-3 km of close-range wireless monitoring, wireless transmission projects.
In addition, Teng Yuan Zhi Tuo has COFDM wireless video transmission equipment , 3G/4G wireless video monitoring equipment, analog wireless monitoring equipment and other types of wireless transmission, wireless monitoring equipment, are interested, you can log in Tengyuan Chi extension, click on the "product Center" view.
