1) Short-distance network cabling
The short distance range is generally less than 1 kilometer, and some manufacturers define this as within 500. Because the maximum transmission distance of network cables is 200m (the limit is 300m), exceeding this value will cause attenuation that can affect signal transmission.
The 1000BASE-T SFP optical module supports 10/100/1000 adaptive and Auto MDI/MDIX (receiving and transmitting interconnect), and can be used in conjunction with Category 5 unshielded network patch cords, with a transmission distance of up to 100m. Its function is to achieve short-distance transmission without interference (minimal interference).
The 1000BASE-SX SFP optical module is compatible with the IEEE 802.3z 1000BASE-SX standard and can be used in 50μm/62.5μm multimode optical fiber links, with a maximum transmission distance of up to 550 meters.
2) Long-distance network cabling
The 1000BASE-EX and 1000BASE-ZX SFP optical modules can be used in conjunction with single-mode optical fibers and are suitable for long-distance network transmission. Among them, the transmission distance of the 1000BASE-EX SFP optical module can reach 40 kilometers, and that of the 1000BASE-ZX SFP optical module can reach 80 kilometers.
Note: When single-mode optical fibers (SMF) are used over shorter distances, to prevent the receiver from being overloaded, an optical attenuator needs to be inserted in the link. Overloaded optical power can damage the device. More importantly, it can lead to signal loss and the generation of bit errors.
