Understanding 10GBASE-LR Optical Module
10GBASE-LR is a 10-gigabit Ethernet standard that was developed in order to extend the reach of 10 Gigabit Ethernet from 100 meters to 10 kilometers. This optical module has been designed for use in data centers and other high bandwidth applications.
The 10GBASE-LR standard was created by the IEEE 802.3ae task force, which is responsible for developing standards for Ethernet networks. It is an extension of the IEEE 802.3ae standard, which specifies the original 100 meter reach of 10 Gigabit Ethernet and its variants: 1000BASE-T (10/100/1000 Mbps) and 1000BASE-X (10/100/1000 Gbps). The IEEE 802.3ae task force felt that there was a need to extend the reach of these standards to make them viable for use at long distances in data centers, on ships or other large installations where it would be impractical to install new wiring or use expensive wireless connections like microwave links.
10GBASE-LR is a standardized 10 Gigabit Ethernet (10 GbE) optical module. It is used to provide 10 Gbit/s bidirectional data transfer rates over distances of up to 10 kilometers. 10GBASE-LR was designed for use in long reach applications, and it operates at a wavelength of 1310 nm with a maximum reach of 10 km. It can also be used in shorter reach applications at distances of up to 2 km. This is achieved by using the same module with different optics and connectors.
10GBASE-LRM vs. LR Optical Module Comparison
The 10GBASE-LRM and LR optical modules are two different types of physical media, which can be used in a network. Their features, applications, and compatibility are different.
The 10GBASE-LRM is a high-performance fiber optic module that can provide data rates up to 10Gbps over long distances. It has a maximum reach of 100km (62 miles) and is mainly used in data centers or for long distance connections. The LR optical module is a low-cost fiber optic module that can provide data rates up to 1Gbps over short distances. It has a maximum reach of 300m (984 feet) and is mainly used in LANs or for short distance connections.
The 10GBASE-LRM provides higher bandwidth than the LR optical module, but it’s also more expensive and has lower reach. The LR optical module provides lower bandwidth than the 10GBASE-LRM but it’s cheaper with higher reach.
The 10GBASE-LRM is a 10 gigabit Ethernet standard using a long reach multimode fiber (LR) and the LR optical module is a 10 gigabit Ethernet standard using single mode fiber (SM).
The difference between the two lies in their transmission distance. The 10GBASE-LRM has a transmission distance of up to 100 km and the LR optical module has a transmission distance of up to 300 km.
