OM1 OM2 OM3 Multimode Fibre
According to ISO/IEC 11801, which was made in September 2002, multimode fibre are classified and renamed to be OM1, OM2, and OM3. OM1 multimode fibre refer to traditional 62.5/125 cables, OM2 multimode fibre refer to traditional 50/125 cable, OM3 is the name of 10 Gigabit multimode fibre optic cables, which is also 50/125 diameter. The 10g fibre optic cable is also called "Laser Optimized Cable".

10-Gigabit Ethernet
Standard for Ethernet network is IEEE 802.3. Ethernet is widely used local computer networks.
In the early times, standard Ethernet bandwidth is only 10Mbps; it is run on copper networks.
The second generation is fast Ethernet, with 100Mbps and 1000Mbps rate, fibre optic applications adopted was with the fast Ethernet. With development of multi media applications, more and more bandwidth is required; people are looking for solution of 10Gbase Ethernet. Standard for the 10G Ethernet is IEEE 802.3ae. 10G fibre optic cables are developed for these applications. To make it easy to identify, people use the special color Aqua for this 10g fibre optic cables, it is different from the traditional orange color multimode fibre cables.
