Erbium is the element that makes the modern internet possible. While it may not be a household name, it’s the invisible force amplifying the data that travels across global fibre-optic networks. From seamlessly streaming video across oceans to performing highly precise, minimally invasive medical procedures, Erbium is a rare earth element that shapes how we connect and heal.
As a premier UK supplier of high-purity rare earths, Less Common Metals (LCM) understands the exacting demands of the telecommunications and medical sectors. Based in Ellesmere Port, UK, we supply the premium-grade Erbium required to keep global communications flowing and advanced medical lasers operating with pinpoint accuracy.

Erbium is a silvery-white, malleable solid metal belonging to the lanthanide series. It is classified as a “Heavy Rare Earth Element” (HREE). While the pure metal is relatively stable in air, its chemical compounds are famous for their strikingly beautiful, fluorescent pink colour. However, its true value lies in its unique optical properties when it interacts with light.
Erbium operates at the cutting edge of light manipulation. Its primary applications include:
Without Erbium, the infrastructure of the modern internet would simply collapse. Before the invention of EDFAs in the late 1980s, fibre-optic cables required expensive, slow electronic repeaters to boost signals. Erbium amplifiers revolutionised global telecommunications by allowing data to remain entirely in the form of light as it travels the globe. Hence, securing a reliable, high-purity supply of this heavy rare earth remains a top priority for the world’s leading tech and infrastructure companies.
