More about the E-2000 XB

Expanded Beam Technology

In a lensed-fiber optical connection, the alignment accuracy between the fiber, the lens and their mating counterpart must be kept very tight in order to achieve proper insertion losses. Diamond has developed an ultra-low tolerance optical sub-assembly utilizing a micro lens and ferrule embedded in a high precision ceramic sleeve. This is accomplished through ultra-precise machining of ceramics and opto-mechanical components. Our a vertically integrated manufacturing process, from the raw materials to the finished product, ensure consistent quality. The result is a high performance, exceedingly reliable lensed-ferrule assembly offering compact size and highly repeatable low insertion loss.

More about the technology

Same, but different – a copy is never as good as the original

Diamond is the inventor of the world-famous E-2000 fiber optic connector. The low insertion loss values, which can be guaranteed by utilizing the company’s Active Core Alignment process, making the Diamond E-2000 often copied, but unrivalled. In addition, all Diamond connectors are manufactured and inspected using clearly defined processes and only high-quality materials.
