What size optical splitter is used in Europe
Rack-mount Splitter: Today, 1U and 2U are the two common sizes of rack mount optical splitters , with 1U rack mount optical splitters being more commonly used. A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system. The optical network system uses an optical signal coupled to the branch distribution. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. Cassette splitter is the most commonly used in the PON networks, and it has the complete protection for inner optical components and cable, as well as the convenient installation and easy to use, but its volume is relatively large. It's mainly used for various of connection and distribution. Fiber optic splitter is a passive optical device used to distribute optical signals, which can divide input optical signals into multiple outputs to meet the fiber optic access needs of multiple terminal devices.
