What is the standard size of a 1U server chassis?

At present, there are strict regulations on the height and width of the server chassis. The height of the 1U server chassis is about 44.45 mm and the width is 19 inches. There is no special requirement for the length of the 1U server chassis. Non-standard small business cabinets with an internal vertical length of less than 650 mm need to use a 1U cabinet with a length of 525 mm. If your cabinet is an industrial control cabinet shorter than 550 mm, you need to use an ultra-short version with a length of 360 mm or 370 mm 1U server chassis, otherwise the server cannot be installed normally unless the cabinet door is not closed.

OLT Device is one of the most commonly used fiber optic equipment, which is also known as network device and FTTB FTTX equipment. Among these, one of the most commonly seen is EPON OLT. EPON OLT usually have uplink port and downlink port which supports data transfer, which is very important to WEB management function of OLT.
