Optical Fiber Circulator Multiple Circulator Chassis
Multiple Circulator Chassis
1. Dimensions and interface requirements
1.1 Appearance and Dimensions The circulator is packaged in a 2U chassis, with FC adapter output on the front and rear panels. The size of the case is 430×250×89mm, made of aluminum alloy Al5052, and the surface of the case is sandblasted and blackened. The thickness of the board is 1.5mm, and the front panel of the chassis has a handle. There are 54 FC single-connection ports on the front and rear panels, with port silk-screening. The diagrams below are for reference only.
1.2 Interface requirements 2U chassis front and rear panel interface adopts FC/APC adapter interface output, FC/APC optical fiber connector. The front panel has mounting positioning holes and handles. Channel identification: silk screen identification.
