The performance difference
Another key issue is "ceramic series connector" and "MT connector" performance difference. "Ceramic series connector," optical performance can be optimized in several ways, such as on connector ferrule inside the displacement and pressure adjustments, implementation of this procedure before the Assembly or adjustment by diameter and concentricity performance indicators can be ideal. More mainstream and main method of polishing process of ferrule end is to be, or to face coordination structure for a more streamlined design.
"Ceramic series connector" maximum insertion loss is generally divided into finished 0.15 to 0.5dB, return loss values for 45 to 55dB. "MT of connection device" plug core by molded Hou, each parts are has only of characteristics, due to fibre hole and boot pins of location is only of, so, can get of minimum insert loss was manufacturer on key molded process and check parameter of maintenance control ability of restricting, although we can under shaped bit tolerance for filter, but so do cost high and is takes, performance gain limited, and MT plug core of end surface structure on this a performance also constitute must limit. "MT connector" connector on the overall performance and "ceramic series connector" still have some gaps. MM and SM optical fiber type, maximum insertion loss of performance typically 0.50 to MT 1.0dB. SM echo loss performance of 50dB, multimode return loss values from 20 to 30dB.

Application status and prospect
MT ferrule structure principle, "of MT connector" for multiple connections. Communication between devices by the system integrated with the seed part, this application needs to be done in engineered optical loss budget of large amounts of fiber interconnection, connection loss less, so "of MT connector" optical properties and density of this type of connection is most ideal solution. Part of this seed is the interface of the access network, we can think of "MT connector" is a product of access network development.
"Ceramic series connector" usually used in optical loss budget and performance in dense secondary application, is the ideal connection between the backbone network devices. Because of their general use is show off, manufacturers and operators are well understood and accepted. Because of this, the "MT connector" use more broad space for development. This expert said, as long as you don't appear to replace optical access technology, operators under cost pressure, will gradually accept the cost cheaper "of MT connector".
