Tsinghua Tongfang RJ11 telephone crystal head promotional offers Tongfang CT-RJ11 telephone crystal head Kunming latest offer Tongfang RJ11 telephone crystal head, RJ11 connector and RJ45 interface is very similar, but only four pins (RJ45 to 8). In a computer system, RJ11 modem is mainly used to debug modem connection. Tsinghua Tongfang phone crystal head RJ11 generally refers to six positions (6-pin) modular jack or plug. This connector is no international standard and is mentioned in the common cabling standards. Moreover, the name often used for the 4-pin version of the modular connector, causing confusion. In common cabling standards, there is no single reference to 'RJ11' exposition, all connected devices must be 8-pin. Therefore, RJ11 and RJ45 interoperability and compatibility are not written. This name has been registered on behalf of RJ jack (Registered Jack), it is derived from the Bell System USOC (Universal Service Ordering Codes, general service classification code) code. USOC is a series of Registered Jack and wiring, it is developed by the Bell System, used to connect the user's device to the public network. FCC regulations control the use for this purpose. FCC (Federal Communications Commission) on behalf of the US government released a document specifies RJ11. RJ11 is the generic name for the Western Electric Company (Western ElectricCo) developed connectors. Its shape is defined as a 6-pin connector devices. Formerly known as WExW, where x 'active', contacts or wire needle. For example, WE6W have all six contacts, numbered 1 through 6, WE4W interface using only 4-pin outermost two contacts (1 and 6) do not, WE2W use only the middle two pins. For RJ11, sources of information are contradictory, it may be 2 or 4-pin 6-pin connectors. More confusion is, RJ11 and not only to represent the 6-pin connectors, it also refers to the 4-pin version. RJ45 and RJ11: different standards, different sizes due to the size difference between the two (RJ11 4 or 6-pin, RJ45 8-pin connector devices), apparently RJ45 plugs can not be inserted into the RJ11 jack. The reverse is physically feasible (RJ11 plug is smaller than the RJ45 jack), whereby mistaken or two should be able to work together. In fact not the case. It is strongly recommended not to RJ11 plug for the RJ45 jack. Since RJ11 is not internationally standardized, its size, insert strength, and so there is no uniform insertion angle connector design requirements in accordance with international standards and therefore can not ensure interoperability. They may even lead to the destruction of both. Since the RJ11 plug is smaller than the RJ45 jack plug on both sides of the plastic part will be damaged inserted metal pin jack.
