“sc”接头是标准方型接头，采用工程塑料，具有耐高温，不容易氧化优点。传输设备侧光接口一般用sc接头
“lc”接头与sc接头形状相似，较sc接头小一些。
“fc”接头是金属接头，一般在odf侧采用，金属接头的可插拔次数比塑料要多。
连接器的品种信号较多，除了上面介绍的三种外，还有mtrj、st、mu等
“/”后面表明光纤接头截面工艺，即研磨方式。
“pc”在电信运营商的设备中应用得最为广泛，其接头截面是平的。
“upc”的衰耗比“pc”要小，一般用于有特殊需求的设备，一些国外厂家odf架内部跳纤用的就是fc/upc，主要是为提高odf设备自身的指标。
另外，在广电和早期的catv中应用较多的是“apc”型号，其尾纤头采用了带倾角的端面，可以改善电视信号的质量，主要原因是电视信号是模拟光调制，当接头耦合面是垂直的时候，反射光沿原路径返回。由于光纤折射率分布的不均匀会再度返回耦合面，此时虽然能量很小但由于模拟信号是无法彻底消除噪声的，所以相当于在原来的清晰信号上叠加了一个带时延的微弱信号，表现在画面上就是重影。尾纤头带倾角可使反射光不沿原路径返回。一般数字信号一般不存在此问题。

sc connector is standard type connector, adopt theengineeringplastics, has a high temperature resistant, not easy tooxidation.optical transmission equipment side interface generallywith scconnectors
lc joint with sc connectors shape similar to that of thescconnectors.
metal joint, fc connector is generally adopted in odf side,metaljoint is much larger than the number of pluggable plastic.
the variety of connector signal is more, besides describedabovethree, mtrj, st, mu, etc
/ show that optical fiber connector section behind theprocess,the grinding method.
pc in the telecom operators of the most widely used inequipment,the joint section is flat.
upc attenuation is smaller than the pc, commonly usedinequipment with special needs, some foreign manufacturers odfframeinternal jump fiber is fc/upc, mainly to improve the index oftheodf equipment itself.
in addition, in the early days of radio, film and televisionandcatv is the application of more apc model, its tail fiberheaduses the angle of end face, can improve the quality of tvsignal,the main reason is that television signals is to simulatethe lightmodulation, when the joint coupling surface is vertical,thereflected light back along the original path. because offiberrefractive index distribution non-uniform coupling surfacewillreturn again, at this time although energy is small but itisimpossible to completely eliminate noise due to the analogsignal,so the equivalent of a superimposed on the original clearsignalwith a weak signal delay, show on the picture is double. tailfibercan make the headband angle reflection not back along theoriginalpath. general digital signal are not usually presentthisproblem.
