1.1 The grinding angle is different.
PC indicates Physical Contact. PC is micro-spherical grinding and polishing, the ferrule surface is ground into a slight sphere, and the optical fiber core is located at the highest point of bending, which can effectively reduce the air gap between the optical fiber components, so that the two endfaces reach physical contact.
UPC(Ultra Physical Contact) : hyper physical endface. The UPC connector endface is not completely flat and has a slight curvature to achieve more accurate docking. UPC is based on PC more optimized endface polishing and surface finish, the endface looks more dome-shaped.
TheAPC (Angled Physical Contact) is called the angled physical contact, and the endface of the optical fiber is usually ground to an 8° angled surface. The 8° bevel makes the endface tighter and reflects light through its bevel Angle to the cladding rather than directly back to the light source, providing better connection performance.
2.2The insertion/return loss is different
Different grinding methods determine the fiber transmission quality, which is mainly reflected in return loss and insertion loss. Insertion Loss is the loss of a signal through a connector or cable. In general, the typical insertion loss of PC, UPC, and APC connectors should be less than 0.3dB. UPC/PC connectors are generally easier to achieve with low insertion losses due to smaller air gaps compared to APC connectors. Insertion losses can also be caused by dust particles between the end faces of the connector.
Return Loss, also known as reflection loss, is a parameter that indicates the reflection performance of a signal. It is usually represented by a negative dB value, the higher the parameter of the value, the better. The end face of the APC connector is inclined polished,therefore, the return loss of APC connectors is usually better than that of UPC connectors. Under normal circumstances, the return loss of optical fiber jumper using PC grinding is -40dB. The UPC return loss is higher than that of a PC, generally at -55dB (or even higher). The APC industry standard return loss is -65dB. When the UPC connector is used, some of the reflected light will be emitted back to the light source, while the oblique endface of the APC connector will cause some of the reflected light to reflect atan Angle to the cladding, thus reducing more reflected light back to the light source. This is the main factor that causes the difference in return loss.
Armored cable consists of a cable surrounded by a steel tube to protect it from moisture and abrasion. Such armored cable can be much stronger than regular cable due to its high tensileforce. GoodFtth's armoured tactical cable is an extremely robust and flexible cable which is widely used by the military, in oil and gas,etc. It is especially suitable for temporary installations. The tactical cable combines features such as soft, flexible, light weight, easy to carry; tension resistance, pressure resistance and high mechanical characteristics,etc. The flexible outer sheath makes the cable easy to roll in and out, even in the cold weather. The cable can withstand temporary exposure to oil and other chemicals.
GoodFtth is offering armoured tactical cables mainly less than 48 fibers,can be terminated with all kinds offiber optic connectors as you specify,reach GoodFtth for details.
Why the price is so different for the optical fiber terminators?This is due to many factors, first of all, the raw materials, production process, test techniques, quality standards, packaging methods and quantities are the important factors to reflect the price.
When customers buy optical fiber terminators, if they are not very concerned about the performance and requirements of these products, it may cause some unnecessary misunderstandings, the material of the products, production processes, testing methods, quality standards, packaging methods,etc. these are very important factors to reflect the price. In line with the responsibilityfor customers and the importance of quality, GoodFtth Communication Equipment requires that all products are required to have 100% quality assurance before export.Our after-sales and technical department will provide the testing records and relevant information at the time of receiving customers' feedback to better service. GoodFtth stands for good quality, fast response and assured service

Fabricated using silica optical wave guide technology to distribute optical signals accurately and evenly with minimal loss providing a low cost light distribution solution with small form factor and high reliability.
Constructed with the quality clear curve Bend Insensitive Fiber (BIF) glass for the greatest installation speed and efficiency with high transmission rates and virtually no distortion.
MPO is theindustry acronym for “multi-fiber push on.” These connectors have more than 1 fiber in a single ferrule and snap into place by a mechanical mechanism. There are many designs of MPO on the market for the various manufacturers. As with any type of connectivity product, the performance and cost of these vary considerably and some have distinct features that enable better “overlife”performance. Some MPO connectors are inter-matable with different brands,others are not. This intermateability is dependent on how close the design is to the standard.
The term MTP (Multifiber Termination Push on ) is a registered trademark of US Conec. This is the termused by US Conec to describe their connector. The US Conec MTP product is fully compliant with the MPO standards. That is to say, the MTP connector is a high performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.
The data center wiring system consists of two parts: SANnetwork wiring system and network cabling system. MTP/MPOtrunk cable,as acost-effective alternative to time-consuming field termination,is designed forhigh-density fiber patching in data centers which need space saving and reducecable management troubles, is terminated with an MTP/MPO multi fiber connectorson both ends,each connector uses a multicore type fiber optic cable whichcontains multi fiber in one single jacket, so that the MTP/MPO trunk cables cangreatly save space and can be very convenient. MTP/MPO cable assemblies provideup to 144 fiber connections in asingle point, reducing the physical space andlabor requirement, while providing the same bandwidth capacity of a multi-fibercable with individual fiber connector terminations per cable.
MTP/MPO trunk cable assemblies facilitaterapid deployment of high density cabling in data centers to reduce networkinstallation or reconfiguration time and cost. GoodFtth provides preferable datacenter solution for customers.
