Molex enterprise network cabling department in view of new multimode cable standards development, recently urged users to install fiber optic cabling system, pay attention to selection for application to provide full support of the manufacturers, and is currently on the market are more commonly three kinds of small connector ( SFF ) were compared, presenting to the user using the recommended.
To choose a reliable manufacturer
Small connector function and traditional SC connector and ST connector is the same, but the smaller, per unit area is thus achieved a higher density of fiber core end is connected with a capacity of. This technology is driven the user asks to reduce volume to accommodate higher density of active equipment.
Molex enterprise network cabling department thinks, and structured cabling industry any emerging standards, fiber standard approval time longer than expected. This will be in standard approval prior to installation in early SFF connector end users will have a great impact, their system may become proprietary systems, facing issues of interoperability.
Molex enterprise network cabling ministry points out, although each connector manufacturers will be updated according to the scheme design of hardware connectors, and try to ensure the program revision, the revised scheme through the downward compatibility test connector. However, the manufacturer does not actually responsible for ensuring interoperability with other manufacturers. This can be problematic, as a matter of fact, in a number of projects had caused problems. Reliable manufacturers will ensure that meet the standard, and the potential of any influence inform customers. Therefore, it is not only the product selection problem, and manufacturers can provide good technical support, and participate in the standard setting process is the manufacturer has this kind of ability is one of the mark.
The advantages and disadvantages of the3 kinds of SFF
In order to provide recommendations for the use of Molex enterprise network cabling, compared to the current common market in three SFF solution: MT-RJ, LC and 3M VF45Volition. They have a higher density of fiber core end is connected with the ability, in the traditional simplex SC connector volume can be connected to the two optical fibers, but in the use of the advantages and disadvantages of.
Molex enterprise network cabling department thinks, MT-RJ connector has the advantages from many active equipment manufacturers to adopt, so demand is very big. But for the final user not exist patch problem, because during the installation process has been completed. Its shortcoming is the standard problem. As a result of any SFF connector without interoperability standard, therefore it does not ensure the different providers of connector can realize interoperability.
LC connector is also popular, active equipment manufacturers use greatly promote its popularity. It is to the end user without polarity, it uses the traditional, proven ferrule technology design. The shortcomings of LC and MT-RJ, no interoperability standard. In addition, the cost is high, market coincides with the telecommunications market to further decline, further problems.
Third kind of common SFF connector is the 3M VF45Volition. Molex enterprise network cabling department believes that the biggest advantage is low cost, price is only half of the other SFF scheme. And it adopts pure connector and socket design, does not require adapter. But because there is no large active equipment manufacturers with the connector, thus the market on the active equipment co.. It uses optical fiber type is also problematic, permanent bending ( the fiber clamp in the groove ) on the durability and performance impact. Because the optical fiber structure, it also requires manufacturers to provide special cable assemblies.
While pointing out that the current SFF portion of the connector disadvantages and potential defects, Molex enterprise network cabling department emphasizes, this does not mean that the SFF connector will always have problems, the company still recommend users in relation to the standard has not been finally introduced, such as required for installation of optical fiber, it must be carefully chosen, the key is to find the user can provide the full support of the irresponsible manufacturers.
