DOME Fiber Closure Was Originally Used For Gigabit Ethernet

Given the various splice options available to today's fiber network planners, determining the best fiber optic connector for FTTH can be very difficult. Therefore, under the drive of cost, availability or choice of previous use, there is not much consideration for connector selection. However, each DOME Fiber Closure connector has its own unique design, so there are advantages and disadvantages. Over time or depending on the size of the project, this can have a huge impact on deployment speed and cost.

So what is the difference, what do they mean for your implementation? This generic fiber optic connector table outlines the advantages and disadvantages.

1. SC connector

The SC was developed by the Japan Telegraph and Telephone Corporation (NTT) laboratory in the mid-1980s and was one of the first connectors to enter the market after the appearance of ceramic ferrules. The SC is sometimes referred to as a "square connector" with a spring loaded ceramic ferrule on the push-pull end face. Originally used in Gigabit Ethernet networks, it was standardized in 1991 as the telecommunications specification TIA-568-A, and has become increasingly popular as manufacturing costs have decreased. Due to its excellent performance, it has dominated the fiber industry for more than a decade, and only ST can compete with it. For the past three decades, it has remained the second most common fiber optic connector for polarization-maintaining applications. SC is ideal for data communications and telecommunications applications, including point-to-point and passive optical networks.

2. LC connector

It was considered by some to be a modern alternative to SC connectors, and its introduction was less successful, in part because of the inventor's initial high licensing fees. Also a push-pull connector, the LC uses a latch instead of an SC locking tab and uses a smaller ferrule, which is called a small connector. Half of the SC connector's footprint makes it popular in data communications and other high-density patch applications because it combines small size and latch-up capabilities, making it ideal for densely populated racks/panels. With the introduction of LC-compatible transceivers and active network components, its steady growth in the FTTH space is likely to continue.

3. FC connector

FC is the first fiber optic connector to use ceramic ferrules, but unlike plastic bodies SC and LC, it uses round screw-type fittings made of nickel or stainless steel. The end face of the connector is properly inserted by means of the alignment key and then screwed into the adapter/jack using a threaded collet. Despite the added complexity of manufacturing and installation, it is still the preferred connector for precision measuring equipment.

Originally used in data communications and telecommunications applications, its use has been reduced since the introduction of SC and LC. They offer similar performance to FC, but both have cheaper components and are faster to connect. However, the FC's screw-in chucks make it particularly effective in high-vibration environments, ensuring that the spring-loaded ferrules fit securely.
