Cable Management Bar: What Role it Plays in Rack Cable Management

I think it’s safe to say that in most data centers or server rooms, cable clutter is an annoying issue that’s hard to ignore. In recent years, more and more data centers and server rooms feature high density and large capacity, usually accompanied by a large number of copper cables or fiber optic patch cables to connect the entire network….


Understanding 1000BASE-LX SFP and 1000BASE-LH SFP

As the industry of optical communication develops rapidly, the design of optical fiber transceiver is more and more diversified, so as to meet the needs of Gigabit Ethernet. Therefore, various types of mini GBIC (SFP, Small Form-factor Pluggable) and SFP+ emerged. Gradually, we always see 1000BASE-LX SFP and 1000BASE-LH SFP on many websites. However, many people are puzzled about them….


Cat6 vs Cat6a Cable: How They Differ From Each Other?

An Ethernet cable, one of the most commonly used network cables in wired networks, connects devices in local area networks, such as computers, routers and switches. In the past few years, Cat6 cables and connectors have become a necessity for new buildings to support Gigabit network applications and to support up to 250MHz of bandwidth. Subsequently, the Cat6a, which supports…


SFP, LC and SC Connectors

Glancing at modern network devices, people will see different built-in ports for different connections. For example, we use the USB interface in mobile phones to use RJ45 ports in copper wire switches. However what about SFP port? SFP ports are the built-in interfaces of various devices, including Gigabit switches, SFP switches, and network interface cards (NIC). Today we will talk…

What are Optical Fiber and Fiber Optic Cable?

With the development of science and technology, the demand for large-scale communication construction is increasing. The fiber optic cable industry has developed rapidly and has formed a complete industrial chain from fiber preform, optical fiber, fiber optic cable, sensors, optoelectronics, and components. Fiber Optic Cable Definition To get clear what is fiber optic cable here starts from the fiber optic…
