With the increasing deployment of fiber in the LAN and WAN, especially for building and campus backbone installations, the small form factor (SFF) fiber-optic connector is more and more popular. One kind of transceivers called SFP is a small form-factor pluggable transceiver. It’s used for both...

SFP is short for small form-factor pluggable. It’s a compact, hot-pluggable transceiver used for telecommunication and data communications. The form factor and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for...

Fiber optic patch cords are also known as fiber optic jumpers or fiber optic patch cables. Fiber optic patch cords are designed to provide optical connection for fiber networks within structured cabling systems. It’s a quick and easy method for routing fiber patches in data centers, head-ends,...

WDM (wavelength division multiplexing) technology transmitting multiple signals on a single optical fiber by using different wavelengths to carry each signal has been used since 1980s. In the middle of 1990s, dense wavelength division multiplexing (DWDM) enabled carriers to extend the capacity of...

In 2006, the IEEE 802.3 working group formed the Higher Speed Study Group (HSSG) and found that the Ethernet ecosystem needed something faster than 10 Gigabit Ethernet. Because the growth in bandwidth for network aggregation applications overpasses the capacities of networks employing link...

Signals travel through fibers over large distances with attenuation. Then the optical amplifiers are needed in the CWDM (corse wavelength divsion multiplexing) and DWDM (dense wavelength divsion multiplexing). Optical amplifiers are devices that can amplify optical signals directly...

People find it’s very difficult to discover the perfect solution for cabling infrastructure. The one is that it should depend on many complex circumstances. The other is because people don’t know very well about the properties of copper cables and optical cables. Copper wires transmit electrical...

In 1980s, the first generation called wideband WDM (wavelength division multiplexing) using two widely spaced wavelengths in the 1310nm and 1550nm appeared. In early 1990s, the second generation narrowband WDM with two to eight channels was used. But people would never be satisfied with network...

Introduction
Fiber optic patch cord is also known as fiber optic jumper or fiber optic patch cable. It’s made of two parts: optical connector and fiber optic cable. Inside of the fiber optic patch cord, there is a core with a high refractive index surrounded by a coating with a low refractive...
