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 sma…

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 interf…

In the past, because of low cost and compatibility with existing LANs, 100Mb/s Ethernet was very popular. As people’s increasing demands for faster delivery of information, high bandwidth Ethernet LAN is evolving. 1000BASE (1 Gbps Gigabit …

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 metho…

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 mult…

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 o…

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 device…

Since the invention of optical fibers in the early 1970s, the use of and demand for optical fiber today are quite numerous. With the explosion of information traffic due to the Internet, electronic commerce, computer networks, multimedia, …

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 ca…

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 wa…

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 refracti…

As the development of computer science technology, 10 Gigabit Ethernet is widely used in our daily life. 10 Gigabit Ethernet means a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabytes per s…

WDM is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light. It can be divided into different wavelength patterns, conventional/coarse (CWDM) and dense…

SFP transceivers are commonly used and necessary in our daily life. And there are two kinds: single mode SFP and multi-mode SFP. However, maybe most people don’t know these two SFP transceivers are different. The following are the differen…

In recent years, Fiber to the Home (FTTH) has started to be taken seriously by telecommunication companies around the world, and enabling technologies are being developed rapidly. There are two important types of systems that make FTTH bro…

Introduction SFP (Small Form Pluggable) optical module is a compact transceiver used for both telecommunications and data communication applications. It can interface a network device motherboard (for a switch, router, media converter or s…

SFP+ Transceivers are the upgraded version of the former SFP transceivers (mini GBIC), with higher data rate and new industrial standards. It is smaller than any of the currently shipping form factors and offers a very high density per lin…

Both Passive CWDM and DWDM have been viable solutions in the telecommunications industry, but now, 10G Ethernet is appearing to be the most preferred solution over CWDM, everyone is migrating to the use of 10G Ethernet. This encourages man…
