Optical Amplifier – EDFA (Erbium-doped Fiber Amplifier) for WDM System

Optical amplifiers serve as an integrated part of long haul data transmission. The most prominent feature of optical amplifier is that the device can amplify optical signal directly without the need to convert the signal into an electrical one before amplifying. EDFA (Erbium-doped Fiber Amplifier) is the one type of many different optical amplifiers that can achieve signal amplification over long-hual optical communication.Optical Amplifier BasicsWhen transmitting over long distance, the optical...

What Is OTN — Optical Transport Network?

With the explosion of digital traffic and the ever-growing array of bandwidth-hungry applications, OTN (Optical Transport Network) evolves from point-to-point DWDM remedies to scalable and robust optical networking applications that cater to a wide variety of client signals with equally-varied service requirements. Carriers are also placing particular emphasis on OTN in the Metro area, where it is shifted rapidly from SONET/SDH to WDM (wavelength-division multiplexing). With the goal of boosting...

Guideline for Fixed Fiber Attenuator

As a beginner in fiber optic network, I used to think that the optical power should be as strong as possible. Even sometimes we use optical amplifiers to improve the optical signal. So what is the fiber attenuator used for? As we know, the source of the single mode fiber is laser, the power of which is extremely strong. Therefore we can use single mode fiber to achieve long distance transmission. But, if the transmission distance over single mode fiber is too short, too much light may overload a...

18 Channel CWDM Mux/Demux for 10G Network

Imagine turning a cottage into a majestic skyscraper without any innovation or construction. This is what Wavelength-Division Multiplexing (WDM) allows with your existing fiber optic network. Without deploying additional optical fiber, WDM network mux multiplexes multiple optical signal on a single optical fiber by using different wavelengths, which greatly relieves fiber exhaustion and extends link capacity. WDM technology comes into two flavors—CWDM and DWDM. In this article, we’re gonna explo...

Do You Know All These Terminologies of WDM Technology?

As an unprecedented opportunity to dramatically increase the bandwidth capacity, WDM (Wavelength Division Multiplexing) technology is an ideal solution to get more bandwidth and lower cost in nowaday telecommunications networks. By virtue of fame, WDM becomes a household word now. Yet, most of the time, we only know what is “WDM” but do not really know WDM technology. Actually, there are various of terminologies used in WDM that are always a headache for us. Now, let’s see what are they. WDM ...
