Wave Division Multiplexing: Why it’s Good for Fiber

by www.fiber-mart.com A single optical fiber can carry a huge amount of bandwidth using Time-Division Multiplexing (TDM) and Coarse Wavelength Division Multiplexing ( CWDM ), which may be combined.   TDM was developed for digital telephony to send independent signals over a single fiber using synchronized switches at each end so that each signal appears on the line in short bursts, creating an alternating pattern. For audio/video, it is more efficient to convert any analog signals into digital and then combine them into one data stream using TDM.   CWDM was developed for the broadcast industry to combine signals from different bands onto a single fiber, using the wavelengths from 1270 nm through 1610 nm with a channel spacing of 20 nm (technically, it was shifted by 1 nm to 1271 to 1611 nm). Channel spacing ensures that minor signal drifting will not contribute to crosstalk or otherwise affect different wavelengths negatively, as well as, permits the usage of less sophistica

Something About WDM Transponder?

by www.fiber-mart.com In optical fiber communications, a  WDM transponder  is a common element that sends and receives the optical signal from a fiber. Maybe you have seen and used it many times. But do you really know it clearly? How much do you know? Today, this article is going to talk about something about WDM (Wavelength Division Multiplexing) transponder.   What's WDM Transponder?   WDM transponder, also named as fiber optic transponder, is an optical-electrical-optical (OEO) wavelength converter which is designed to perform an O-E-O operation to convert wavelengths of light. It plays a key role in WDM system, especially in DWDM (Dense Wavelength Division Multiplexing) system. Its name “transponder” is short for transmitter and responder, which clearly show its purpose. They are protocol and rate-transparent fiber media converters that support SFP, SFP+, XFP and QSFP transceivers with data rates up to 11.32 Gpbs. WDM transponders extend network distance by converti

How Multiplexing Techniques Deliver Higher Speeds on Fiber Optic Cabling

by www.fiber-mart.com The Different  Multiplexing  Techniques: Different multiplexing techniques are enabling the evolution of network speeds on fiber optic cabling.   Time Division Multiplexing is simply a way of transmitting more data by using smaller and smaller increments of time, and multiplexing lower data rate signals into a higher speed composite signal.     Space Division Multiplexing, more commonly known as parallel optics or parallel fibers, is a way of adding one or more lanes simply by adding one or more optical fibers into the composite link.   Wavelength Division Multiplexing is signaling simultaneously across multiple lanes segregated by different wavelengths (colors) of light that are multiplexed into and out of a single fiber.   Multiplexing Techniques Which Enable The Evolution of Network Speeds There are a range of different Multiplexing Techniques which enable the evolution of network speeds through fiber optic cabling. Let’s take a look at e
