Typical CWDM Optical Elements and Features

CWDM VS DWDM differ noticeably in the spacing between adjacent wavelengths. DWDM packs many channels into a small usable spectrum, spacing them 1 to 2 nm apart; DWDM systems support a high channel count, but also require expensive cooling equipment and independent lasers and modulators to ensure that adjacent channels [ Continue reading…]

What is Ribbon Fiber Optic Cable

by www.fiber-mart.com Ribbon fiber optic cable is a typical fiber optic cable. Unlike beam optical cable, ribbon fiber optic cable is arranged into a strip. Ribbon fiber optic cable is a convenient solution for space and weight problems. The cable ribbons are actually coated optical fibers placed side by side, encapsulated [ Continue reading…]

What should know Before Selecting CWDM SFP Transceivers

As an extension of wavelength division multiplexing (WDM), coarse wavelength division multiplexing (CWDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber through the use of different wavelengths (i.e., colors) of laser light. A CWDM SFP (Small Form-factor Pluggable) transceiver is a hot-swappable [ Continue reading…]

comparison between CWDM and DWDM

by www.fiber-mart.com CWDM, just as DWDM, use multiple light wavelengths to transmit signals over a single optical fiber. However, there are still some differences betwwen the two techologies in many ways.   CWDM uses a 20-nm wavelength spacing that is much wider than the 0.4 nm for DWDM. The wider [ Continue reading…]

Something about Optical Circulator

by www.fiber-mart.com The utilization of optical circulator starts from the 1990s, and now it has become one of the important elements in advanced optical communication systems. Similar to the function of an electronic circulator, an optical circulator is used to separate optical signals that travel in opposite directions in an [ Continue reading…]

Different Ports on WDM Mux/Demux

by www.fiber-mart.com In the WDM (wavelength-division multiplexing) system, CWDM (coarse wavelength-division multiplexing) and DWDM (dense wavelength-division multiplexing) Mux/Demux (multiplexer/demultiplexer) modules are often deployed to join multiple wavelengths onto a single fiber. Multiplexer is for combining signals together, while demultiplexer is for splitting signals apart. On a WDM Mux/Demux, there are many kinds [ Continue reading…]

Choose Duplex Fiber or MPO/MTP Fiber for 40G Solutions?

by www.fiber-mart.com There’s been a lot of talk lately surrounding bidirectional 40 Gb/s duplex applications, or BiDi for short. Currently offered as a solution by Cisco®, BiDi runs over duplex OM3 or OM4 multimode fiber using QSFP modules and wavelength division multiplexing (WDM) technology. It features two 20 Gb/s channels, [ Continue reading…]

Which Fiber Loopback Should I Use for My Transceiver?

by www.fiber-mart.com In telecommunication, fiber loopback is a hardware designed to provide a media of return patch for a fiber optic signal, which is typically used for fiber optic testing or network restorations. When we need to know whether our fiber optic transceiver is working perfectly, we can use a fiber [ Continue reading…]
