Although signals propagating in optical fiber suffer far less attenuation than in other mediums, such as copper, there is still a limit of about 100 km on the distance the signals can travel before becoming too noisy to be detected. Before the commercialization of Optical Amplifiers, it was necessary to electronically regenerate the optical signals every 80-100 km in order to achieve transmission over long distances. This meant receiving the optical signal, cleaning and amplifying it electronically, and then retransmitting it over the...kelonlauhttp://kelonlau.mee.nu//the_fundamentals_of_edfasFiber Optic Adapter You Must Know2015-02-11T06:29:35ZFiber Optic Adapters,couplers,mating sleeves, FC, SC, ST, LC, UPC,APC,MT-RJ, MU, E2000,female to female,hybrid,female to male, hybrid fiber optic adapters,multimode fiber connectors, multimode fiber optic adapters,simplex,duplex, quad fiber adapters.

Previously, to solve this issue, a repeater or a regenerator would be used. A regenerator also called optical-electrical-optical (OEO) device since it converts the optical signal to an electrical signal, processes this signal (re-amplify, reshape and retime) and then converts back to an optical signal so that the signal can then cover longer distances. The introduction of optical amplifiers in the 1990s, especially the EDFA (Erbium doped fiber amplifier) conquered the regenerator technology and opened doors to the WDM technology. The EDFAOptical Amplifiers, unlike the...kelonlauhttp://kelonlau.mee.nu//bacic_edfa-erbium_doped_fiber_amplifier_designFiber Optic Splitter From Fiberstore 2015-01-21T08:11:06ZFiber optic splitter, also named beam splitter, is based on a quartz substrate of integrated waveguide optical power distribution device, the same as coaxial cable transmission system, The optical network system also needs to be an optical signal coupled to the branch distribution, which requires thepassive optical splitter, Is one of the most important passive devices in the optical fiber link, is optical fiber tandem device with many input terminals and many output terminals, Especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH etc.) to connect the MDF and the terminal equipment and to achieve the branching...kelonlauhttp://kelonlau.mee.nu//fiber_optic_splitter_from_fiberstore_Erbium Doped Fiber Amplifier Technology2015-01-19T10:00:42ZAt the heart of EDFA technology is the Erbium Doped Fiber (EDF), which is a conventional Silica fiber doped with Erbium. When the Erbium is illuminated with light energy at a suitable wavelength (either 980nm or 1480nm) it is excited to a long lifetime intermediate state (see Figure 1), following which it decays back to the ground state by emitting light within the 1525-1565 nm band. If light energy already exist within the 1525-1565nm band, for example due to a signal channel passing through the EDF, then this stimulates the decay process (so called stimulated emission), resulting in additional light...kelonlauhttp://kelonlau.mee.nu//erbium_doped_fiber_amplifier_technologyThe More and More Mature Fiber Optic Cables Transmission Technology2015-01-06T06:41:00ZFiber optic media are any network transmission media that generally use glass, or plastic fiber in some special cases, to transmit network data in the form of light pulses. Within the last decade, optical fiber has become an increasingly popular type of network transmission media as the need for higher bandwidth and longer spans continues. Fiber optic technology is different in its operation than standard copper media because the transmissions are "digital†light pulses instead of electrical voltage transitions. Very simply, fiber optic transmissions encode the ones and zeroes of a digital network transmission by turning on and off the...kelonlauhttp://kelonlau.mee.nu//the_more_and_more_mature_fiber_optic_cables_transmission_technologyTesting Fiber Optic Splitters Or Other Passive Devices2015-01-05T03:47:10ZA fiber optic splitter is a device that splits the fiber optic light into several parts by a certain ratio. For example, when a beam of fiber optic light transmitted from a 1X4 equal ratio splitter, it will be divided into 4-fiber optic light by equal ratio that is each beam is 1/4 or 25% of the original source one. A fiber optic splitter is different from WDM. WDM can divide the different wavelength fiber optic light into different channels. fiber optic splitter divide the light power and send it to different channels.

Generally, Brillouin type amplifier is not used in optical communication. For a particular use, the decision has to be made about which amplifier to be used. The EDFA amplifier is used in-line amplifier on account of its compatibility. On the other hand, CATV amplifier will be a very good power amplifier because of its high saturation. EDFAs and conventional lasers, achieve gain by pumping atoms into a high energy state. This allows the atoms to release their energy when a photon of a suitable wavelength passes nearby.

Figure 7.4 shows a common way to implement such a connector. Each fiber is placed in a ferrule whose function is to provide the mechanical support for the fiber and hold it in place tightly. The ferrule can be made out of plastic, metal, or ceramic materials. The central piece of the connector itself is an alignment sleeve. The two ferrules are inserted in the sleeve, and proper alignment between the cores is ensured because of the tight mechanical...kelonlauhttp://kelonlau.mee.nu//connectorized_couplings
