corresponds to the SDH SFP standard speed signal

This allows to build up broadband WAN networks to tackle the increased traffic requirements. Ethernet ports and EoS mappers are directly integrated in this module.The standardization of interfaces determines the connectivity of different equipment from different manufacturers. SDH SFP 100MB/S system provides universal standards for network node interfaces, including standards at digital speeds, frame structure, the method of multiplexing line interfaces, monitoring and management. Therefore, SDH equipment from different manufacturers can easily be connected and installed in line that best demonstrates the system compatibility.Linear (optical) interfaces are using the universal standards. Linear OpEx signal only scrambled insert redundancy there. Standard scrambling - universal. Therefore, at the reception, and on the transmission should use standard scrambler and descrambler. Scrambling purpose - to make the probability of "1" bits and "0" bits is close to to facilitate the extraction of the clock signal line. Since only linear signal is scrambled, the linear velocity of the signal corresponds to the SDH SFP standard speed signal on the electrical interface SDH SFP. Thus, the power consumption of the optical transmission laser remains the same, however, reduced their heat (because it eliminates the possibility of following a large number of "1" in succession), which increases their service life. scrambled (English) - encrypted
