What is the difference between SFP+ and SFP
The difference between SFP+ and SFP. The pinout of SFP and SFP+ connectors are identical. However, SFP is data rate of 6Gb/s, whereas SFP+ is designed for 10Gb/s.
The SFP receptacles and plugs are not as well impedance matched as SFP+ receptacles and plugs.
Also SFP+ cable is designed for 10Gb/s whereas SFP cable may not be able to satisfactorily transmit that rate.
The SCFF fiber optic transceiver compared with the existing SFP+, this fiber optical transceiver saves a lot of inner substrate surface, and will not impair the performance or the line board density. The transceiver has a small size, which is developed by the structure of the SFP+ industry standard by mechanical means. The power dissipation of SCFF fiber optical transceiver is less than 1 watt. With the compact and simple size, it is very suitable for enterprise storage hardware, NIC, HBA, HCA as well as industry, instrumentation and medical applications.
Since the multiple ONU devices share the same optical fiber medium to communicate with the OLT in PON system, it is mainly to solve the media sharing problems between different ONU. The main way to solve this problem includes the time division multiplexing (TDM)/ multiple access technology, wavelength division multiplexing (WDM) and orthogonal frequency division multiplexing (OFDM). Therefore, the major technology can be divided into TDM-PON, WDM-PON and OFDM-PON. At present, both EPON and GPON adopt the TDM-PON technology. And the application of EPON and GEPON become wider and the technologies are mature.
The 18 channels Coarse Wavelength Division Multiplexer (CWDM). Sopto is a manufacturer specializing in the production of a full range of wavelength division multiplexer which includes the coarse wavelength division multiplexer (CWDM) and the dense wavelength division multiplexer (DWDM). The wavelength division multiplexer (WDM) has become the solution to the shortage and expansion of long-distance signal transmission cable. The wavelength division multiplexer (WDM) is widely used in Gigabit & 10G Ethernet, SDH / SONET, ATM, ESCON, FTTx and CATV system. The wavelength division multiplexer (WDM) produced by Sopto is used the thin-film filter technology. It has the
