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 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
The core strategy of the "broadband China" is to enhance the user's home bandwidth to realize the real speed of the broadband. Judging from network deployment of the three operators, FTTH has gradually become a mainstream access mode. From a technical point of view, PON is the key technology to promote the broadband, which plays an important role in promoting the scale deployment of FTTH. Currently, EPON/GPON technology both can meet the demand of upgrade bandwidth. The GPON has been mature and can be large-scale commercial used in the international. Thanks to the fast downstream rate and split ratio, the domestic operators are accelerating to GPON
The SFP bidirectional fiber optic transceiver . The Sopto SPT-PB series of Bi-Di fiber optic transceivers is a signal converter to convert the electrical signal into the optical signal in the computer network. The biggest benefit of bidirectional fiber optic transceiver is to use only one (core) fiber to transmit and receive the optical signals simultaneously, which is less than the double fiber optical transceiver with a fiber so that it improves the amount of the existing fiber information transmission. The SPT-PB 155M/1.25G series of adaptive bidirectional fiber optical transceiver is fully compatible with the IEEE802.3 10BaseT, IEEE802.3u 100BaseTX and 100Base-FX
