The spring of GPON has come

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 Transceiver.


And regarding to the price, GPON terminal has been moved closer to EPON. The price of GPON terminal has dropped to the same level with the price of EPON. All the signs indicate that, the spring of GPON has arrived.

Class C+ GPON ONU SFP 1310nm Tx 1490nm Rx

SOPTO GPON transceiver is a high performance module, ZTE, Huawei and Alcatel compatible and designed for single fiber communications using a 1310nm or 1490nm burst-mode transmitter and a 1490nm or 1310nm continuous-mode receiver.

The classification of PON technology

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)

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

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.
