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.

Sopto CWDM SFP+ transceiver is small form factor pluggable module for serial optical data communications such as IEEE 802.3ae 10GBASE-LR/LW/ER/ZR by using dual fier. It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available. These CWDM SFP+ modules are designed for single mode fiber and operate at a nominal wavelength of CWDM wavelength.   There are 18 center wavelengths available from 1270nm to 1610nm, with each step 20nm. A guaranteed minimum optical link budget of 14dB is offered. The transmitter section uses a CWDM multiple quantum well DFB/EML laser and is a class 1 laser compliant according to International Safety Standard

This module code SPT-SFP+LR SFP+ 10G-LR 1310nm 10KM Supports DDM options

  Sopto provides 10G fiber transceivers, SFP+, XFP, XENPAK and X2 , all of them have Digital diagnostic monitoring (DDM) function, and it provides a user with critical information concerning the status of the transmitted and received signals.     DDM gives the end user the ability to monitor real-time parameters of the 10G SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

The advantages of the 40Gbits transmission system

  Based on the key technology and the characteristics of itself, the 40Gbit/s system has the following advantages :     (1) It can be more efficient to use transmission bandwidth, and the spectrum efficiency is higher.     (2) The 40Gbit/s system reduces the complexity and cost of the OAM and the number of spare parts.     Especially in the network Metropolitan area backbone, the schedulability and integration of 40Gbit/s system is far better than 4x10G system because that can save area of room, reduce the device stack and improve the management ability and operation ability of bandwidth of the single node equipment.     (3) The cost of every bit is
