PMC metro OTN help China achieve 400G and OTN switching technology

Recently, PMC has released its newest DIGI-G4-- latest generation of OTN chip. PMC Chinese R & D Center for Communication Products Division Director Zhang Tianyu introduced to, DIGI-G4 is the first industry's highest density single-chip, can support 400G. Further integration of a large number of equipment manufacturers put the device on the board, resulting in a large power cost increases, while DIGI-G4 to peripheral devices incorporate internal, so that each port 100G power by 50%.

Interview, PMC DIGI-G4 product line manager Kevin representation, PMC developed this chip is completely respond to the needs of the market, that the rapid growth of bandwidth, the bandwidth will double every two years, which in the world are Such a trend. On the other hand, 100G become the standard has become a trend, this standard mainly in the backbone network, including China Mobile, China Telecom is largely concentrated in such a network backbone, certainly in terms of the operators to the metro, these bandwidth from the metro to the demand increase network access, metro bottleneck is additionally backbone.

In addition to bandwidth requirements, is the data center needs. Kevin stressed that large scale data centers, they are to complete the interconnection between the data centers. DIGI-G4 chip design at the beginning of this just like Google, AMAZON have conducted technical exchanges, they are particularly urgent need is encrypted. Light layer of encryption is not enough, mainly because we have to have encryption in the business layer, we DIGI-G4 chip encryption can be done in the 100G OTN, not only in 100G encryption, I can rate the operational level in my son's entire 100G You can be encrypted.

Zhang Tianyu said, OTN switching is actually OTN electrical cross concept think back 45 years ago when the mainstream use in backbone OTN, or one of the technical support line, in fact, a few years ago that is electrically OTN Cross into the mainstream over the past few years, we can see that a carrier is a strategy they deploy the branch line from the previous one turned into OTN switching, China at the forefront, China's leading OTN deployment in the world, We see in the world is a very clear trend in the world's top ten operators have nine full deployment of OTN electrical cross-based network, see the full flexibility of this technology to operators on services.

Currently, the chip supplier in terms of providing light to the equipment manufacturers a chip is not enough, cost pressures down the pressure from the operator level, for equipment operators in terms of R & D investment is controlled, previously invested heavily in software research and development team We do such a transmission device is unrealistic, so a lot depends on chip manufacturers, can have a complete package in the release of the chip at the same time available to them so that they can be completed within a short period of their development.

Zhang Tianyu finally said, PMC continues to invest in software, accounting for the company's software engineers than hardware engineers now, we offer a very complete package, and after the actual deployment verification, to reduce secondary research equipment manufacturers.

2016 China Telecom Solutions XG-PON1 interoperability

Currently, China Mobile added, broadband access market is highly competitive. China Telecom and China Unicom have copper resources are not willing to discard, so broadband network construction development should consider both asset protection. China Mobile is no copper "burden", and funded with strong competitiveness. Faced with the impact of China Mobile, China Telecom and China Unicom efforts to strengthen the construction of FTTH.

As the main force of China Telecom FTTH in the past few years, we have begun a gradual transition from the access technology G / EPON to 10G-EPON. Recent China Telecom's 2015 Central Purchasing PON equipment, including one million 10G EPON port, close to the G / EPON port level.

XG-PON is the next generation of GPON evolution of technology. Judgment based on practical needs and technology maturity, FSAN NG-PON evolution of the definition of planning is divided into two stages: XG-PON1 and NG-PON2. XG-PON1 medium-term evolution of PON, focusing on the study of both existing GPON ODN laying next generation standards.

10G EPON interoperability has been resolved, the current focus is to reduce equipment costs. XG-PON1 current focus is to promote interoperability, China Telecom will launch in the second half of 2015, 2016, respectively, and interoperability testing different vendors OLT ONU (SFU / HGU) devices, target solve interoperability in 2016, the scale of 2017 Commercial technical preparedness.

For China Telecom, XG-PON is insurmountable stage. Within three years, is expected to TWDM PON (NG-PON2) in standard equipment maturity, cost, interoperability and other aspects not yet reached the large-scale commercial level. China Telecom will organize XG-PON interoperability testing, as the Point XG-PON technology matures.
