This paper demonstrates the coexistence of next generation PON (NG-PON) systems with legacy PON systems for CHT's network by commercial coexistence element (CEx). Because there are GPON and EPON in CHT's network, we will show the impact to legacy PON systems by using this commercial CEx and how we modify it.
We investigated the WDM-PON with low-cost, mass-production C-/ L-band SFP transceivers based on injection-locked FP-LDs, and designed video transfer player systems to perform the network traffic stress test.
The DWDM-PON transmission of coherently injection-locked WRC-FPLDs with ER (7.55 dB), SNR (7.6 dB) and Q factor (6.7) improved by 4.6%, 25.6% and 13.6% are demonstrated by enlarging AR coating reflectance from 0.5% to 1.2%.
The low pressure discharge law for coaxial filter based on gas discharge is presented in this paper. The law is demonstrated by classical theory. In order to validate the law, the 3-pole filters were designed, fabricated, and experimented. The practical measured data is presented showing good agreement with the analytical results.
Waste iron chippings and fly ash can be used to remove Cr(VI) in groundwater, lab expriments show that, without changing the pH of groundwater, the compoud mediator of waste-iron chippings + fly ash has better effects on wiping off the Cr(VI) in water than pure waste-iron chippings or fly ash. The disposal efficiency of the compound mediator can reach 97 percent. And the repetitive results of the...
We investigated the WDM-PON based on injection-locked FP-LDs and trial test was conducted in Chunghwa Telecommunication Laboratories. To demonstrate 1 Gb/s transmission, we design a multi-channel HD video transfer player system to perform the network traffic stress test.
In this paper we described the pilot trial of colorless WDM PON which has been developed in Chunghwa Telecom Telecommunication Laboratories. We demonstrated to access triple-play services via 1 Gbps per user.
Criterion on extinction ratio and overshooting level of smaller than 3dB and -5dB, respectively, for The SOA amplitude squeezed ASE data-stream to injection-lock the weak-resonant-cavity laser diode transmitter approaching BER<;;10-9 at 2.5 Gbit/s is reported.
With the system functions growing rich and the design growing difficulty, using ECU in-loop simulation as development platform of entire system can test the rationality and reliability of the control system design step by step in advance. Thus it greatly enhances the development quality of control system, reduces risk and increases the success rate of the design. Engine ECU hardware in-loop simulation...
