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.Show More
The weak-resonant-cavity Fabry-Perot laser diode (WRC-FPLD) injection-locked by three master sources with different degrees of coherence and directly modulated by two different digital modulation formats is demonstrated. The injection master coherence shows impact on noise, bandwidth, and modulation performances of the slave WRC-FPLD transmitter. Using the highly coherent master, the injection-loc...Show More
Long-cavity colorless laser diodes with different front-facet antireflection (AR) coatings are employed to perform the wavelength injection-locked ON–OFF-keying (OOK) data transmission. By changing front-facet reflectance of laser diode from 0.2% to 1.2%, the received OOK data enhance its Q factor by 6.3% and reduces its bit error rate (BER) by more than two orders of magnitude, which benefits fro...Show More
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.Show More
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%.Show More
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.Show More
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.Show More
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.Show More
We simulate the injection-locking performance of a 1% antireflection coated Fabry-Perot laser amplifier (AR-FPLA) and demonstrate the 2.5-Gbit/s DWDM-PON application with the directly modulated AR-FPLA based ONU transmitter under side-mode injection-locking condition. The effect of the AR-FPLA front-facet reflectivity on the injection locking range detuning and the Q-factor are interpreted from th...Show More
Quasi-color-free weak Fabry-Perot cavity laser diode with long cavity length is one alternative solution of the wavelength-division-multiplexed passive optical network (WDM-PON) transmitter with comparable broadband gain spectrum and greatly reduced noise figure as compared to typical reflective semiconductor optical amplifiers. In this paper, the amplified spontaneous emission injection-locked we...Show More

Amplified spontaneous emission (ASE) power and injection-locked mode number dependent frequency chirp and bit error rate (BER) responses of a weak-resonant-cavity Fabry-Perot laser diode (WRC-FPLD) transmitter are characterized.

Externally amplified spontaneous emission (ASE) injection-locking characteristics and optical data transmission performances of a TO-56 can-packaged Fabry-Perot laser diode (FPLD) with 1% front-facet reflectivity are investigated using a wavelength-division-multiplexing passive-optical network (WDM-PON) system configured by an array-waveguide grating (AWG) based MUX/DMUX filters with channel spaci...Show More
A novel anti-reflection coated Fabry-Perot laser amplifier under side-mode injection-locking for 2.5 Gbit/s DWDM-PON is demonstrated with SMSR >35 dB, Q-factor 9.2, locking range of 30nm, power penalty of -0.7dB, and BER of 10-12 at -23.7 dBm.Show More
