2010 Edition, September 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Uncooled 25-Gb/s transmission of a 1.3-µm surface-emitting laser is demonstrated. A fabricated laser, which consists of an InGaAlAs-MQW DFB active stripe and surface-mountable structure,...

(>2 km) transmission at 2.5 Gbit/s
1999 Edition, Volume 1, January 1, 1999 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The impact of the 1.3-/spl mu/m Fabry-Perot laser spectrum width on the maximum transmission length is investigated theoretically, and 15-km transmission at 2.5 Gbit/s was demonstrated by using a strained MQW FP laser.

Chaotic optical communication over 1000 km transmission by coherent detection
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Chaotic optical communication was originally proposed to provide high-level physical layer encryption. For high-speed and long-distance transmission, chaotic signal is very sensitive to channel impairments such as dispersion and Kerr fiber nonlinearity. In the traditional chaotic optical...

280-Gb/s 320-km transmission of polarization-division multiplexed QAM-PAM with stokes vector receiver
2017 Edition, March 1, 2017 - Optical Society (The) (OSA)

We propose a novel three-dimensional modulation scheme on Stokes space for metro and regional optical transmissions. Based on this scheme, 320-km transmission of 280-Gb/s 160AM-PAM2 signals using a Stokes vector receiver is experimentally...

Uncooled 43-Gb/s InGaAlAs Light Source for 10-km Transmission
2011 Edition, Volume 23, April 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A 1.3-μm-range uncooled electroabsorption/distributed-feedback (EA/DFB) laser was demonstrated. Incorporating an InGaAlAs multiple quantum well (MQW) modulator, a low-capacitance structure, and butt-joint integration, this laser successfully demonstrated...

2015 Edition, September 1, 2015 - Viajes el Corte Ingles, VECISA

A 112-Gb/s PAM4 transmitter module which integrates InP DFB and EAM demonstrated for the first time 2 km transmission with only 3-taps equalizer due to 50 GHz bandwidth, >13 dB extinction ratio and 1.5 mW output power.

Comparison of VSB PAM4 and OOK Signal in an EML-Based 80-km Transmission System
2017 Edition, Volume 29, December 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A comparison between 51.84-Gb/s vestigial sideband 4-level pulse amplitude modulation (PAM4) and ON-OFF keying (OOK) signals at a transmission distance of 80 km is experimentally demonstrated for the first time. An electro-absorption modulated...

28-Gbit/s 80-km transmission using SOA-assisted extended-reach EADFB laser (AXEL)
2017 Edition, March 1, 2017 - Optical Society (The) (OSA)

We fabricated 1.3-pm AXELs to extend the transmission distance with 28-Gbit/s-NRZ signal. SOA-assisted gain is effective in increasing the average output power. We successfully demonstrated 80-km transmission with an APD-ROSA.

56-Gbaud PDM-QPSK: coherent detection and 2,500-km transmission
2009 Edition, Volume 2009-Supplement, September 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A 56-Gbaud (224-Gb/s line rate) polarization-division multiplexed quadrature phase shift keyed (PDM-QPSK) signal is transmitted over 2,500 km (32 × 80 km) of fiber and is coherently detected using two 80-GSamples/s oscilloscopes with off-line signal...

Modulator integrated DFB lasers with more than 600-km transmission capability at 2.5 Gb/s
1997 Edition, Volume 9, October 1, 1997 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The modulator integrated DFB laser diodes with more than 600-km transmission capability over normal fiber at 2.5 Gb/s, have been reproducibly achieved. The longest transmission length obtained in the experiment is as long as 800 km.
