چکیده
A cryogenic packaged vertical-cavity-surface-emitting laser (VCSEL) with microwave input and coupled OM4 fiber for optical output was developed demonstrated operation from 295 to 2.9 K. Record K data links of 100 Gbps pulsed amplitude modulation 4-level have been an energy per bit ∼153.4 fJ/bit when TDECQ = 3.79 dB. The energy/bit is limited by the link path bandwidth resulted cable loss VCSEL can be further improved. Thus, proven a viable solution communication computing.

35.2 Gbps 8-PAM transmission over 100 m of MMF using an 850 nm VCSEL
We report experimental demonstration of 8-PAM transmission using an 850 nm VCSEL and 100 m of OM4-type MMF. The 8-level driving signal was generated using a 3-bit DAC, the error rates were measured in real time using a conventional error analyzer. Maximum uncoded bit rate was 37.5 Gbps, which corresponds to 35.2 Gbps with 7% FEC overhead.

The demand for more broadband services such as video on demand, social networking, cloud/grid computing...is expected to grow up. To support and provide these services to the users, the capacity in access network must increase, driving thus data rate increase in metro/core transport network. In the past, the demand for more capacity in WDM long-haul transport network has been enabled by increas...

We present high speed real time, error free 4-PAM transmission for short range optical links based on a VCSEL operating at 850 nm, a multimode fibre and a simple intensity detector. Transmission speeds of 25 Gbps and 30 Gbps are demonstrated, and the maximum fibre reaches were 300 m and 200 m, respectively. The 4-PAM is also compared with OOK transmission at 25 Gbps, and we find that at this bi...
متن کاملChallenges in Gbps Wireless Optical Transmission
In this paper, the link budget of Gbps wireless infrared indoor communication is analysed. We particularly focus on the receiver sensitivity and identify the most suitable wavelengths range. We show that an optical receiver operating at 1 Gbps will hardly achieve the shot noise limit, which is determined by the received amount of background light. Regarding the link budget, we present two case ...
