Description: Optical burst switching (OBS) is an optical networking technique that allows dynamic sub-wavelength switching of data. OBS is viewed as a compromise between the yet unfeasible full optical packet switching (OPS) and the mostly static optical circuit switching (OCS). It differs these paradigms because OBS control information is sent separately in a reserved optical channel and in advance of the data payload. These control signals can then be processed electronically to allow the timely setup of an optical light path to transport the soon-to-arrive payload. This is known as delayed reservation.-Optical burst switching (OBS) is an optical networking technique that allows dynamic sub-wavelength switching of data.

Description: Optical Burst Switching (OBS) network is seen as a promising solution as it directly transports Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks. OBS network uses a one-way resource reservation mechanism to set up the resources for each data burst transmission. Therefore, the performance of OBS networks depend on contention resolution strategies to reach acceptable levels for bandwidth utilization efficiency. This paper proposes the use of burst segmentation as a proactive contention resolution technique at ingress nodes of OBS network as well as reactive contention resolution policy at core nodes for reducing the probability of burst drop in the network in order to increase the performance of the network. -Optical Burst Switching (OBS) network is seen as a promising solution as it directly transports Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks.

Description: 自适应OFDM系统能根据信道估计得到信道的状态信息，自适应地调节发送端传输参数，从而提高系统的性能。其中OFDM是一种多载波调制技术，具有频谱利用率高、抗多径干扰、抗突发噪声差错等优点。
在VLC中引入自适应OFDM技术，可以提升系统的容量，提高传输质量，使系统具有更大灵活性，改善系统性能。在无线光通信领域对该技术的研究已成为个重要的方向。根据现有的研究人员所发表的文献，大多是基于基础性和理论性的研究，对可见光通信技术与自适应OFDM的研究甚少。(The adaptive OFDM system can obtain the channel state information according to the channel estimation, and adaptively adjust the transmission parameters of the transmitter, so as to improve the system performance. Among them, OFDM is a multi carrier modulation technology, which has the advantages of high spectrum utilization, anti multipath interference, anti burst noise, error and so on.
The introduction of adaptive OFDM technology in VLC, can improve the system capacity, improve the quality of transmission, the system has more flexibility, improve the performance of the system. In the field of wireless optical communication, the research of this technology has become an important direction. According to the literature published by existing researchers, most of them are based on basic and theoretical research, and few studies have been done on visible light communication technology and adaptive OFDM.)

Description: General Description
The GN25L95 is a combined burst mode laser driver and limiting post amplifier designed for fiber optic transceiver modules.
The GN25L95 features on-chip digital diagnostic monitoring and digital set-up. This enables a complete solution for SFP/SFF optical transceiver modules.
A fully compliant SFF-8472 digital diagnostic monitoring solution can be realised by connecting an external 8k EEPROM.
The GN25L95 features automatic mean power and automatic extinction ratio control functions for robust and reliable control of laser operating conditions over temperature.
Auto-ranging A/D converters with digitized monitoring, an internal temperature sensor and an on-chip DAC for controlling an external APD bias circuit are also included.
Consuming 90 mA from a 3.3 V supply the GN25L95 is packaged in a 4x4 mm QFN 28 pin RoHS package rated from -40 to +95 °C.
