Future optical networks will consist of photonic switches, optical crossconnects, and routers that may be configured with links consisting of a number of user bearer channels and an associated control channel. This paper describes a new link management protocol, called LMP, which runs between neighboring nodes and will be used for both link provisioning and fault isolation. A unique feature of ...

Optical communication technology has been developed rapidly to achieve larger transmission capacity and longer transmission distance. In this paper we demonstrated optical time division multiplexing extended reach 10 Gb/s passive optical network (PON) architecture of 100 km length with 1:128 split ratio. The 100 km system is enabled by the use of corning nexcore fiber and corning SMF-28 fiber w...

To transfer high speed data streams, a line of sight (LOS) broadband free space optical (FSO) communication link has been designed between two private local LANs located at an aerial distance of about 2 km. A laser diode (LD) – avalanche photodiode (APD) combination operating at 1550nm is used to work as an optical trans-receiver system while an Erbium-doped optical amplifier (EDFA) is used to ...

Sub-fs X-ray pulse generation in kilometre-scale FEL facilities will require sub-fs long-term timing stability between optical sources over kilometer distances. We present here key developments towards a completely fiber-coupled, pulsed optical timing distribution system capable of delivering such stability. First, we developed a novel 1.2-km dispersion-compensated, polarizationmaintaining fibe...

Many properties of an optically interconnected system can be improved through the use of a modelocked laser. The short pulse duration, high peak power, wide spectral bandwidth, and low timing jitter of such a laser lead to these benefits. Timing advantages include simplified synchronization across large chip areas, receiver latency reduction, and data resynchronization. Lower power dissipation ...

An optical link can provide an interface channel for the focal-plane array that is immune to electromagnetic interfer ence (EMI) and can lower the heatload on the dewar. Our approach involves the use offiber-optics and an on$ocal.plane optical modulator to provide an interface to the focal-plane array (FPA). The EPA drives the modulator with an electrical signal. We evaluated specially fabricat...

The optical signals degrade as travel down the optical link due to the optical fiber properties such as chromatic dispersion, polarization mode dispersion, polarization dependent loss, polarization dependent gain and various fiber nonlinear effects, which are considered as limitations in the high-speed, lang-haul fiber communication systems. Where chromatic dispersion causes different wavelengt...
