beam

 [bēm]
a unidirectional, or approximately unidirectional, emission of electromagnetic radiation or particles.
useful beam in radiology, that part of the primary radiation that is permitted to emerge from the tubehead assembly of an x-ray machine, as limited by the aperture or port and accessory collimating devices.
beam splitter a device that reflects light from the output phosphor of an image intensifier to a photographic recording. Called also image distributor.

beam splitter

Radiation oncology
A device that divides a beam of electromagnetic radiation into 2 or more distinct beams.
 
Telemedicine
A device that divides the image beam of a clinical examining scope so the physician has the choice of looking at the image on a video monitor or directly through the scope.

beam splitter 

An optical system which separates an incident beam of light into two beams of lesser intensity, one reflected and the other transmitted, e.g. a semi-silvered mirror. Some beam splitters are made of birefringent material, which splits the incident light beam into oppositely polarized beams. They are called polarizing beam splitters. Example: Wollaston prism.

Specifically, [P.sub.cost], [O.sub.cost], [D.sub.cost], and [L.sub.cost] represent the cost of the passive optical splitters, the optical line terminal, the antenna units, and the optical fiber, respectively.
Failures in optical splitter and FF are rated higher than DF, ONU, and GW as their failures will have impact on relatively more MC.
FiOS is a passive optical network (PON) that uses a passive optical splitter to distribute data from the nearby optical line terminal (OLT) to up to 32 residential and small business premises.
Economically extending FTTx deployments, the cabinet provides a complete interconnect environment from the feeder network through the passive optical splitter to the distribution network, enabling carriers to cost-effectively launch PON services into new markets.
As mentioned in the previous section, the PON distribution is done by using an optical splitter. The function of this component is to distribute the optical signal from the CO to the subscribers.

The fiber is split at a passive optical splitter, which can be directed to up to 32 ONTs.
Motorola's Optical Splitter based networking solution replaces the existing LAN connections as well as traditional network switches with an individual high capacity cable; transmitting information to connect the end user directly with the data centre by sending light signals through an optical fibre.
In traditional Time-Division Multiplexed Passive Optical Network (TDMPON), the number of ONUs is limited by optical splitter attenuation on single wavelength, but using WDM-PON technology we can provide 16, 32, 64 or even more wavelengths in optical access network [2, 4].
