A Ball lens is also often used. The light propagation, along a waveguide can be described in terms of a set of guided electromagnetic waves, called as modesof the waveguide. It is found that even when the cladding has a slightly higher refractive index, the light passing down the core undergoes total internal reflection, and it is thereby contained within the core of the optical … It may be a semiconductor laser or an LED.

Pulse broadening. It has a central core in which the light is guided, embedded in an outer cladding of slightly lower refractive index Fig. Designations used by companies to distinguish their products are often claimed as trademarks.

Fundamentals of Coherent Optical Fiber Communications Abstract: The recently developed digital coherent receiver enables us to employ a variety of spectrally efficient modulation formats such as M-ary phase-shift keying and quadrature-amplitude modulation. Moreover, in the digital domain, we can equalize all linear transmission impairments such as group-velocity dispersion and polarization-mode dispersion of transmission fibers, because coherent detection preserves the phase information of the optical signal.

Она закрыла лицо руками. Дэвид не мог прийти в. - Но, Сьюзан… я думал… - Он взял ее за дрожащие плечи и повернул к. И тогда он увидел, что Сьюзан вовсе не плакала. - Я не выйду за тебя замуж! - Она расхохоталась и стукнула его подушкой.  - До тех пор, пока ты не объяснишь, что такое без воска. Ты сводишь меня с ума.

Стратмор вытащил из-под ремня мобильник и набрал номер. - Ты блефуешь, Грег. - Вы этого не сделаете! - крикнул Хейл.  - Я все расскажу. Я разрушу все ваши планы. Вы близки к осуществлению своей заветной мечты - до этого остается всего несколько часов.

Мы должны вырубить питание главного банка данных. - Это невозможно, - сказал директор.  - Вы представляете, каковы будут последствия. Джабба отлично знал, что директор прав. Более трех тысяч узлов Независимой цифровой сети связывают весь мир с базой данных агентства.

Росио покачала головой: - Это. Но вам ее не найти. Севилья - город большой и очень обманчивый.

Ради всего святого, зачем вы это сделали. Чтобы скрыть свою маленькую тайну.

Он схватился руками за боковые стороны проема и, одним движением вбросив свое тело внутрь, тяжело рухнул на лестницу. Халохот услышал, как где-то ниже тело Беккера упало на каменные ступеньки, и бросился вниз, сжимая в руке пистолет. В поле его зрения попало окно. Здесь. Халохот приблизился к внешней стене и стал целиться .

Она пропустила эти слова через компьютер и поставила перед ним задачу переставить буквы в новую фразу. Выходила только абракадабра. Похоже, не один Танкадо умел создавать абсолютно стойкие шифры.

На другой стороне авениды Изабеллы он сразу же увидел клинику с изображенным на крыше обычным красным крестом на белом поле. С того момента как полицейский доставил сюда канадца, прошло уже несколько часов. Перелом запястья, разбитая голова - скорее всего ему оказали помощь и давно выписали. Беккер все же надеялся, что в клинике осталась какая-то регистрационная запись - название гостиницы, где остановился пациент, номер телефона, по которому его можно найти.
