Introduction to Data Center Structured Cabling Guide
What is a Point-to-Point (P2P) Cabling System? The point-to-point (p2p) cabling system is constructed with direct connections. Patch cables are used to connect one device such as a router, switch, server or storage unit directly to another device. As the number of connections in a data center increases due to normal growth, a point-to-point cabling system is […]
что делает OTDR?
OTDR (Optical Time-Domain Reflectometer, оптический рефлектометр временной области) сертифицирует характеристики заново установленных оптических линий связи и определяет проблемы в уже существующих. OTDR измеряет характеристики оптического волокна, выводит в графическом виде отраженный оптический сигнал по всей длине линии и предоставляет таблицу параметров всех оптических событий, обнаруженных в линии связи. Измерительный процесс включают в себя измерение общего […]
Fiber to the Home (FTTH)
La fibra ottica è un mezzo di trasmissione ampiamente collaudato che garantisce un’elevata velocità di trasmissione dei dati. Nei prossimi anni diventerà sempre più importante per lo sviluppo delle reti locali, poiché i vecchi cavi in rame non basteranno per far fronte al crescente bisogno di maggiore larghezza di banda determinato dalle nuove applicazioni Internet, […]

Коннекторы серии FC SC ST LC
Коннекторы серии РС Способ подготовки торцевых поверхностей под названием “физический контакт” (Physically Contact – PC) предполагает фиксацию оптического волокна в алюминиевом наконечнике. Торец определенным образом полируется с целью достижения полного контакта торцевых поверхностей. Однако при полировке волокна происходят негативные изменения поверхностного торцевого слоя в инфракрасном диапазоне (так называемый “инфракрасный слой”), обусловленные механическими изменениями при полировке.
