Um olhar sobre a construção do cabo

ULTIMODE UNI-4MM-A OM3 é um cabo de fibra ótica universal para aplicações interiores e exteriores. Fibras multimodo OM3 estão contidos em tubo cheio de gel central. O gel no tubo é um tipo de revestimento protector das fibras ópticas, o qual absorve as tensões mecânicas e protege as fibras contra a factores ambientais. O fio de aramida que cobre o tubo central fornece proteção adicional contra danos mecânicos, inclusive riscos causados ​​por roedores.

ULTIMODE UNI-4MM-A OM3 cabo contém 4 fibras multimodo (J-Fibra). A identificação de cor das camadas de tampão em conformidade com o TIA-EIA-598-A padrão. O revestimento (revestimento) é feita de baixo fumo zero halogênio material retardador de chama (LSZH).

The multimode fibers used in the cable are OM3 50/125, currently the most popular multimode fibers that can be used for transmission in the I or II transmission window (850/1310 nm). The attenuation (IL) does not exceed 3.5 dB/km in the first transmission window, and 1.5 dB/km in the second transmission window. OM3 standard provides higher data throughput over greater distances than its predecessors. The transmission speed of 10 Gbps is possible at distances up to 550 m, and higher speeds, such as 40 Gbps and 100 Gbps can be reached at 100 meters (OM1 and OM2 standards do not allow for such fast rates).

Universal cables from ULTIMODE UNI series are gel-filled fiber optic cables intended for horizontal connections in buildings and outside buildings. Due to the small size and flexibility, the cables are ideal for installation in cable ducts. They are used in modern FTTH and FTTB systems, in server rooms, between buildings. Unlike external cables, universal cables can also be used inside buildings. This eliminates the need to create additional transitions, splices and cable distribution frames at the junction of the external and internal networks. Universal cables can be laid in cable ducts or even directly in trenches in the ground (in places where they are not exposed to direct mechanical damage).
