Cómo comprar fibra convertidor de medios

Un factor importante en la contratación actual, las empresas consideran que el precio, especialmente las pequeñas y medianas empresas y la oficina SOHO. Creemos que unos pocos cientos de dólares de productos suficientes para satisfacer las necesidades generales de las empresas, con excepción de las industrias especiales, como las telecomunicaciones, militar, etc. Por supuesto, además del precio, sino que también debe considerar el producto con el que rodea la compatibilidad con el medio ambiente y el producto en sí, la estabilidad, fiabilidad, de lo contrario el precio es bajo, comprar también sin uso. Con el fin de ser capaz de elegir un buen producto, ya los puntos de adquisición son los siguientes:
(1) si se puede admitir full-duplex y half duplex, ya que algunos chips del mercado, utilizando el entorno de dúplex completo, no pueden apoyar half-duplex, conectado a otras marcas de interruptores (interruptor de N-Way) o hub (HUB), utilizando el modo half-duplex, se traducirá en una colisión grave y la pérdida de paquetes.
(2) si se hace la prueba de conexión con otros conectores de fibra óptica, actualmente disponible de fibra convertidor de los medios de comunicación cada vez más como la compatibilidad mutua de las diferentes marcas del convertidor de fibra no se hace antes de la prueba también ha perdido el tiempo de transmisión de paquetes es demasiado largo fenómeno, de repente rápido repente lento.
(3) si se tiene que evitar la pérdida de los dispositivos de seguridad, muchos fabricantes en la producción de fibra de convertidor de medio de comunicación, con el fin de reducir los costos, a menudo utilizando el modo de transferencia de datos del registro, la mayor desventaja de esta manera, la inestabilidad de la transmisión de datos, lo que resulta en pérdida de paquetes, y la mejor manera es usar un diseño de circuito buffer, seguro para evitar la pérdida de datos.
(4) si el producto tiene que hacer pruebas de temperatura, fibra convertidor de los medios utilizados para producir fiebre alta, junto con el entorno de la instalación es generalmente al aire libre, por lo que la temperatura es demasiado alta (no superior a 50 ° C), fibra convertidor de medios si el funcionamiento normal, los usuarios son factores muy importantes a tener en cuenta! La temperatura máxima permisible es ¿cuánto? Esta muy digno de nuestra atención a las necesidades de equipamiento de larga duración.
(5) si el producto cumple con los estándares IEEE802.3 Tal como convertidor de fibra cumplan con IEEE802.3 estándar, si usted no cumple con la norma, entonces, ciertamente, no habrá problemas de compatibilidad.
(6) para evaluar el servicio técnico del fabricante, imagina si su equipo se rompe, la fábrica de unos días no resuelven el problema, su pérdida es cuánto. Por lo tanto, a fin de que el servicio post-venta de primera respuesta oportuna, se recomienda seleccionar la región cuenta con excelente resistencia, la fuerza técnica, compañía profesional de buena reputación. Sólo los más experimentados ingenieros técnicos profesionales para solucionar problemas y detectar las fallas de las herramientas más avanzadas
(7) Cuando usted compra observar cuidadosamente el aspecto del producto, eche un vistazo a la cáscara de la fibra del módulo sea antiguo, sea brillante o si los signos de desgaste. En el mercado hoy en día con el fin de obtener grandes ganancias, muchos fabricantes utilizan en los medios de la fibra convertidores, interruptores ópticos y otros equipos utilizados o viejo módulo de fibra óptica, el uso de estos productos de módulos de fibra óptica de segunda mano, hizo que una gran cantidad de oculto transmisión de la red, tales como: módulo de contaminación de la fibra óptica de la transmisión de la señal debe ser afectada, la disminución de la calidad de la transmisión. Calidad de transmisión, en consecuencia reduce sensibilidad de recepción también puede causar fenómeno de pérdida de datos. Junto con el uso de transceptor de fibra utilizado, será descontado en la vida de fallo de los componentes, etc, en cualquier momento.

What Is The Advantages of Fiber Optic Cables

Optical fibers are strands of super pure flexible glass used in telecommunications and they could be as thin as human hair. These fine chain transit digital signals in the form of light. A two layer plastic coating is presented in each fiber so that they reflect light back to the core and move it forward without too much loss. There are many such fiber is arranged in the package a set of functions and these package called optical fiber cable. A cable buffer coating again final outer for additional protection from water and other damaging agents.

Fiber optic communication in mobile through two main types of fiber optic cable. Laser light through the single mode fiber optic cable transmission signal and the multimode cable, LEDs or light-emitting diodes do this job. Multimode cable thicker, heavier than single-mode cable. Basic principle of total internal reflection works to transmit light signals in optical fiber communication from origin to destination.

In addition to the cable itself, other parts are very basic component system. A "transmitter" is a device generates coded light signal through the cable. When the optical signals in mobile distance, they will become weak, now an "optic regenerator" they copy the complete signal and regeneration stream connected to the full in the future. A shorter version of the optical cable may not need an optic nerve regeneration. To reach its destination, an "optical receiver" receives coded light-signals and decodes them into a readable form.

Apart from telecommunications, the technology of optical fiber communication comes handy in Internet signals, medical imaging, and inspecting plumbing and sewer lines and even in digital television connections. Optical fiber cables are more helpful than conventional copper cables.

What's the advantages of fiber optic cables?

Cost effective

Fiber optic cables are more cost-effective than copper wire. By replacing copper with optical fibers, the service providers as well as customers save a lot of money. The higher carrying capacity of optical fibers over copper wire is another advantage. Transmissions of more signals at a time without much interference is of great help to the customers.

Flexible, lighter and less bulky

In most urban places, there is an acute shortage of space. This limited available space is shared among subways, sewer lines and power wires. Being lighter and less bulky, they can fit in crowded and smaller places, it is easy to transport them to different places of installation. Flexibility is their gifted advantage, this very character makes them move through every corners quite easily.

Lesser degradation of signals

Fiber optic cable can preserve signal strength over a remote compared than traditional electric wire. Optical signal transmission through the cable will not interfere with each other so that you receive signals, easier and more clear understanding.

Use less power

Signal generator is used for optical fiber communication use less energy and thus save considerable amount of money on power. Since the signals are digital in nature, the computer networks pick them easily.

Safe

Since optical fibes use light for signal transmissions instead of electricity, incidences of the hazards and electric shocks are ruled out. This makes them safer than conventional wires.

Such being the amazing capabilities of bulk fiber optic cable, the new possibilities in the field optical fiber communication are always on the rise.

OTN + PTN Should Pay Attention To The Problem of Joint Networking

OTN and PTN as a new form of the technology, but also do not have a long period of large-scale networking experience, often in actual networking both influence each other, complement each other, therefore, to consider using OTN+PTN joint networking mode more often, between the restrictions existing at all levels of the technology itself, but also the OTN, PTN implicated, need careful consideration in the planning and construction of the unified deployment.
1. Equipment Interoperability Issues
PTN and OTN are the emerging technology of DWDM, OTN inherited the bulk transfer function at the same time, the introduction of flexible scheduling based on the wavelength, sub-wavelength features, its greatest feature is the use of a fully open system architecture, its hosted business the relationship between the client layer and the service layer, can be said to be innate transparent transmission platform. For OTN+PTN joint networking is no exception, OTN as a transparent delivery platform for convergence layer and access the service layer and the client layer, independent of each other, very similar in the mass deployment of WDM and SDH network relationships. OTN carrying the PTN, like WDM carrying SDH.
2. Precise time synchronization problem
Time synchronization is a new demand for 3G mobile standard, especially in terms of China's three major carriers, not an accurate time synchronization network, in the construction of transmission network, with particular attention to the precise time synchronization problems. In view of the technical system from terrestrial transmission time synchronization. As a result of the mode of OTN+PTN joint networking the OTN equipment deployment in the core network backbone layer the PTN equipment deployment in the aggregation and access layer, the time source first deployed in the side of the local network core equipment room RNC, RNC first time synchronization information passed to the core layer PTN core layer PTN, passed to the core layer of the OTN equipment, the OTN equipment then in turn transmitted to the other layer PTN equipment for precise time synchronization of the whole network. Currently the 1588v2 protocol has become PTN PTN carrying a basic technology, mainstream manufacturers have been a lot of testing. If using OTN+PTN joint networking mode, the requirements OTN supports the precise time transfer function, this is a new research topic has been very clear and realistic demand, but the maturity of the technology apparently has not yet reached the time with PTN sendstage synchronization par. From mainstream manufacturers the OTN send time synchronization technology point of view, the current implementations, there are three: the transparent transmission scheme 1 GE/10 GE, OSC with overhead transfer program the outer transfer programs, as well as the OTN band, the actual networking based on demand, as well as send the advantages and disadvantages of different options to choose or combination of applications.
3. The Protection Issues
Network safe at all, regardless of the OTN, PTN network, need to consider unified network protection. OTN equipment deployed in the core network backbone layer the PTN equipment deployment in the aggregation and access layer, between all levels often requires a large number of service interworking and scheduling, protection for the business needs of the end-to-end or section.
4. Interface Issues
In the metropolitan area network and local area network, often data services occupy the mainstream of the business, in particular, GE, 10 GE interface consistency should be noted that in the interface in the network, and 10 GE signal, for example, serveral 10 GE LAN signal OTN network mapping ITU-T defined G.709 and G.sup43, the standard GFP-F G.sup436.2, ODU2e way G.709.1.4 and expansion GFP-F/OPU2 way G.709 17.3.1, should maintain the consistency of the package, and mapped signal.
5. Network Management Issues
PTN and OTN mainstream manufacturers in the industry can achieve a total network management platform to facilitate the maintenance of the network, in general, from the point of view of the network management. Than in PTN and OTN joint-networking mode, OTN often located in the core layer, PTN position in the aggregation, service interworking and scheduling between the access layer, at all levels, so wheter it is in the opening of business, or in the network pipe maintenance needs, and have put forward higher requirements.
6. Maintenance of The Network
In the metropolitan area and the local network, the device level more complex networking, brought no small difficulty to the network fault location. When networking joint OTN+PTN, PTN and OTN technology inherited SDHhierarchical OAM management mechanism, business package, there will be a rich overhead monitor, the OAM PTN including customer layer OAM, channel layer OAM, channel layer OAM and segment layer OAM, OTN support 6 levels of TCM, SM, PM, etc., each layer will provide fault and performance, so as to realize the OAM in different level real-time, accurate fault location function.
