Network Equipment Selection – Considerations

In the early days of GPON service providers cared primarily about getting the service to work, and the easiest way to ensure this was to purchase an end-to-end GPON solution from a single vendor, who was responsible to make it work. Providers that used multiple vendors in their network divided their service area into different […]

Introduction to HFC Hybrid Fiber Coaxial Architecture

Cable technology is commonly called “hybrid fiber coaxial” or HFC. This is because most cable systems consist of fiber connections from the operator’s headend or hub facility (the cable counterpart of the telephone central office) to an optical “node” near the customer premises, and thereafter comprise coaxial cable to the premises. Cable operators have extended […]

Modelo de CAPEX en una ciudad o pueblo con 20.000 a

1. Diseño y consideraciones del proyecto La área urbana tiene las SMEs, o PYMEs, en una avenida principal con 10.000 abonados, de los cuales 8.000 son residencias en MDU. Cada MDU o edificio de departamentos en la área urbana posee 30 unidades habitacionales. Las áreas suburbana cuentan con viviendas unifamiliares (SFUs) y PYMEs, o SMEs. […]

¿QUÉ ES FIBRA HASTA EL HOGAR (FTTH)?

Empecemos con una definición simple; Fibra Hasta El Hogar (FTTH – Fiber To The Home) es la entrega de una señal de comunicación por medio de fibra óptica desde el equipo de conmutación del prestador de servicio hasta la casa o negocio del cliente, por lo tanto es un reemplazo de las redes de infraestructura […]

MTP MPO Trunk cables

On-site termination of an MPO/MTP® connector with 12, 24 or even up to 72 fibers is obviously no longer possible. In other words, if you use MPO connectors you also have to use trunk cables (Figure 11) delivered already cut to length and terminated. This approach requires greater care in planning but has a number […]

50um or 62.5um fiber for Data Center

In terms of physical properties, the difference between these two fiber types is the diameter of the core—the light-carrying region of the fiber. In 62.5/125 fiber, the core has a diameter of 62.5 microns and the cladding diameter is 125 microns. For 50/125, the core has a diameter of 50 microns with the same cladding […]

Copper or fiber? in data center

There are three strong reasons for the broad acceptance and rapid growth of twisted pair as the horizontal medium: low initial cost, the ability to deliver higher data rate LAN services and the flexibility to use one medium for all services. As speeds increase, copper-based LANs will require more complex and expensive electronics. Although, fiber’s […]

FTTA Fiber Handling Recommendations

Bend Radius When installing fiber cables, tower hands should pay attention to the minimum bend radius of the fiber. Standard fiber (complies with ITU-T recommendation G.652D) can maintain a minimum bend radius of five to 15 times the fiber cable diameter. Functionally, this corresponds to about three centimeters, or about one inch. Failure to observe […]

Repair and Testing for FTTA

Fusion vs. Mechanical Splicing Unfortunately, damage to fiber optic connectors is common in FTTA installations. If a fiber connector is damaged, either a whole new cable can be pulled or the damaged connector can be replaced. Fusion splicing is one method for attaching a pre-terminated fiber connector with a fiber stub (called a pigtail) to the broken […]

Fiber Optic Connectors – FTTA Fundamentals 3

Fiber optic cables are terminated with fiber optic connectors. The construction of the connector involves precise alignment of the end of the fiber with the end of the connector’s ceramic ferrule, which mates with the fiber receptacle. Fiber connectors can be UPC (ultra-physical contact) or APC (angle-physical contact). Generally, UPC is used for purely digital communication applications, such […]
