Attenuation reduction of the signal magnitude or loss, caused by absorption and scattering Values are normally expressed in decibels (dB) Attenuator a passive device for reducing the amplitude of a signal without distorting the waveform Bidirectional a device, which operates in both directions Broadband Device optical broadband devices cover a wide range of wavelengths Center […]
Insertion loss tests are primarily used to test FTTx PONs (Passive Optical network) during installation. Insertion loss testing may be performed on individual fiber segments as they’re installed (e.g. test feeder fiber from Central Office (CO) to Fiber Distribution Hub (FDH), test distribution fiber from FDH to AP, or test drop fiber from AP to […]
PON architectures for FTTH deployments are currently based on passive optical splitters to distribute the bandwidth to each customer using fiber splitters providing ratios ranging up to 1:64 or even 1:128. The physical PON FTTH architecture typically supports the Ethernet protocol. PON network feeds a variety of optical network terminations (ONTs) or optical network units […]
Overview A new White Paper by the FTTH Council Market Intelligence Committee finds European FTTH deployment cost estimates are highly accurate. That makes investing in fibre highly attractive. To determine whether the FTTH cost estimates used in European projects accurately represent the actual costs, the FTTH Council approached a wide selection of parties involved in […]
On a transmission network, one cause of insertion loss on a fiber link is macro bending. This is commonly caused by tight installation or handling. As Fiber-to-the-Home (FTTH) networks lead to a significant increase of fiber installation in the last mile, the space constraints become increasingly stringent. This is driving the need for distributions hubs […]
The LC connector (short for Lucent Connector, Little Connector, or Local Connector), It features a 1.25mm Zirconia ferrule in a small form factor (SFF) fibre optic connector housing with a snag free latch which gives an audible click upon engaging for reliable and high density connections. The LC connector complied with IEC 61754-20, it is […]
The SC connector (short for Subscriber Connector, square connector or Standard Connector) mianly used in Datacom and telecom; GPON; EPON; GBIC, It features a 2.5mm Zirconia Ceramic ferrule and a push/pull coupling mechanism for a fast and reliable connection. The SC connectors are available for single mode UPC with blue boots, for APC with green […]
HFC and FTTH networks differ in that HFC extends fiber to a node within a mile of the home or business, while FTTH extends fiber all the way to the home or business—typically terminating the fiber at a customer premises device, which then provides service to devices in the home over copper lines, coaxial cable, […]
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 […]
Not all FTTH networks are built the same. Since construction and outside plant account for the majority of total network costs, getting the architecture right has a major impact on the business case. The network architecture can also impact time-to-market, labor/training requirements, future upgradeability, network performance, and ultimately customer satisfaction. This paper provides an overview […]
