Crónicas de cableado


It seems like just yesterday we were talking about spring cleaning, and now we’re moving into the dog days of summer. And it’s hot.


In the 2014 version of ISO/IEC 14763-3, testing of optical fiber cabling, unidirectional testing for permanent links is required. In specific cases, bi-directional testing is required. However, ISO/IEC 14763-3 provides no information on how a bi-directional test should be done - this article explains how.

When Bi-Directional Testing is Required


Testing and characterizing a permanent link with an OTDR requires the measurement of connector attenuations A/B and fiber loss C. To make this measurement, a launch and tail cord are needed (see Figure 1).


Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it defines the direction that light signals travels through an optical fiber.

To properly send data via light signals, a fiber optic link’s transmit signal (Tx) at one end of the cable must match the corresponding receiver (Rx) at the other end.


Si bien puede parecer y sentirse como un latiguillo de fibra, los latiguillos de referencia de comprobación, o TRC por sus siglas, no son latiguillos. Existe algo diferente en estos latiguillos que se utilizan para certificar sistemas de cableado de fibra a los estándares ANSI/TIA, ISO/IEC e IEEE.


Recently we have been getting questions about how to determine if an SFP is working. I’m going to use SFP generically here to represent a multitude of the various optical modules that are available. The Fluke Networks fiber testers can be used to measure the light that is being put out by and SFP.


A estas alturas ya habrá escuchado hablar de las soluciones plug-and-play MPO de 8 fibras disponibles en el mercado, las cuales son ideales para aplicaciones Gigabit (40GBASE-SR4) y de 100 Gigabit (100GBASE-SR4) que usan 8 fibras con 4 que se transmiten y 4 que se reciben a una velocidad de 10 o 25 Mb/s.


We’ve just posted Version 5,1 Build 4 of the Versiv software for the following products:
