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.
