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.

Alors qu’ils peuvent ressembler à des cordons de raccordement à fibre optique, les cordons de test de référence ou TRC (forme abrégée) ne sont pas des cordons de raccordement. Ces cordons qui sont utilisés pour certifier les systèmes de câblage en fibre optique conformément aux normes ANSI/TIA, ISO/CEI et IEEE présentent une petite différence.

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.

Maybe you’ve seen TCL and ELTCTL listed on your cable spec sheet, or perhaps you’ve noticed them on your DSX CableAnalyzer, and you’re simply not familiar with these parameters, what they indicate and if they are required. Nous allons y jeter un coup d’œil.

What is Mode Conversion?

Twenty five years ago this month, a highly animated character popped into my cubicle at Fluke. He had a mandate: find a new business opportunity for Fluke within 100 days. To assist this effort, he also had $100 000 and the authority to employ anyone in the company in the crazy scheme. For some reason, he wanted me, and for some other reason, I couldn’t resist his proposition.
