[NOC Tutor] Fiber Optic Media - Part Two

Once you’ve determined if you need single mode or multimode, loose tube or tight-buffered,
indoor or outdoor cable, fiber-optic cables still have a variety of options from which to choose.
When buying fiber-optic cables, you will have to decide which fiber ratings you want for each
type of cable you need. Some of these ratings include the following:
? Core/cladding sizes
? Number of optical fibers
? LAN/WAN application

[NOC Tutor] Fiber Optic Media - Part One

Fiber-optic media (or optical-fiber, or fibers, for short) are any network-transmission media
that use glass, or in some cases, plastic, fiber to transmit network data in the form of light pulses.
Within the last decade, fiber optics has become an increasingly popular type of network transmission
media. We’ll begin this chapter with a brief look at how fiber-optic transmissions work.

Introduction to Fiber-Optic Transmission

Fiber-optic technology is more complex in its operation than standard copper media because
the transmissions are light pulses instead of voltage transitions. Fiber-optic transmissions

[NOC Tutor] Fiber Channel - Fiber Optic Connector Types

If you have been working with twisted-pair copper, you are in for a bit of a surprise when you
start trying to figure out which fiber-optic connectors you need to use. There’s a regular
rogues’ gallery of them, likely the result of competing proprietary systems in the early days of
fiber deployment.

Fiber-Optic Connector Types
Fiber-optic connectors use bayonet, screw-on, or “snap ‘n lock” methods to attach to the jacks;
a newer connector called the MT-RJ is remarkably similar to the eight-position modular connectors
(a.k.a. RJ-45) that copper folks have been using for years.
To transmit data, two fibers are required: one to send and the other to receive. Fiber-optic
connectors fall into one of two categories based on how the fiber is terminated:
?  Simplex connectors terminate only a single fiber in the connector assembly.
?  Duplex connectors terminate two fibers in the connector assembly.
