A Fiberlink® Application Brief | Fiberlink® in Rental & Staging

Avoid the aging when you’re staging.

The advantages of Fiberlink® in rental and staging

applications are as clear as the signals they send.

There’s no doubt about it: copper cabling may be aging, but it still

has many features. Ground loops, signal interference, cross talk,

low-bandwidth, only short distance capabilities, signal distortion,

costly repeaters, signal drop-off, it’s expensive, and who can forget its

prohibitive weight? Of course, when it comes to Rental and Staging,

these are crippling characteristics of the medium and not bottom-line

contributors.

With technical hurdles and challenges like these, it’s no surprise that

Fiberlink® has quickly become the solution of choice for Rental and

Staging.

Immune to all type of interference including ground loops, large

bandwidth capabilities, cheap and durable cabling options and

true plug-in-and-go installation ability, Fiberlink® offers unrivaled prod-

uct performance, reliability and profitability.

There is no technical expertise required to operate any

Fiberlink®; simply connect your inputs and outputs,

add a fiber optic cable and start the show!

And, the results are identical each and every time, installation after

installation, user after user: Pure Performance.

Plus, you can run multiple video, audio and data signals over a single

fiber optic core that is slimmer, lighter and cheaper, eliminating the

need to make multiple costly home runs. At about 8¢ per foot and

dropping, you could even leave the cable behind.

With all the benefits of Fiberlink®,

why deal with the aging when your staging?

Advantages of

Fiberlink®

Ground loops, crosstalk, EMI,

RF and other interference is

literally impossible with

Fiberlink®!

Fiberlink® requires no configu-

ration or technical expertise.

Plug it in and go, it works every

time!

With Fiberlink®, no scaling,

compression, pixel skewing or

other signal manipulation is

performed.

Tactical fiber optic cabling is

actually stronger – stronger! –

than copper cabling!

At about 8¢ per foot, and

dropping, fiber optic cabling

is nearly disposable!

Ruggedized fiber connectors

can take all the abuse of even

the most careless of crews!

Fiberlink® WDM’s offers in-

creased throughput: send the

signals from multiple units over

one fiber optic core!

Applying connectors and

making fiber optic cables in

the field is a snap! No glue.

No epoxies. No polishing.

No hassles.

The anatomy of greatness.

Fiberlink® is the no tools, no tweaks, no troubles solution.

Fiberlink® does not require any special tools for proper

installation. With no settings to adjust, no ratios or signals to tweak,

Fiberlink® offers true plug-in-and-go installation ability. Best of all, it

offers great flexibility and expansion capabilities without having to

retool, rethink, or retweak any of the system components.

Concerned about abuse? Don’t be.

Fiber optic cable is available in many types of constructions

and can be used with the Neutrik® OpticalCon® ruggedized connector system.

If you think fiber optic cable is weak, think again:

Fiber is being used around the world in some of the

most extreme environments that even copper cannot

withstand. And, it is available in PVC, Plenum, Tactical,

Aerial, Underwater Rated, Oil Rated, and more! So,

no matter where you need to run your cable, you can

rest assured that the appropriate fiber optic cable is available.

And, companies such as Neutrik® continue to pioneer rugged and durable

Smart and Simple Installation Situation

Communications Specialties’ deliver smart and simple

fiber optic test equipment essential to any installation.

Fiberlink® light sources and an optical power meter allow for

convenient and easy on-site testing of fiber optic networks during

construction, installation and maintenance.

Fiberlink® 6610 Visible Light Source:

Use the Fiberlink® 6610 Visible 650 nm Light Source to launch a

visible beam of light into the fiber optic core. This assists the user

in discovering cable breaks, identifying individual fibers in bundles

and verifying connection integrity. Use with single mode or multi-

mode fiber.

Fiberlink® 6615 Optical Power Meter:

The Fiberlink® 6615 measures the strength of optical signals at 850,

980, 1310 and 1550 nm wavelengths. Essential for determining

operating loss budgets and troubleshooting any fiber optic

network.

Fiberlink® 6620 Three Wavelength Light Source:

The Fiberlink® 6620 launches a beam of light at 850, 1310 or

1550 nm into the fiber optic core. Use in conjunction with the

Fiberlink® 6615 Optical Power Meter to assess loss budgets and

signal strength.

Cut. Crimp. Connect.

Fiberlink® Field Termination kits offer fiber optic cable assembly

in the field with no polishing, grinding, glues or epoxies.

If you can terminate a BNC connector, you can terminate a fiber

optic connector. That’s because it’s as easy as cut, crimp and

connect with the Fiberlink® Field Termination kit. Simply strip your

cable, crimp on your preferred connector and connect your gear.

It’s that simple.
