50-Micron Multimode Duplex
Fiber Optic Cables
. These cables provide three times the bandwidth
of 62.5-micron cables! That means you get reliable performance over
long distances.
long distances.
Speaking of distance, these cables support longer link lengths than
62.5-micron cable at 850 nm. While 62.5-micron fiber cables support
850-nm links up to 220 meters (721.8 ft.), our
850-nm links up to 220 meters (721.8 ft.), our
50-Micron Multimode
Duplex Fiber Optic Cables
can be used in links as long as 550 meters
(1804.5 ft.)!
Our 50-micron fiber cables are built for today’s and tomorrow’s
networks. They’re perfect for Ethernet, storage area networks,
high-speed parallel optics interconnects, and other high-speed/
high-capacity interconnect applications. This is the fiber cable you’ll
want to have for emerging technologies.

OVERVIEW
As today’s networks expand, the demand for
more bandwidth and greater distances increases accordingly.
Thus, there is a renewed interest in 50-micron fiber optic cable.
Although introduced in 1976, 50-micron cable has not
experienced the widespread use in North America that 62.5-
micron cable has, which was introduced in 1986.

Although introduced in 1976, 50-micron cable has not

These cables share many characteristics. Although 50-micron
fiber cable features a smaller core, which is the light-carrying
portion of the fiber, both 50- and 62.5-micron cable use
the same glass cladding diameter of 125 microns. Because they
have the same outer diameter, both types of cable are equally
strong and are handled in the same way. Also, 50-micron cable
and 62.5-micron cable both use LED and laser light sources.

As with 62.5-micron cable, you can use 50-micron fiber in all
types of applications: Ethernet, FDDI, 155-Mbps ATM, Token Ring,
Fast Ethernet, and Gigabit Ethernet. It is recommended for all
premise applications—backbone, horizontal, and intrabuilding
connections—and it should be considered especially for any new
construction and installations.

The big difference between 50-micron and 62.5-micron
cable is in bandwidth—50-micron cable features three times the
bandwidth of standard 62.5-micron cable. At 850 nm, it’s rated
at 500 MHz/km versus 160 MHz/km. The 850-nm wavelength is
becoming more important as lasers are being developed and used
more frequently as light sources for networks.

becoming more important as lasers are being developed and used
more frequently as light sources for networks.
Other differences are distance and speed. The bandwidth an
application needs depends on the data transmission rate. Usually,
data rates are inversely proportional to distance. As the data rate
goes up (MHz), the distance that rate can be sustained goes
down. So a higher fiber bandwidth enables you to transmit at
a faster rate or for longer distances. In short, 50-micron cable
provides longer link lengths and/or higher speeds in the 850-nm
wavelength. For example, the proposed link length for 50-micron
cable is 550 meters versus 220 meters for 62.5-micron cable.

technically speaking
As a general rule, use ceramic ferrules (used in the
50-Micron Multimode Duplex Fiber Optic Cables) for critical
network connections, such as backbone cables or for
connections that will be changed frequently. Ceramic ferrules
are more precisely molded and fit closer to the fiber,
which gives the fiber optic cables a lower optical loss.
