Insertion Loss and Link Loss Testing
Paired with a RIFOCS 555B or 557B optical power
meter, the 255A serves as an ideal 1300nm LED
source for testing the insertion loss of multimode and
single-mode fiber optic cables and connectors. The
255A can also be used with an optical power meter
for link loss testing of installed cable plants.
With a calibrated launch optimized for 62.5/125µm
graded-index multimode fiber, the 255A LED source
is particularly useful for testing and maintaining local
area networks (LANs), premises networks, fiber distributed data interfaces (FDDI), and some telecommunications systems. The 255A may also be used for
other multimode and single-mode fiber types.
The 255A LED source is fitted with a precision
Universal Connector Interface (UCI), which ensures
maximum accuracy and repeatability when performing critical measurements on fiber optic systems. A
comprehensive range of UCI adapters is available for
all industry standard fiber optic connectors.
In addition, controlled launch condition versions of the
255A are available to meet the demanding requirements of military, aerospace, shipboard, and transportation applications. Call RIFOCS Corp., or your
local RIFOCS representative for more information.
