CHAPTER 2: Introduction
The Fiber Optic Converters pass data transmissions between the two standard
types of optical fiber. Transmission lines used to carry fiberoptic signals over
short distances are constructed of a relatively thick fiber called “multimode
(graded index).” A much thinner fiber, “single-mode (graded index),” is used
for transmitting light signals over longer distances. Signal dispersion observed
in multimode fibers is substantially greater than that in single-mode lines
because the size of the fiber and the properties of the light source used.
With a Fiber Optic Converter, you can connect multimode devices such as
RS-232 multiplexors or LAN, ATM (SDH), SONET, or ESCON networks to
the single-mode lines typical of Post, Telephone, and Telegraph companies
(PTTs). This enables these devices to communicate over much greater
distances than those achievable with multimode lines alone.
The Converter module that converts incoming transmissions is entirely
separate from the module performing conversion of outbound signals.
This feature makes the Converters suitable for all applications requiring
unidirectional or bidirectional half-duplex data transmission. You can use
a pair of Converters to connect two devices that have multimode interfaces
across a single-mode line, as shown in Figure 2-1 below, or use one Converter
to connect a multimode device to single-mode equipment, as shown in
Figure 2-2 on the next page.

FIBER OPTIC CONVERTERS
The Fiber Optic Converters can achieve a data rate of up to 250 Mbps. They
also have built-in diagnostic procedures (local and remote loopback) that
comply with the ITU-TSS (CCITT) V.54 standard. Use the front-panel switch
to determine which type of loopback you want and perform these procedures
with a Bit Error Rate Tester (BERT) connected to the Converter in place of
the local device.
The Converters support unipolar two-level codes, such as NRZ, NRZI, RZ,
and biphase (CDP, Manchester), but not bipolar (multi-level) codes (such as
AMI or HDB3) or uncoded signals.
CAUTION!
Use the Fiber Optic Converter-850NM (our product code IC350A) to
convert to and from multimode cable carrying light at 850 nm. Use the
Fiber Optic Converter-1300NM (our product code IC351A) to convert to
and from multimode cable carrying light at 1300 nm. Neither type of
Converter will work with multimode cables designed for the other type’s
wavelength.

CHAPTER 3: Installation
3.1 Unpacking
Carefully remove the Fiber Optic Converter and included equipment from
the container it came in and place the unit securely on a clean surface.
Inspect the container and everything that was in it for damage, and
immediately report any damage you find.
3.2 Placement
Place the Fiber Optic Converter in an area whose temperature is always within
the range of 0 to 40˚C (32 to 104˚F) and whose relative humidity does not
exceed 90% noncondensing.
The Converter should be installed within 5 ft. (1.5 m) of an easily accessible
grounded AC outlet. (The unit’s universal power supply can accept utility
power ranging from 90 to 260 VAC.) Allow at least 3 ft. (90 cm) of clearance
at the front of the unit for operator access. Allow at least 4" (10 cm) clearance
at the rear of the unit to connect and disconnect its power cord.
