Data Sheet
Description
The 125 MBd Versatile Link (HFBR-0507Z Series) is the
most cost-effective fiber-optic solution for transmission
of 125 MBd data over 100 meters. The data link consists
of a 650 nm LED transmitter, HFBR-15X7Z, and a PIN/pre-
amp receiver, HFBR-25X6Z. These can be used with low-
cost plastic or silica fiber. One mm diameter plastic fiber
provides the lowest cost solution for distances under 25
meters. The lower attenuation of silica fiber allows data
transmission over longer distance, for a small difference
in cost. These components can be used for high speed
data links without the problems common with copper
wire solutions, at a competitive cost.
The HFBR-15X7Z transmitter is a high power 650 nm
LED in a low cost plastic housing designed to efficiently
couple power into 1 mm diameter plastic optical fiber
and 200 μm Hard Clad Silica (HCS^®) fiber. With the recom-
mended drive circuit, the LED operates at speeds from
1-125 MBd. The HFBR-25X6Z is a high bandwidth analog
receiver containing a PIN photodiode and internal tran-
simpedance amplifier. With the recommended applica-
tion circuit for 125 MBd operation, the performance of
the complete data link is specified for of 0-25 meters with
plastic fiber and 0-100 meters with 200 μm HCS^® fiber. A
wide variety of other digitizing circuits can be combined
with the HFBR-0507Z Series to optimize perfor-mance
and cost at higher and lower data rates.
