Cable Costs
The price per meter of HCS cable from Avago and OFS is
comparable to the cost of shielded twisted pair wire in
similar volumes. Connectors cost approximately a dollar,
similar to typical twisted pair RJ jack connectors for data
communications. Connector installation requires no epoxy
or polishing, and can be completed in less than a minute
per connector. Therefore the installed cost of HCS cable
is similar to the installed cost of wire links of comparable
performance.
For shorter distance links, pre-connectored plastic fiber
cable assemblies are available from Avago Technologies
Distributors at attractive prices. For example, a 1 m, duplex,
pre-connectored plastic fiber cable (i.e., part number HF-
BR-RMD010Z) has a suggested U.S. resale price of $5.70
in quantities of 500-999; a 10 m cable would cost $16.50.
Again, these costs compare favorably with the cost of data
grade wire cable assemblies at similar volumes.
The costs of the 125 MBd Versatile Link electronics, cable,
and connectors are all competitive with wire solutions.
However, wire solutions frequently incur additional costs
in use due to unanticipated trouble-shooting of electrical
interference due to poor terminations or adjacent sources
of electrical noise. The inherent electrical isolation of
optical fiber results in a more robust solution and lower
cost to the end user.

Notes:
1. Costs of non-Avago components are based on very low volume price
2. Avago Suggested Resale Price in USA, 1994, quantity = 500-999.
3. $28 is a low volume (<1,000) cost estimate. High volume cost is
quotes. High volume prices are below $5.00 for all required non-
Avago components.

Circuits Recommended for use with the HFBR-15X7Z and
HFBR-25X6Z
The HFBR-15X7Z/25X6Z components can be used in a
diverse range of applications. Not all applications can
be addressed with the circuits shown in this publication,
however, the transceiver recommendation which follows is
useful in a wide range of systems which transmit encoded
data at rates up to 125 MBd. If the design suggestions giv-
en in this publication do not meet your needs, you should
contact an application engineer. The Application Engineer-
ing Department of Avago Technologies’ Industrial Fiber
Products Division has numerous circuit recommendations
that will allow the HFBR-15X7Z/25X6Z to address your
specific needs.
Recommended Transmitter
The transmitter shown in Figure 5 is recommended for use
with 1 mm plastic fiber. The transmitter in Figure 5 applies
a forward current of 20 mA to the HFBR-15X7Z LED. If
200 µm HCS
must be increased to 60 mA and the drive circuit shown in
Figure 6 is recommended. The forward current applied to
the HFBR-15X7Z was chosen so that the LED will couple
the maximum amount of light into the core of the fiber
without overdriving the HFBR-25X6Z receiver when short
optical cables are used.
