Positron Adds a Compact HVI
Solution to Its Fiber Optic Isolation
Portfolio
Positron provides reliable isolation solutions to
protect telecommunications circuits entering
substations, power generating plants and cell
site communications facilities. Positron is
expanding its TeleLite Fiber Optic isolation
portfolio by offering the new “compact High
Voltage Interface” (cHVI) solutions. The new
TeleLite cHVI product portfolio can now be
cost-effectively and rapidly deployed in small
applications.
The cHVI product portfolio is designed to
reduce the Cost of Ownership (COO) and
improve operational flexibility. The new
products are designed to facilitate ease of
installation and field maintenance, and
provide the needed flexibility to use the
full portfolio of TeleLite plug-in cards.
This assures exchangeability across all the
TeleLite HVI and cHVI configurations.
TeleLite cHVI is available in -card or 3-card
enclosures with pedestal and solar powering
options designed to function in both inside
and outside installations as well as in a 1U
-slot shelf (see Figure 1). These packages
are preconfigured to meet all applicable IEEE
Recommendations and FCC standards for
High Voltage isolation installations.
cHVI Solutions for the Copper Fiber Junction
Choose from a -card and 3-card cHVI
solution for the Copper Fiber Junction
(CFJ). TeleLite’s cHVI offerings are based on
NEMA-4 compliant enclosures for outdoor
deployments, rated from -40 to +1 7ºF (-40
to +70ºC). They are designed to meet IEEE
1590 recommendations and include terminal
blocks, facility protection options and
additional space for auxiliary equipment.
Options:
• Flexible mounting options include Hframe,
pole-mounted or outside plant
pedestal
• Solar panel powering for CFJ sites,
which do not have access to local hydro
powering
cHVI Solutions for the Optical Equipment
Interface (OEI)
The 1U cHVI solution is ideal for smaller
isolation applications providing for a costeffective
-slot shelf installation solution
that mounts in a standard 19” or 3”
telecommunication rack.
Multiple 1U cHVI shelves can be stacked
and powered from -48V in a daisy chained
configuration for up to three cHVI 1U shelves
when expansion is required.
Special considerations at the 300V point for the
CFJ location
IEEE 1590 recommendations, developed
by protection engineers from the
telecommunications and electrical utility
industries, strongly recommend that the CFJ
be installed at the 300V point i.e. outside the
Zone of Influence (ZOI).
The ZOI and the 300V point will vary from
site to site, depending on soil and grounding
techniques deployed. This may extend the
300V point to several kilometers beyond the
High Voltage location.
10 I May-June 2008 Issue
Positron firmly supports the IEEE
recommendations as locating the CFJ beyond
the 300V point will ensure the safety of
personnel and avoid serious injury.
