3M’s One Pass Fiber Pathway
Enables Fast Installs of FTTP Networks for MDUs
September
2009—To enable fast installation of FTTP networks for multi-dwelling
units (MDUs), 3M Communication Markets Division recently introduced
its One Pass Fiber Pathway. This horizontal cable pathway and drop
cable solution can be installed in just one pass around a hallway
perimeter.
MDU living is a fast-growing market. According to the 2008
“Fiberizing the MDU” report by Sean Buckley, there are
approximately 700 million MDUs worldwide, occupied by one-third of
the global population. By the year 2012, the number of MDUs passed
with fiber could exceed 10 million per year. Economies of scale make
FTTP deployments to MDUs more cost-effective than deployments to
single-family homes.
Using 3M adhesive technology to adhere the One Pass Duct to the
wall, the One Pass Fiber Pathway is compatible with a variety of
wall surfaces. The low-profile design is less obtrusive than
existing horizontal cable pathway solutions, and because it’s
flexible, the pathway conforms well to curved walls often found in
older MDUs. Fewer parts and a continuous, seamless application
process make installation of the 3M One Pass Fiber Pathway quick,
reducing installation time and labor costs compared to traditional
cable pathway and drop-cable solutions. The One Pass Fiber Pathway
is also suitable for use in hotels, hospitals, schools, and small
businesses.
Suitable for indoor use only, 3M One Pass Fiber Pathway is available
in a variety of lengths and pre-loaded with six or 12 single-mode,
bend-insensitive fibers. It can be factory terminated at one end
with SC connectors. The design enables quick plug-and-play
connections to vertical distribution cables in a fiber distribution
terminal (FDT).

Phoenix
Contact’s Wire Duct Keeps Control Cabinet Wiring Organized
October
2009—Phoenix Contact’s new line of wire duct cabinet add-ons
simplify control cabinet wiring. With CLIPLINE wire duct, wiring is
neat and secure, making it easy to replace or add wiring later.
“Fingers” on the ducts have two score lines, allowing easy removal.
The fingers are flexible and will not snap when the user runs wire
through them. The wire duct features a notched score line that
eliminates the need for notching pliers to break off the fingers.
However, breaking the wall will require the use of a cutter.
The cover’s contour allows it to snap on easily and fit securely.
The duct and cover are available as a complete set, or the covers
can be ordered individually. Ranging in size from 25mm to 120mm, the
wire duct is suitable for a variety of applications. The wiring duct
is available in two meter lengths, matching Phoenix Contact’s
standard DIN rail.

Alpha Wire Expands VFD Cable Line with 3-Conductor Versions
October
2009—Alpha Wire now offers its V Series cables in a three-conductor
version. V Series cables are designed specifically for the needs of
variable-frequency drives. The cables use a combination of materials
and symmetrical geometry to minimize problems from voltage
irregularities such as harmonics, corona discharges, and power
distortion.
“VFD systems can stress cables enough to cause intermittent errors
and premature failure of cable or motors,” said Konstantin Khitrik,
product manager at Alpha Wire. “Our four-conductor cables set the
performance standard in creating reliable, durable VFD systems. The
new three-conductor versions give similar performance benefits to
designers in a smaller, less expensive configuration.”
The cable’s specially formulated cross-linked polyethylene
insulation provides superior corona resistance, low capacitance for
longer runs, and excellent low-temperature properties. The
three-conductor cables feature a symmetrical design with the bare
copper ground wires placed in the interstices of the conductors for
uniform conductor-to-ground capacitance and impedance. This
uniformity reduces the probability of motor damage from common-mode
current.
The round, symmetrical design also reduces the diameter of the cable
and increases its flexibility for easier routing and handling.
Available in wire sizes from 16 AWG to 4/0 AWG, the oil- and
sunlight-resistant shielded cables have a PVC jacket and a
temperature range from -40°C to 90°C. The cables use an overall
shield to provide maximum EMI protection over a wide frequency
range. For 16 AWG to 4 AWG, the shielding is a combination of
aluminum/polyester/aluminum foil and copper braid with 85 percent
coverage. For larger gauge sizes, the shielding is double-layer
copper table.
Compatible with systems from all major VFD manufacturers, the new
three-conductor V Series cables are approved to a wide range of
standards that includes UL types TC-ER, 1000-V motor supply cable,
and XHHW-2. The cables allow direct burial without conduit.
