Charles Industries New Above-Grade Fiber Cross-Connect Pedestals Bring Cost Savings To FTTH

Wednesday, September 30th, 2009

Rolling Meadows, IL–(Marketwire) – Charles Industries, Ltd., a leading provider of outside plant innovations for communications service providers, has expanded its industry-leading family of fiber optic pedestal lines with the introduction of Charles Fiber Cross-Connects (CFXC) for point-to-point architecture fiber networks. CFXC provide a convenient cross-connect and testing point between the feeder network and the distribution field in Fiber-to-the-Home (FTTH) networks. Compared to traditional metallic cross-connect cabinets, their above-grade pedestal form factor is more convenient and less costly to install.

Unlike metallic cross-connect cabinets, the lift-off dome design of CFXC pedestals provides flood-proof environmental protection, allowing them to be installed in almost any location. Their compact size compared to large cabinets makes them easier to install and ideally suited to small communities and neighborhoods. Right-of-ways are no longer a concern and the units can be economically placed directly in the ground without the need for an expensive concrete pad.

CFXC feature a pre-stubbed cross-connect bulkhead with user-specified SC/APC or SC/UPC connectors. The bulkhead is sealed inside an inner dome that protects connectors from dust, insects and other contaminants. Routing guides are provided for organized fiber management of shielded or all-dielectric ribbon or loose tube fiber cable. Once placed in the network, technicians may turn up new customers quickly and easily by placing a pre-connectorized jumper from the feed panel to the distribution panel, all conveniently located on the front panel of the bulkhead

“Placing metallic cross-connect cabinets is often cost-prohibitive in small subdivisions and groups of homes,” says Minesh Patel, vice president of Charles Industries’ OSP Business Unit. “Charles Fiber Cross-Connect Pedestals are right-sized for these applications, with room for future expansion. By utilizing CFXC and doing away with permits and concrete pad placements, service providers realize a substantial cost savings.”

CFXC are available in three pedestal diameters and five frame sizes with up to 48 (8″), 72 (8″), 96 (10″), 144 (12″), or 288 (12″) fiber connections. Both stake-mount and vault-mount configurations are available. Vault-mount models are ideal for locations that require splice case or slack cable storage at the same location as the cross-connect placement.

CFXC join Charles Fiber Flexibility Point (CFFP) and Charles Fiber Distribution Point (CFDP) Interconnect pedestals in providing service providers a full range of pre-connectorized, above-grade fiber distribution solutions. CFFP Pedestals offer the same design and environmental protection features as CFXC Pedestals, but are intended as a cost-effective alternative to placing Fiber Distribution Hubs in the outside plant. Likewise, CFDP Interconnect Pedestals provide an above-grade alternative to optical interconnect-connect cabinets.

Optametra, LLC Coherent Lightwave Signal Analyzers™ Now Available for 100G Physical Layer Test

Sunday, September 20th, 2009

Optametra announces the availability of its OM4105 and OM4106 Coherent Lightwave Signal Analyzers with bit rates to 112 Gb/s (100G DP-QPSK). The higher data rate is also available as an upgrade to those who have already purchased the OM4005 and OM4006 40G analyzers, announced earlier this year at OFC/NFOEC 2009. Both the 40G and 100G versions of the OM4000 series analyzers enable simultaneous measurement of any fiber modulation format, including coherent dual-polarization (DP) QPSK, and subsets such as differential QPSK.

“Optametra’s OM4000-series Analyzers capture the complete electric field of the optical signal; they are universal, and measure everything that can be known about the signal–within the bandwidth of the digitizer or oscilloscope–while not taking shortcuts at the expense of losing valuable data,” said Daniel van der Weide, the company‘s VP of Engineering.

Optametra’s software calibrates and processes real-time burst-mode constellation diagram displays, eye-diagram displays, bit-error detection (BER), polarization (Poincaré sphere), and more. The software is the most complete and flexible available today, and upgradable by design. It addresses challenging applications such as polarization scrambling, recirculating loops, and arbitrary (user-defined or PRBS) patterns, which means it is useful for actual transmission experiments, not only for tuning a transmitter. Additionally, Optametra’s Pro-version software option allows customers access to all variables in the analysis via Matlab, giving them an excellent platform for developing and testing proprietary algorithms including CD compensation, PMD compensation, new proprietary modulation schemes, pass-fail criteria, or any idea that can be coded in Matlab. Thus, “The OM4000 series of 100G Coherent Lightwave Signal Analyzers™ are perfectly suited for the R&D Lab, Production Floor, and Final-Test,” said Rob Marsland, President of Optametra.

U.S. Pricing and Availability
Optametra’s OM4105 and OM4106 100G Coherent Lightwave Signal Analyzers™ may be ordered today, with standard lead-times of 12 weeks ARO, depending on configuration and current availability. 100G pricing starts at $137,700 in the U.S. Optametra’s products work with all four-channel 40 Gs/s or faster real-time oscilloscopes, including those from Tektronix, Agilent, and LeCroy, further future-proofing the investment in coherent fiber measurements.

Additional information is available at www.optametra.com, including high-resolution images and video.
