Digital Lightwave adds Fibre Channel over OTN, ODTU-03
October 8, 2011Digital Lightwave Inc. says it has added support of Fibre Channel over Optical Transport Network (OTN) and ODTU-03 mapping to the OTN testing features of its flagship NIC Platform.
AFL offers network activation kit for fiber turn-up
October 8, 2011AFL, a wholly owned subsidiary of Fujikura Ltd., now offers Network Activation kits for installation and commissioning of optical equipment in telecom, broadband, and other singlemode fiber-optic networks.
Tektronix Inc. has unveiled a new real-time oscilloscope series
October 8, 2011Fresh off of acquiring optical modulation analyzer provider Optametra (see "Tektronix buys Optametra for optical modulation analyzer technology"), Tektronix Inc. has unveiled a new real-time oscilloscope series that dovetails nicely with Optametra’s technology. The company has unveiled four new DPO/DSA70000D Series oscilloscopes designed to provide real-time sampling rates up to 100 GS/s on two channels and – for those looking to measure coherent receivers for DP-QPSK and similar modulation formats using the Optametra hardware – 33-GHz analog bandwidth on four channels.
Tektronix offers SFP+ automated test and debug via MSO70000 Series oscilloscopes
October 7, 2011Tektronix Inc. has introduced what it asserts is the first comprehensive automated test and debug offering for SFF-8431, SFP+ PHY, and SFP+ Direct Attach Cable Specifications "10GSFP+CU" Measurements. The new TEKEXP SFP-TX option for Tektronix’s DPO/DSA/MSO70000 Series oscilloscopes are designed to help users easily select measurements for SFF-8431 SFP+ testing and perform all measurements with a single button click.
EXFO adds multichannel test to 40G transport test modules
October 7, 2011EXFO Inc. (Nasdaq:EXFO) (TSX:EXF) says it has enhanced its FTB/IQS-8120NGE/8130NGE Power Blazer Next-Generation Multiservice Test Modules and FTB/IQS-8140 Transport Blazer 40/43 Gigabit SONET/SDH/OTN Test Modules with multichannel testing capabilities. The new capabilities are designed improve the efficiency of technicians in 10G/40G labs and network equipment manufacturers by accelerating testing time.
Modular vs. conventional oscilloscope approach for optical coherent modulation analysis
October 7, 2011Modern day high-bandwidth conventional oscilloscopes are typically supplied with a maximum of four input channels (and with as few as one or two channels at a higher bandwidth rating), owing to practical design tradeoffs between bandwidth and channels. However, dual-polarization quadrature phase-shift keyed (DP-QPSK) or quadrature amplitude-modulated (16-QAM) coherent optical modulation systems analysis requires real-time analog-to-digital conversion of four electrical tributaries using very high real-time analog bandwidths of 30 GHz to 45 GHz. Other types of encoding may require many more channels at half of this bandwidth.
