Mitsubishi Electric claims the most effective tunable dispersion compensators for countering signal degradation in long-reach WDM. They enable automatic, remote adjustment for temperature fluctuation in installed fibre.
Using FBG technology and a temperature control mechanism, the FQ-40C can tune the optical signal up to 350ps/nm for 40Gbit/s; the FQ-10E up to 1,400ps/nm for 10Gbit/s. www.mitsubishielectric.comPandatel's ET-CG modular and flexible Gigabit Ethernet media converter caters for all Ethernet speeds using auto sensing.
It receives electrical data in 10/100 or 1000BaseT standard on the line side via an RJ45 port, converts it into optical signals and transmits it with a fixed SC plug connection or a slot for a plug-in GBIC or SFP module.
A choice of six single- or multi-mode lasers enables reach of up to 70km. In-built management enables integration into existing networks and remote configuration. Available as a 3U rack mount card or in a single-slot 42x145x225mm housing.

Release 5.0 of Nortel's OPTera Metro 5000 Multiservice Platform adds service interfaces and features, enabling the optical layer to be "operationalised" with improvements to planning and management tools.
It enables new services like business continuity, disaster recovery, video, and content networking.
Features include ring-to-ring interconnect between OPTera Metro 5200 rings. Nortel has also doubled the wavelength density of 5100 and 5200 through a 2.5Gbit/s agile transponder card.

Lightscape Networks' BroadGateT µLAN multi-service access platform functions as an STM-1/ OC-3 add-drop multiplexer and terminal multiplexer (TM) or dual homing protected TM.
It extends the services of the XDMT hybrid optical networking platform for data connectivity in the access network. Together they provide carrier-class end-to-end voice and data services with the reliability and protection of SDH and SONET.
The multi-service design combines TDM voice and data services. It aggregates both leased-line and Ethernet services onto the SDH/SONET access network via STM-1/OC-3 uplinks. Data traffic is mapped onto VC-12/VT1.5 SDH/SONET containers, scaling from 2/1.5 to 100Mbit/s. www.lightscapenetworks.comTyco Electronics' Laser Diode Inc has an improved PINFET optical receiver for both high sensitivity and wide dynamic range over a customisable bandwidth range.
The low-profile DIP package combines both standard pin-outs with high reliability to satisfy Telcordia specifications.
Options include automatic gain control (AGC), a silicon-based detector for 850nm applications, and single-mode fibre coupled pigtail.
LDI's PINFET integrates a PIN photodiode and a discrete, high-performance TIA stage. Light is coupled into the detector through a multi-mode fibre pigtail.
The LDPF's sensitivity is maximised at a chosen bandwidth. The LDPW includes AGC and has been optimised for wide dynamic range (up to 0dBm) while maintaining high sensitivity. www.laserdiode.comArden Photonics Ltd's VF-20 is a Michelson-interferometer-based inspection system for optical component manufacturers, cleaver manufacturers and repair houses and research and development facilities to check the quality and end angle of cleaved or polished fibres.
A long working distance avoids damage to the fibre end. The user can select either inspection mode, to view fibre-end quality, or interferometric mode, to characterise surface flatness.
Removable precision fibre holders allow measurement of the quality of both perpendicular and angled fibre ends.

Aurora Networks' Aurora Ethernet Transport solution for multiple system operators (MSOs) provides exceptional ROI, ease and flexibility for MSOs deploying business services to SOHOs and small to medium-sized businesses (SMBs) passed by their networks.
It offers 1.6Gbit/s bandwidth per wavelength, which can be extended using DWDM. MSOs can provide their business customers with a wide variety of voice, video and data services, including VLANs, VPNs and leased line replacements. The solution's low latency (under 1ms) makes it ideal for latency-sensitive applications such as video streaming and VoIP. MSOs can expect a rapid return on investment, typically within six months of deployment. www.aurora.comOpto Speed has launched an ultra-high-power broad bandwidth superluminescent light emitting diode (SLED) with 17mW output in a single-mode fibre and a bandwidth of 40nm at FWHM, centred on 1480nm, suited for CWDM test and measurement.
It is part of the D20 family, which covers 1300, 1400, 1550 and 1620nm with a single-mode fibre coupled output power of >15mW.
The 14-pin DIL package pigtailed SLED1480D20 is being sampled, with 14-pin butterfly packaged SLEDs available upon request.

Enterasys Networks' 10 Gigabit Ethernet modules for the X-Pedition ER16 routers and Matrix E1 Optical Access Switch (OAS) enable real-time delivery of high-bandwidth, advanced applications across local-area network, wide-area network and metropolitan-area network environments.
Users can now run end-to-end 10 Gigabit Ethernet across an enterprise network when using these new modules and Enterasys' Matrix E1 switches.www.enterasys.comValdor Fiber Optics' HeptoPort multi-channel interconnection technology uses a seven-fibre port with 2D Self-Alignment IMPACT MOUNT technology, which enables a single optical element to be shared by up to three ADMs. It allows a single Faraday-Rotator assembly to be shared by seven self-aligned fibres, producing seven independent isolators in a single small-form-factor package.
Valdor Fiber Optics' multi-channel technology can expand the number of fibres from seven to 19 or 37.
Future applications include multi-fibre connectors, hologram waveguides and MEMS.

Sunrise Telecom's Scalable Test Toolkit (STT) is a next-gen testing platform for the design, installation, and maintenance of core, metro, and access networks.
For central office technicians installing and troubleshooting hybrid networks running over DWDM metro rings, the STT integrates DWDM analysis, fibre cable testing, SONET/SDH testing up to 10Gbit/s, and Ethernet testing. Transmitting on and dropping out individual channels brings the advantages and precision of Bit Error Rate testing to DWDM.
STT's modularity ensures that testing can evolve with the network. Its stacking architecture offers flexibility transforming in minutes from a light, single-module test-set for the field to a multi-tasking combination test-set for the lab. In stand-alone mode, users can operate any test module independently.
