Kamelian is sampling the following:
- A 1310nm semiconductor optical amplifier, complementing its 1550nm Optical Power Booster and Optical Pre-Amplifier. Polarisation-dependent gain is <0.5dB, noise performance <7dB, gain 20dB and saturated output power 10dBm across a 60nm bandwidth, suited to CWDM.
- A 1550nm 4-channel array, which combines monolithic and hybrid integration. Four channels are integrated on a chip and then passively aligned to a fibre ribbon array using a silicon microbench as a carrier. Monolithic integration of a passive waveguide to the SOA's active waveguide reduces alignment tolerances, allowing automated packaging.
ThreeFive Photonics' A4D10 (available for evaluation in first-half 2003) is the second member of its Argo product family of integrated multi-wavelength receivers, launched just six months after the A4D2.5.
The incorporation of four 10Gbit/s channels represents a fourfold increase in capacity without the need for additional space.
The Argo A4D10 addresses the demands for high-capacity interconnections in metropolitan area networks, where space and power consumption are limiting factors.
At a data rate of 10Gbit/s, cross-talk between the channels becomes the critical factor, says chief technology officer Chrétien Herben. "While the A4D2.5 chip was packaged in a 14-pin butterfly package, the A4D10 comes in a 26-pin package of the same dimensions with a coplanar RF output,"
Alcatel Optronics has launched highly compact hybrid integration of planar passive and active technology with MEMS on a silica-on-silicon platform via two complex optical functions used in line terminals or optical add-drop multiplexer nodes:
- An 8-channel variable transparent optical combiner, which monitors and adjusts eight high-bit-rate channels before combining them. It integrates 41 functions such as tap couplers, MOEM-based VOAs, monitoring photodiodes and a passive combiner, offering transparency to wavelength and wavelength spacing.
- A WDM-integrated, amplified demux combines an indium phosphide semiconductor optical amplifier chip with an arrayed waveguide grating to allow amplification and extraction of eight channels at 10Gbit/s with 50GHz wavelength spacing.
Silicon Light Machines' SLM 3000 Reconfigurable Blocking Filter (RBF) uses Grating Light Valve diffractive optical MEMS technology to provide dynamic wavelength management for DWDM. Designed for use in reconfigurable OADMs, it blocks any or all wavelengths, offering complete agility and control of up to 80 channels with 50 or 100GHz spacing.
Compared to traditional static add/drop multiplexers, with a fixed number of channels added or dropped, ROADMs use tunable components to selectively add or drop any channel or group of channels by remotely reconfiguring the system.
ficonTEC's FilterMaster is an approach to full- or half-automated optical filter substrate mapping, for high- and medium-volume production.
FilterMaster increases yield by designating filters for particular quality. Also, it quickly identifies good areas of the filter substrate for maximum yield and minimum downstream processing. FilterMaster integrates high-precision mechanics and optical testing to classify thin film filters, including DWDM, high pass, low pass and gain flattening.
User-definable wavelength and signal quality criteria are measured with an optical multimeter and/or optical spectrum analyser and/or tunable laser source.
Built around its existing Photon.PCSS switching technology, Lynx Photonic Networks' Photon PROTECT 1:4 is the first member of the new 1:N family of photonic protection switching subsystems, designed for 1:4 uni- or bi-directional equipment or traffic protection and available as a subsystem, customised blade or fully packaged "add-on box".
In case of failure in one of the four main units, switching to a shared back-up takes <5ms.
The intelligent subsystem features integrated power monitoring with programmable thresholds and an Intelligent Control Plane, allowing it to run in autonomous or slave mode. It includes integrated power control, signal blocking capabilities, and built-in variable optical attenuation. Photon.PROTECT will continually monitor the failed unit and, upon restoration, revert to the original unit.
