Mitsubishi, Alcatel and Honeywell launch new products

Mitsubishi offers 10 Gbit/s electroabsorption modulated DFB laser

The Electronic Device Group of Mitsubishi Electric & Electronics USA has unveiled a new 10 Gbit/s electroabsorption (EA) modulated DFB laser intended for DWDM transmissions up to 50 km. The ML9XX31 enables designers to use the maximum number of wavelengths available in the C-band, enabling several devices to be multiplexed to achieve data transmission rates potentially as high as 460 Gbit/s in metropolitan area networks.

The integrated modulator is a single InGaAsP chip solution, which reduces power consumption and in contrast to alternative devices using lithium-niobate benefits from large-scale production. In addition, the ML9XX31 laser is more flexible for optical network system design as a result of the 46 wavelengths available throughout the C-band (1530-1565 nm), which is specified by the ITU.
The transmit distance of up to 50 km is achieved by the low chirp in the laser, which allows a power penalty of less than 2.0 dB. The device has a typical operating current of 60 mA at 5 mW of output power, as well as a typical side mode suppression ratio of 40 dB. It also has typical rise and fall times of 30 ps each, with an extinction ratio of 11 dB.

The ML9XX31 laser diode is available in a chip-on-carrier package and is sampling now, with volume production scheduled for October 2002.

Alcatel Optronics launches a new electroabsorption modulator laser

Alcatel Optronics has launched a new electroabsorption modulator laser integrating a wavelength locking function; the Alcatel 1945 LMM. This laser, with a precision controlled emitted wavelength, is the ideal product for 10 Gbit/s DWDM metropolitan transmission networks.

"This new laser demonstrates Alcatel Optronics advance in both monolithic and hybrid integration. This represents a real breakthrough since it provides a stable, compact and cost effective solution to increase channel density in metropolitan systems," stated Philippe Brégi, COO of Alcatel Optronics.
The Alcatel 1945 LMM electro absorption modulator laser covers the C band, and has an optical power output of up to 3 dBm. It supports transmission distances of up to 80 km on standard optical fiber.

Available in a standard 7 pin butterfly package with GPO or K connector, it combines a monolithically integrated laser modulator chip, a Fabry-Perot filter and two photodiodes accurately controlling optical power and emitted wavelength into the optical fiber. The choice of an air-gap Fabry-Perot filter leads to very high wavelength stability, +/- 1.25 GHz, for an external temperature range from 0°C to 70°C.

Honeywell introduces 10 Gbit/s serial VCSEL

The VCSEL Optical Products business of Honeywell has announced its new family of 850nm 10 Gbit/s serial VCSELs and PIN-preamp products. The 10 Gbit/s serial VCSEL and PIN-preamp products offer a high performance, cost-effective solution for short- range multimode fiber optic links between and within network equipment. They are a response to the market s desire for greater data transfer, smaller sized components, optimized performance and outstanding reliability at a lower cost.

Honeywell s 10 Gbit/s solutions include both optical subassembly (OSA) and optical front-end (OFE) options. All are fully compliant with 10 Gigabit Ethernet and Fiber Channel networking standards. The OSAs and OFE are designed to be compatible with the footprints specified by various multi-source agreements such as the XENPACK, XGP or XFP MSAs.

The 10 Gbit/s serial emitter product offers extremely low power consumption and is based upon a directly modulated 850 nm VCSEL. The receiver product consists of an 850 nm pin detector and pre-amplifier. The emitter and receiver are each packaged in microwave ceramic component packages that includes a power monitor photodiode for the VCSEL on the transmit side and, a GaAs pin detector coupled to a high gain transimpedance amplifier with automatic gain control (AGC) and DC restoration on the reverse side. The units can be driven from a differential CML electrical interface.
