Modulight and AOI launch new 1310 nm lasers
The second laser, the DFB-1310-CX-2-2.5, is designed for SONET S16.1 and L16.1 applications at 2.5 Gbit/s and is ideal for use in metro networks and intermediate reach applications.
The devices are immediately available directly from AOI and are designed to be pin-compatible with industry-standard coaxial modules. In addition to the two digital transmitter lasers, the company will soon offer a version of the device designed for analog transmission over the 50 to 860 MHz frequency range used to transmit cable television signals.
Modulight, Tampere, Finland a manufacturer of high-performance semiconductor components for optical-fiber communication has announced a new family of laser chip products. The Fabry-Pérot laser chips, emitting at 1310 nm, are especially designed for uncooled transponders, transceivers and transmitters. The chips for 622 Mbit/s, 1.25 Gbit/s, 2.5 Gbit/s and 10 Gbit/s components are intended for short and intermediate reach applications like SONET/SDH and ATM data links and transceivers for Gigabit and 10 Gigabit Ethernet, OIF VSR-4, Fiber Channel, and InfiniBand. The 100% tested 622 Mbit/s, 1.25 Gbit/s and 2.5 Gbit/s chips are available in sample quantities immediately and the 10 Gbit/s FP lasers will be sampled to first customers by the end of Q2 2002.
The lasers show excellent high-temperature properties with characteristic temperature in excess of 85 K. Typical slope efficiency is 0.37 W/A at 25°C and 0.28 W/A at 85°C, reflecting the temperature stability of the chip. "The excellent high-temperature performance of these chips gives component manufacturers more freedom in package design, enabling new solutions in transceivers. The absence of a thermoelectric cooler directly leads into reduced packaging cost, smaller power consumption and reduced footprint", says Pekko Sipilä, Modulight s Product Line Manager for transmitter lasers.
