| AOI Introduces 2.5 Gbps DWDM Lasers Applied Optoelectronics has announced the introduction of dense wavelength division multiplexing (DWDM) transmitter lasers capable of 200 km transmission distances. AOI's proprietary laser technology is the key to ensuring the high performance and reliability of these new devices. These DWDM lasers feature: - Greater than 200 km (3.600 ps/nm) transmission in a single-mode fiber - Integrated high speed, low dispersion penalty distributed-feedback (DFB), multiquantum-well (MQW) laser - Compatible with direct modulation at up to 2.5 Gbps, for OC-48/STM-16 applications - Available in the full range of C-band ITU-T G.692 recommended wavelengths at 100 GHz spacing. - Hermetically sealed, industry-standard 14-pin butterfly package with optical isolator - 25 OHM RF input impedance - Meets GR 468 reliability specifications. Also available is a 10 mW DWDM "butterfly"-packaged laser for 120 km transmission distance without an EDFA. This device combines the low dispersion penalty of the 200 km devices with +10 dBm optical output power. This combination enables amplifier-free operation in many metropolitan-area network applications. write your comments about the article :: © 2006 Networking News :: home page |
