Mitsubishi Electric公司介绍了一种用于每秒10Gbits速率下的STM—64光纤传输的电吸收二极管激光器组件.FU—641SEA—1是为在波长1550nm下传输距离达50km设计的,满足了ITU对S64.2的要求.在远距离网络中,对容量日益增长的要求促进了这种二极管激光器组件的发展,以便在色散800ps/nm下,以1dB功率10Gbits/s的速率为代价,达到一个最低性能.对远距离主传输网络的升级,FU—641SEA—1对现存的密集型波分复用开关方案提供一种廉价的替换办法.该组件具有一个1.55μm的激光二极管,它与一个电吸收调制器集成在一块芯片上.器件的蝶形封装有一个SMA RF输入端和一个光学隔离器.截止频率为12GHz,在2.5 Vp—p时的消光比为10dB,这保证了在10Gbps速率下的性能.(No.49)
Mitsubishi Electric introduced an electroabsorption diode laser module for STM-64 fiber transmission at 10 Gbits / s The FU-641SEA-1 is designed to transmit up to 50 km at a wavelength of 1550 nm and meets ITU requirements for S64 .2 The growing demand for capacity in long-distance networks has led to the development of such diode laser components to achieve a minimum performance at a dispersion rate of 800 ps / nm at a rate of 10 Gbits / s at 1 dB of power For long-distance main transport network upgrades, the FU-641SEA-1 offers an inexpensive alternative to existing denselywavelength-division multiplexing switching schemes with a 1.55μm laser diode that combines with an Electro-Absorption Modulation The device’s butterfly package has an SMA RF input and an optical isolator with a cutoff frequency of 12GHz and an extinction ratio of 10dB at 2.5Vp-p, which guarantees performance at 10Gbps .
