基于MEMS技术的可调谐光衰减器(OVA)
October 24, 2002
产品介绍
Santec最新的基于MEMS技术的可调谐光衰减器为WDM系统集成提供了一种袖珍型、低成本的、电可调型光衰减器。这个产品是为克服同类产品中存在的一些技术性和可靠性缺陷而特别设计的，同时保持了它的功能性和机械兼容性。封装的通道数可以是1、4或8个。
各通道的衰减值线性范围为30dB，分辨率高于0.1dB，操作电源为5V d.c.，并具有45dB的保护阻挡功能。插损为0.8dB，PDL小于0.2dB。优异的光学性能、微小的尺寸和较高的输入光功率极限使得这种器件具有广泛的应用性。这些应用包括EDFA控制、DWDM系统发送器或接收器信号水准调制、OADM水准调制或通道阻断。
这种OVA不受外界震动或机械冲击的影响，密封封装确保了产品的长期可靠性。目前我们提供测试用的样品，批量生产将于明年一月开始
Santec's new MEMS based OVA component provides a compact, low cost,
electronically adjustable optical attenuator for WDM system integration.
The unit has been specifically designed to overcome technical and
reliability issues found in similar devices, whilst maintaining
functional and mechanical compatibility. It is available in 1, 4
and 8 channel packages.
Individual channels have a 30dB linear attenuation range with better
than 0.1dB resolution, and operate using a 5V d.c. supply. A 45dB
blocking function is also available. Insertion loss is 0.8dB, and
the PDL is less than 0.2dB. These excellent optical properties,
combined with small size and high optical input power threshold
will enable these devices to be used in a wide range of applications.
These include EDFA control, DWDM system transmitter or receiver
signal level adjustment, and OADM level adjustment or channel blocking.
The OVA is not affected by external vibrations or mechanical shocks,
and is hermetically sealed to ensure long term reliability. Samples
are currently available for testing with volume production starting
in January.
