The WDL refers to the variation in attenuation loss over the specified wavelength range. The PDL refers to the variation in attenuation loss over all states of input polarization. In a VOA, WDL and PDL can vary as a function of the attenuation level. WDL and PDL are undesirable because they contribute to increasing differences in optical power between wavelength channels, which in turn increases the need for channel power equalization and increases the cost and complexity of optical networks. Various design approaches have been proposed to reduce WDL in ES-VOA, see for example U.S. Pat. No. 7,295,748.

“In a further development the ES-VOA component is packaged inside a Small Form factor Pluggable (SFP) housing. This product is referred to as SFP VOA. The SFP VOA offers several advantages compared to the stand-alone pigtailed ES-VOA component described above: (1) the SFP VOA is pluggable, the customer can gradually populate SFP VOA slots on the host system board as the system capacity is increased, (2) the SFP VOA pluggability allows for easy replacement, (3) no fiber management is required since the SFP VOA is connectorized, (4) the interface is digital and the attenuation level is set by a firmware instruction from the host board, the customer does not need to design control and drive hardware and does not need to know the specific characteristics of the ES-VOA component.

“However, compared to the stand-alone pigtailed ES-VOA, the SFP VOA suffers from higher WDL and higher PDL. The inventors have investigated the possibility that this may be caused by modal interference between the fundamental mode and co-propagating cladding modes launched in the output fiber..

Well, Thinkgeek has an idea, and intends to “sell” that idea to you with the $ 79.99 Multi- colored Fiber-optic LED Quadcopter. This is one unique quadcopter as you can tell from the name itself, as it will feature flying colors, literally, where you can control the entire shebang from a 2.4GHz remote transmitter.

The Multi-colored Fiber-optic LED Quadcopter is a remote controlled toy with fiber optics thrown into the mix, targeting those who are aged 14 and above. In fact, a single touch of a button would enable you to flip this bad boy up to a full 360 °. Apart from that, it will also make use of a 6-axis gyro in order to tell whether it is hovering about on the right side up. The quartet of fiber-optic LED loops add to the entire visual attraction, where it works best in a large indoor room – make sure it is darkened!

OF-Link Communications Co., Ltd is a manufacturer and exporter specialized in fiber optic passive components. Our company has a lot of fiber optic products , I believe that one where you can find your favorite products , welcome to buy !
