The optical cat is the "optical modem", which refers to the transceiver device that converts the optical Ethernet signal into other protocol signals, and also plays the role of modulation and demodulation. The optical cat is also called a single-port optical transceiver. This device serves as a relay transmission device for the local network, and is suitable for optical fiber terminal transmission equipment of base stations and leased line equipment. For multi-port optical transceivers, they are generally called "optical transceivers". For single-port optical transceivers, they are generally used at the user end. They work similarly to the baseband modems commonly used in WAN dedicated line (circuit) networking, and are called "optical modems." "Optical cat", "optical modem". 
Light cat's working principle Light cat's equipment uses large-scale integrated chips, simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function.
The optical cat is a device similar to the baseband modem (digital modem). Unlike the baseband modem, the optical fiber dedicated line is connected to it, which is an optical signal. It is used for the conversion of photoelectric signals and the conversion of interface protocols in the wide area network. It is the access to the router through the access router. The photoelectric transceiver uses the photoelectric signal conversion in the local area network, but only the signal conversion, and there is no interface protocol conversion. 
The scope of application of optical cats only talks about Ethernet optical cats, which are mainly used when the distance exceeds 20KM. In the middle, it needs to be transferred through optical transmission equipment such as SDH / PDH.
In general, the speed of the optical cat is packaged on a 2M circuit, so the difference of the optical transceiver of the optical cat is also its speed. The optical cat is 2M and the optical transceiver is 100M.
General application scenarios:
Customer-Ethernet optical cat-optical cable-E1 optical cat-2M cable-central office SDH optical transceiver-another office SDH optical transceiver-PDH optical transceiver-E1 to Ethernet protocol conversion-customer equipment (Ethernet switch or computer, etc.).
Of course, there are V.35 optical cat, V.24 optical cat, RS-232 optical cat and so on. The application is similar to the above.
Electric Kettle are made by food grand stainless steel and Polypropylene. It helps you to have a 1.8L bottle of boiled water in 5 minutes. Type 201 Stainless stell is the main material for the electric kettle housing. sometimes called a tea kettle or teakettle, is a type of pot, typically metal, specialized for boiling water, with a lid, spout, and handle, or a small kitchen appliance of similar shape that functions in a self-contained manner. Kettles can be heated either by placing on a stove, or by their own internal electric heating element in the appliance versions.
Features:
360-degree swivel base: Great way with cordless pouring; kettle lifts off base for cord. Separate base to move kettle conveniently, 360°rotation design.The cord can be wrap neatly into the base bottom for easy storage. The concealed stainless steel heating element brings fresh hot water with no metal Taste.
Soft Handle for easy using: Comfortable stay-cool handle; brushed stainless steel finish. Cool-touch buttons and ergonomic stay-cool handle.
Large Capacity for Multiple Cups: 1.8 L large capacity, with Max. water level inside the kettle. almost 1.5x the size of most tea makers. Brew up to 6oz at once! Perfect for small gatherings & parties!
Fully Stainless Steel Faster Boils: Stainless Steel Interior cover with no plastic taste. Boils water rapidly, save more time and energy. Faster than the microwave & safer than your traditional stovetop teapot.
On/off switch with LED light.: Automatic On/Off switch makes life easier. No need standing by for hot water. It shuts down when reaches a full rolling boil. Boil-dry and overheat protection to ensure the safety use.
Time Saver & Higher Safety: 1500 watts energy efficient for quick heat-up time brings water to a boil, Fast boil, auto shut off and boil dry protection technology with three-prong plug.
Brushed stainless steel housing
