What is the difference and correlation between optical transceivers and optical transceivers?

The optical transceiver is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. In many places, it is also called photoelectric converter or fiber converter (Fiber Converter). ).
The optical transceiver is a device that converts multiple E1 (a data transmission standard of a trunk line, usually at a rate of 2.048 Mbps, which is adopted in China and Europe) into an optical signal and transmits it (its function is mainly to realize electric-light and light). -Electric conversion).
The same thing:
Photoelectric conversion
the difference:
The transceiver only performs photoelectric conversion, does not change the encoding, and does not perform other processing on the data. The transceiver is for Ethernet, runs the 802.3 protocol, and is only used for point-to-point connections.
In addition to the work of photoelectric conversion, the optical transceiver also multiplexes and demultiplexes the data signals. Usually, the optical transceiver comes out of multiple pairs of E1 lines. SDH, PDH optical transceivers are mainly used by telecom operators to provide multiple pairs of point-to-point data circuits. Video optical transceivers are mainly used in security surveillance, distance education, video conferencing, etc., where video transmission requirements are relatively timely, and Transmission control, switching, voice, Ethernet and other signals to meet the needs of multi-service applications, so we sometimes call it integrated optical transceiver.

The Introduction of PCD 
The PCD (Polycrystalline diamond) is a composite material, consisting of sintered diamond particles with a metallic binder. Diamond is the hardest material in absolute terms and therefore also the most resistant to abrasion. Used as a cutting tool, it has a good wear resistance, and a yield superior to traditional sharp carbide. The machined surface roughness with the PCD can reach comparable to the adjustment.

Main applications
â–²Processing of non-ferrous
â–²Aluminum alloys with high or low silicon content (pistons, engine blocks engine, wheels, carburetors, connecting rods, gear boxes, cylinders for brakes, etc.).
â–²Bronze and copper alloys (copper manifolds, engine bearings, bushings, connecting rods eyes, locations pumps etc.).
â–²Tungsten carbide (trafilatori rollers and other components sintered etc).
â–²Pieces composed of aluminum and lead, aluminum engine blocks with cast iron pipes reported
â–²Processing of non-metallic materials
â–²Very abrasive materials, such as ceramics industrial uncooked.
â–²Some fired ceramic: zirconia aluminum oxide, such as spark plugs and insulators.
â–²Glass, plastics with glass fibers, carbon fibers.
The Introduction of PCBN
PCBN has the characteristics of high thermal stability, high hardness, high wear resistance and. It`s inert to iron family element, hence PCBN is mainly used for the machining of high hardness and hard processed ferrous materials, such as d facing alloys, harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals.
