The 201 type of modem is designed to transmit data at 2400
bits per second. Because of the bit rate, the 201 type is unable to use the FSK modulation method.
Cheung of Bellcom's Holmdel facility have shown that LEDs of both the surface-emitting and edge-emitting variety can produce enough power to send a signal of 140 million
bits per second (a technologically reasonable rate) over several kilometers of fiber.
In those terms the outstanding record breaker of last week's Conference on Optical Fiber Communication '85, held in San Diego, was an experiment by AT&T Bell Laboratories, which reached 1.37 trillion bitkilometers per second, in taking a signal of 20 billion
bits per second over a fiber 68.3 kilometers long.
As for that, according to a company that sells a variety of switches and adapters and whatnot for developing networks, "10 Gigabit Ethernet (IEEE 802.3a) offers data speeds up to 10 billion
bits per second" and while the 10 billion
bits per second might not resonate, it goes on to explain, "Enterprises use 10 Gigabit Ethernet switches to provide Layer 2 networking for very highspeed network applications--mostly in the data center or server room."
Their "writing" averages 8
bits per second and "reading" averages 20
bits per second.
To comply, providers must offer internet service delivering at least 25 million
bits per second (Mbps) downloads and 3 Mbps uploads to their rural customers.
The resulting radio is planned to be capable of doubling 256-QAM data rates, or 16
bits per second per Hertz, at a noise level representative of 256-QAM alone.
Gbps stands for billions of
bits per second and is a measure of bandwidth on a digital data transmission medium such as optical fiber.
Core networks that transmit signals over long distances utilize low-loss wavelength range to attain maximum transmission capacity of 100 tera
bits per second (Tbps) per fiber.
