Maximum Data Rate
Maximum data rate is the highest stated rate of digital information transfer supported by the specified cable or interface.
It is expressed in bits per second and related units. A nominal link rate is distinct from usable application throughput, which includes other system constraints.
Maximum Data Rate — HDMI Cable
For an HDMI cable, the rated data capacity constrains supported combinations of video resolution, refresh rate, colour depth and other format conditions.
Compare the actual cable length and supported mode. A data-rate number alone does not identify every HDMI feature, and the source and display must also support the selected operation.
Maximum Data Rate — Ethernet Cable
For an Ethernet cable, supported data rate belongs to the stated network mode and installation conditions. Cable category and channel length help define those conditions.
Compare the complete link, including ports and connections. A cable rated above the equipment’s speed does not increase that equipment’s limit, and nominal link rate is not a guaranteed file-transfer speed.
Maximum Data Rate — SFP USB Cable
For an optical USB assembly, the data-rate limit belongs to its supported USB mode and active link design. It is separate from any power carried or supplied at the ends.
Compare host and device compatibility at the required length. Do not treat a USB connector shape as a speed guarantee or confuse the bus data rate with an audio sample rate.
Maximum Data Rate — SFP Ethernet Cable
For an SFP Ethernet assembly, the data rate must be supported by the host ports, optical modules and fibre arrangement. A physically fitting module can have incompatible operating requirements.
Compare the specified link mode at both ends and its distance conditions. Maximum reach and wavelength are separate properties; a high module data-rate rating does not override an incompatible host port.
