1.4 Intended Use
The MP2110A can be used for the following applications:
 Evaluating optical transceivers used in optical fiber communications
 Evaluating parts for digital communications
Evaluating optical transceivers used in optical fiber communications
Computer-based and public communications systems transmit and
receive digitalized signals. These signals are converted to electrical or
optical signals optimized for passage through the transmission path,
which may be either coaxial cable or optical fiber. In the communication
where the bit rate is around 100 Gbit/s, the optical transceiver based on
the multisource agreement such as CFP4 and QSFP28 is used.
The optical transceiver includes the transmitters and receivers of which
the bit rate is 25 Gbit/s for 4 circuits. The following figure shows a CFP4
block diagram for 100 Gbit/s.
