The advantage of fiber optic transceiver

The main advantage of current optical transceiver is high-speed.

Today,people’s requirements for amount of information get more and more,and requirements for the information transferrate rate get more faster. The optical communication network, as the main pillars of Modern information exchange, processing and transmission, has continued develope to ultrahigh frequency, ultra high-speed and large capacity . Because the higher the transmission rate, the greater information capacity, the cost to send each information is getting smaller and smaller.

The current hot spots of the long-distance high-capacity  is 10Gbit / s and40Gbit / s, according to the ElectroniCast research   the total global consumption of 10 Gbit / s data communication transceivers  increased  to 90 million dollars in 2010 from $ 1.57 million dollars in 2001. In early 2001, the number of 10Gbit / s data communication transceivers of less than 100,000, but by 2003, 10 Gbit / s data communication transceivers increased to 2 million. In the next few years remained  fierce growth in 2005 reached 7 million. Throughout the areas of consumer, following the 10-gigabit Fibre Channel, 10-gigabit Ethernet will have a strong impact. SDH single-channel optical system forward 40Gbit / s improve.In High-speed systems and devices, many companies this year launched a 40Gbit / s system.40Gbit / s key products are: high-power tunable / fixed laser, 40Gmodulator (Inp EAM, LiNbO3EOM, Polymer EOM), high-speed circuit (InP, of GeSi material), wavelength locker, low-dispersion filter, dynamice qualizer, the Raman amplifier, low-dispersion switch 40Gbit/sPD (PIN, APD), tunable dispersion compensation component (TU-DCM), prior to the Corrections (FEC).

From this stage circuit technology for 100Gbit/s,have  close to the limits of the "electronic bottleneck". The higher rate of signal loss caused by power dissipation, electromagnetic radiation (interference), and impedance matching problem will be difficult to solve, even if can be resolved, that have to spend a very large price.
