Transceivers
A transceiver is a bidirectional optical communication device that uses different wavelengths to transmit and receive signals between the optical line terminals (OLT) at the central office (CO) and the optical network terminal (ONT) at the customer premises.
There are two standard ONT transceivers for the customer premises: the diplexer and the triplexer. Both use 1310 nm for upstream and 1490 nm for downstream wavelengths, and for the triplexer - 1550 nm wavelength is utilized for the analog broadcast video downstream transmission.
Applications
Optical transceivers are a key application component of optical communication networks for converting signals between the electrical and optical domain at different data rates, also for different transmission distances over the optical fibers.
The demand for bandwidth is pushing new fiber-based access technologies to the market.
So far, the copper-based access technologies, e.g. the Assymetrical Digital Subscriber Line (ADSL) and cable modem (CM), are widely-used for broadband access networks, but they will not be able to fulfill the requirements of future broadband networks.
In this respect the optical access network architectures are coming into the play, providing the larger bandwidth and lower operation costs. Depending on the location of the fiber termination point, the fiber access network is referred to as fiber-to-the-x (FTTx).
