What are the advantages of fiber optics?
Fiber optics has several advantages over traditional metal communication lines. They have a much greater bandwidth than metal cables. This means they can carry more data. They are also less susceptible than metal cables to interference, and they are much thinner and lighter than metal wires. This enables the data to be transmitted digitally over fiber optics rather than resorting to analog transmission.

A standardized variant of 10 Gigabit Ethernet ( 10GbE ), called WAN PHY, is designed to inter-operate with OC-192 transport equipment while the common version of 10GbE is called LAN PHY (which is not compatible with OC-192 transport equipment in its native form).
What does OC-3C stand for?
OC-3c ("c" stands for "concatenated") concatenates three STS-1 (OC-1) frames into a single OC-3 look alike stream. The three STS-1 (OC-1) streams interleave with each other so that the first column is from the first stream, the second column is from the second stream, and the third is from the third stream. Concatenated STS (OC) frames carry only one column of path overhead because they cannot be divided into finer granularity signals. Hence, OC-3c can transmit more payload to accommodate a CEPT-4 139.264 Mbit/s signal. The payload rate is 149.76 Mbit/s and overhead is 5.76 Mbit/s.

What is optical carrier transmission rate?
Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks . Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. Thus, the speed of optical-carrier-classified lines labeled as OC- n is n × 51.84 Mbit/s.

What is SONET used for?from gigapackets.com
The built-in protection and synchronised TDM channels make SONET ideal for carrier grade digitized telephone call trunking. But SONET can also transport packetized data including voice, video and data. One use of SONET fiber optic circuits is to transport DS1 signals for T1 lines and DS3 signals for T3 lines over long distances. They can be split off or demultiplexed at the drop off destination. If you have a long haul T1 line, chances are that it is carried at least part of the way on fiber optic channels even though your termination is twisted pair copper.
What is the speed of SONET?from gigapackets.com
The SONET family of line rates spans OC-1 at 52 Mbps on up to OC-768 at 40 Gbps. But in practice, only a few optical carrier levels are standard and readily available. These are OC-3 at 155 Mbps, OC-12 at 622 Mbps, OC-48 at 2.5 Gbps, OC -192 at 10 Gbps and OC-768 at 40 Gbps.
