Optical Transceiver

What is an optical transceiver?

An optical transceiver is an optoelectronic device that converts electrical signals into optical signals. It can convert electrical signals from electrical equipment into optical signals and launch them into optical fibers for transmission; it can also receive optical signals in optical fibers and convert them into electrical signals for use by electrical equipment.

Optical transceiver functions:

• Photoelectric conversion: Convert electrical signals into optical signals, or convert optical signals into electrical signals.
• Optical signal modulation: Modulates optical signals to transmit information.
• Optical signal amplification: Amplify the power of optical signals to increase transmission distance.
• Optical signal filtering: Filter out noise and interference in optical signals.

Applications of optical transceivers:

• Communication network: used to build various communication networks such as backbone networks, metropolitan area networks, and access networks.
• Data center: used to connect servers, storage devices and other equipment to build a high-speed Internet network.
• Industrial control: used in factory automation, power systems, transportation and other fields.
• Medical system: used in hospital information systems, telemedicine and other fields.

Types of optical transceivers:

• Classified by transmission rate: Gigabit optical transceivers, 10 Gigabit optical transceivers, 40 Gigabit optical transceivers, 100 Mbit optical transceivers, etc.
• Classified by transmission distance: short-range optical transceivers, medium-range optical transceivers, long-range optical transceivers, etc.
• Classified by wavelength: single-mode optical transceivers, multi-mode optical transceivers, etc.
• Classified by packaging form: SFP, GBIC, XFP, QSFP, etc.
