What are optical transceiver modules or fiber optic transceivers? How to distinguish them？
In the field of optical communications, there are many devices with similar functions, such as optical modules and fiber optic transceivers, are photoelectric conversion equipment, and sometimes they have different names, optical modules, also known as optoelectronic modules, fiber optic transceivers Also called photoelectric converters, what is the difference between them? Learn about it with the description of this article!
What is a fiber optic transceiver? what's the effect?
Fiber optic transceivers are short-distance electrical signals and long-distance optical signal conversion equipment, generally used in long-distance transmission, through the optical fiber transmission, the electrical signal into optical signals sent out, at the same time, Received optical signal into electrical signals, fiber optic transceivers is a cost-effective solution, do not need to spend a lot of manpower, material and time to complete the network upgrade.
What is the optical module? what's the effect?
The role of the optical module is also the conversion between the photoelectric signals, mainly used for the transmission between the switch and the device carrier, the transmitter side of the electrical signal into optical signals, through the optical fiber transmission, the receiver then convert the optical signal into electrical signals, And fiber optic transceivers are the same principle, but the optical module compared to the transceiver more efficient, security.
What module does the optical module use?
Optical module to use the scope of a simple, there is a need to use the fiber will be used where the optical module, commonly used to optical module equipment and the use of optical module type:
1, Optic transceiver: Vedio Optic Transceiver generally use 1 * 9 single-mode optical module, some high-definition optical transceiver will also use SFP optical module.
2, fiber optic transceivers: 1 * 9 optical module.3, switches: the use of SFP ,, XFP optical modules.
4, fiber network card: using 1 * 9, SFP, SFP + optical modules.
5, fiber high-speed dome: the use of SFP optical module.
6, the base station: the use of SFP, XFP optical module.
7, repeater: using SFP optical module.
According to the above mentioned optical module encapsulation type, users will choose more SFP, SFP +, XFP optical module for example.

What is the difference between optical modules and fiber optic transceivers?
1, optical modules are accessories, generally only in the switch and with optical module slot equipment used; fiber optic transceivers can be used alone.
2, optical module support hot-swappable, flexible configuration; fiber optic transceivers are fixed specifications, replacement upgrade difficult.
3, optical module through the matching equipment; fiber optic transceivers separate power supply.
Do you need to pay attention to the use of optical modules and fiber optic transceivers?
Optical module is a functional module, can not be used alone, in the optical fiber network structure design, we often will use fiber optic transceivers and optical modules together, here we look at the use of fiber optic transceivers and optical modules need to pay attention to what?
1, wavelength and transmission distance must be consistent, such as are used 1310nm or 850nm wavelength, transmission distance is 10KM.
2, fiber jumper pigtail interface selection should pay attention to the general use of fiber optic transceivers SC port, optical module is used LC port.
3, fiber optic transceivers and optical modules must be the same rate, such as Gigabit transceiver corresponding to 1.25G optical module, Fast or even 100 megahertz, Gigabit even Gigabit.
4, the optical module type needs to use the same type, single fiber on the single fiber, double fiber on the double fiber.
