The difference between optical transceivers and fiber optic transceivers

Optical transceivers and fiber optic transceivers are devices for photoelectric conversion. What is the difference between them? At present, the long-distance data transmission used in many smart projects basically adopts optical fiber transmission.


The connection between them requires optical transceivers and fiber optic transceivers to achieve. So, how should the two be connected, and what should be paid attention to?


1. Optical transceiver


The function of the optical transceiver is also the conversion between photoelectric signals, which is mainly used as the carrier of transmission between the switch and the device, and the principle is the same as that of the optical fiber transceiver.


It's just that optical transceivers are more efficient and secure. Optical transceivers are classified according to package forms. The common ones are SFP, SFP+, XFP, SFP28, QSFP+, QSFP28, etc.


Ⅱ. Optical fiber transceiver


Optical fiber transceiver is a device that converts short-distance electrical signals and long-distance optical signals. It is generally used in long-distance transmission, and is transmitted through optical fibers to convert electrical signals into optical signals and send them out.


At the same time, the received optical signal is converted into an electrical signal at the receiving end. Optical fiber transceivers are also called  fiber converters in many places.


As one of the biggest fiber optic transceiver manufacturers in China, we provide an inexpensive solution for users who need to upgrade their systems from copper to fiber and lack capital, labor or time.


Ⅲ. What is the difference between optical transceivers and fiber optic transceivers?


1. Active and passive


An optical transceiver is a functional module, or an accessory. It is a passive device that cannot be used alone. It can only be used in switches and devices with optical transceiver slots. The optical transceiver is a functional device and is a separate active device. The device can be used alone when plugged in;


2. Upgrade configuration


The optical transceiver supports hot swap, and the configuration is relatively flexible; the optical transceiver is relatively fixed, and it will be more troublesome to replace and upgrade;


3. Price


Optical fiber transceivers are cheaper than optical transceivers and are relatively economical and applicable, but many factors such as power adapters, light status, and network cable status must also be considered, and the transmission loss accounts for about 30%;


4. Application


Optical transceivers are mainly used in optical communication application, such as the optical interface of aggregation switches, core routers, DSLAM, OLT and other equipment, such as: computer video, data communication, wireless voice communication and other optical fiber network backbone network;


Optical fiber transceivers are used in actual network environments that cannot be covered by Ethernet cables and must use optical fibers to extend the transmission distance, and are usually the access layer applications of broadband metropolitan area networks;


Ⅳ. What matters should be paid attention to when connecting optical transceivers and fiber optic transceivers?


1. The speed of the optical transceiver and the optical transceiver must be the same, 100M to 100M, 10G to 10G, 10G to 10G.


2. The wavelength and transmission distance must be consistent, for example, the wavelength is 1310nm or 850nm at the same time, and the transmission distance is 10km;


3. The type of light must be the same, single fiber to single fiber, double fiber to double fiber.


4. The fiber jumper or pigtail must be connected to the same interface. Generally, the fiber transceiver adopts the SC port, and the optical transceiver adopts the LC port.
