The Difference Between Optical Module Transceivers and Optic Fiber Transceivers

What is the difference between optical modules and optical fibre transceivers, which are both optoelectronic conversion devices? Optical fibres are employed in many of the long-distance data transmissions used in today's sophisticated initiatives.

An optical module and an optic fiber transceiver are required to connect them. So, how should the two be connected, and what should they focus on?

Ⅰ. Transceiver for optical modules

The optical module is also utilized for photoelectric signal conversion and primarily serves as a carrier for data transmission between switches and devices.

SFP, SFP+, XFP, SFP28, QSFP+, QSFP28, and other common optical module transceivers are categorised based on their package form.  And we also have 40g dwdm transceiver.

Ⅱ. Optic fiber transceiver

The optical fiber transceiver is a short-distance electrical signal and long-distance optical signal conversion device that is commonly used in long-distance transmission. It converts electrical signals into optical signals and sends them out via fiber. More information can be found in fiber transceiver wiki.

At the receiving end, the received optical signal is simultaneously transformed to an electrical signal. The optical fiber transceiver is also known as the Fiber Converter in various areas.

Users who need to update their system from copper to fibre but don't have the money, manpower, or time to do it might use the optic fibre transceiver. We can provide a reasonable 400g optical transceiver price.

Ⅲ. What is the difference between an optical module and an optical fiber transceiver?

1. Active and passive participation

Optical module is a functional module, or accessory, that is a passive device that can only be used when inserted in a switch or equipment with an optical module slot; and optic fiber transceiver is a separate active device that can be used alone when plugged into the power supply;

2. Improve the configuration

Optical modules are hot-swappable and can be configured in a variety of ways. Because the optical fiber transceiver is somewhat fixed, replacing and upgrading it will be more difficult.

3. Cost

The optical fiber transceiver is less expensive than the optical module, so it's a good deal. However, when you factor in the power adapter, the state of the light, the state of the network cable, and other factors, the transmission loss is around 30%.

4. Implementation

The optical module transceiver is primarily used in optical network communication equipment such as convergence switches, core routers, DSLAMs, and other optical interface equipment, such as computer video, data communication, wireless voice communication, and other fiber optic network backbone networks.

The optic fiber transceiver is typically used in the access layer of broadband metropolitan networks where Ethernet cables cannot be covered and fiber optics must be used to extend the transmission distance.

Ⅳ. What should be considered when connecting an optical module and an optical fiber transceiver?

1. The rate of the optical module and the optical fiber transceiver must be the same; 100 megabits must be connected to 100 megabits, gigabits must be connected to gigabits, and ten megabits must be connected to ten megabits.

2. The wavelength and transmission distance must be consistent, such as 1310nm or 850nm wavelengths at the same time with a transmission distance of 10km.

3. The light type must be consistent, single-fiber to single-fiber, double-fiber to double-fiber.

4. To connect, the fiber pigtail must have the same interface, which is usually SC for optical fiber transceivers and LC for optical module transceivers.

Compatible Optical Transceiver

Equipment manufacturers of optical modules will encrypt their devices to varying degrees, also known as compatibility. Modules of a particular brand can only be used with devices of the same brand, and cannot be matched with other brand optical modules. Compatibility manufacturers need to conduct different compatibility adaptations on the optical modules. Whether or not they can perfectly solve compatibility issues is particularly important.
