What is a Transceiver and Why is it Important?
A transceiver is a device that sends and receives data over optic signal.

Transceivers are used in many different environments, such as the switches in equipment rooms on each floor. In a sense, where there is a network, there is an optical module. There are many types of optical modules. From the form factor, there are GBIC, XFP, SFP, SFP+ QSFP+. The most common types of optical modules in recent years are SFP and QSFP. The most common module in SFP modules is the multimode optical module SFP-10G-SR, and the most common module in QSFP is QSFP-40G-SR4. Both models are common modules for data centers and enterprise networks. They are cost-effectivef , have excellent performance, low power consumption and stable performance. Ideal for these short range applications.
Types of SFP Modules
Common optical modules include SFP-1G-SX, which is used with multimode fiber for short-distance transmission. SFP-1G-LX/LH with single-mode transmission, the distance can be up to 10km. The transmission distance of sfp-1g-ex can reach 40km, and the transmission distance of sfp-1g-zx can reach 80km. In addition, there are some special models of modules are very common. The special types of SFP modules are bidi, cwdm, dwdm and copper.
Bidi is a type of module that carries data in both directions on the same fiber. CWDM is a type of module that transmits data on multiple wavelengths across one fiber. DWDM is a type of module that transmits data on multiple wavelengths across multiple fibers. Copper is a type of module that transmits electric signal across twiseted pair cable.
How to choose transceivers manufacturer
Choosing an optical module manufacturer depends on the following points. The first is whether the enterprise is reliable and whether it can provide various certificates and parameter files of the optical module. Furthermore, you need to choose products at the right price according to your budget. The last is whether the after-sales service is perfect. QSFPTEK is a china transceiver manufacturer offers transceivers for 11 years. It has a complete range of optical modules with very competitive prices. All products offered by QSFPTEK can have a 3-year warranty and 90-day return and exchange eligibility. Ensure customers worry-free use.
How to Choose Which Transceiver Fits Your Network Needs?
Low power transceivers are typically used for short range communication, such as in a home WiFi network. They are usually inexpensive and easy to install. For instance, the SFP-10G-SR module can transmit over 300m via om3，sfp-1g-sx module can transmit 500m via om4.
High power transceivers are typically used for long range communication, such as in a metro politian network. They are usually more expensive and require professional installation. For instance, the sfp-10g-zr module transmit 80km via os2.
