Why are SFP optical modules popular?

The volume of the SFP optical module is reduced by half compared with the volume of the GBIC optical module. The number of SFP ports on the same panel will be twice that of the GBIC optical module. The same SFP optical module has a plug-and-play mini optical fiber slot, which conforms to the data With high-density requirements in the center, SFP optical modules will replace GBIC optical modules in data centers in the future.

Popular SFP optical modules

Because the SFP optical modules of GLC-BX-D and GLC-BX-U are powerful and highly sought after, these two types of optical modules support data optical monitoring, allowing users to monitor the performance of optical modules in real time, such as tracking temperature, light Output power, optical input power, laser bias current, transceiver power supply voltage, etc. In addition, the 1000BASE-BX10-D SFP optical module with a transmission distance of 10km, the GLC-BX40-D SFP optical module with a transmission distance of 40km, and the GLC-BX80-D SFP optical module with a transmission distance of 80km are also popular among users.

SFP optical module has the following four advantages:

1. Supports hot swap, which can reduce installation, maintenance and management time;

2. The port is flexible;

3. Robust design enhances reliability;

4. Support digital optical monitoring (DOM) function.

Applicationn of SFP optical module 

1. Short-distance network wiring 1000BASE-T SFP optical module supports 10/100/1000 adaptive and Auto MDI/MDIX, and can be used with category 5 unshielded network patch cords; the transmission distance can reach 100m. The 1000BASE-SX SFP optical module is compatible with the IEEE 802.3z 1000BASE-SX standard, and can be used in a 50μm/62.5μm multimode fiber link with a maximum transmission distance of 550m.

2. Long-distance network wiring 1000BASE-EX and 1000BASE-ZX SFP optical modules can be used with single-mode optical fibers and are suitable for long-distance network transmission. The transmission distance of 1000BASE-EX SFP optical modules can reach 40km, and the transmission distance of 1000BASE-ZX SFP optical modules can reach 80km.

Note: When single-mode fiber (SMF) is used for a short distance, in order to avoid overload of the receiver, an optical attenuator needs to be inserted in the link. After the above program introduction, do you find that the SFP port can support both SFP electrical port modules and SFP optical port modules? No matter how SFP ports and SFP optical modules have high flexibility and compatibility in practical applications, Your best solution for Gigabit Ethernet.
