Product Quality:

Since its inception in 2017, SEESUO has continually refined its processes to assure the best possible quality for our customers. The foundational elements of these processes are Record-Keeping and Quality Assurance Testing (QAT). To maintain a robust data archive, each part is individually serialized both in its internal EEPROM memory and on its external label. All QAT results and other important information (e.g., manufacture date, compatibility programming) are associated with each Serial Number stored in our cloud-based secure database. QAT consists of visual part inspection as well as verification of all critical parameters and performance of each part. For the CWDM-SFP-xxxx-FL optical output power and wavelength (1470-1610nm) are verified on optical spectrum analyzers. Receiver sensitivity is verified at both minimum distance and the 80km maximum range over actual (not simulated) SMF , singlemode fiber cable. Digital Diagnostics Monitoring (DDM) parameters including: optical output power, receive optical power, internal module temperature, transmit bias current and supply voltage, are tested for compliance with specifications. In addition, the part is verified for proper operation across its full operating temperature range, 0C to 50C.



Q:What is the difference between SFP+ optical module and SFP optical module?

The volume of SFP and SFP+ optical modules is basically the same, and the main difference is the transmission rate. The maximum transmission rate of SFP optical modules is 2.5Gb/s, while that of SFP+ optical modules is 10Gb/s. Due to the different transmission rates, their applications and transmission distances will vary.

Q:Can SFP+ optical modules be used in SFP ports?

Yes. 10G SFP+ optical modules can work when inserted in SFP ports, but the transmission rate is only 1Gbps; however, SFP optical modules cannot be used in SFP+ ports.

Q:What is the longest transmission distance supported by SFP+ optical modules?

Depending on the type of fiber used, the transmission distance is also different. The transmission distance is 300 meters when used with OM1 multi-mode fiber, and the longest distance, when used with OS2 single-mode fiber, is currently 120 kilometers.

Q:Can SFP+ optical modules be used with SFP+/QSFP high-speed cables?

Can't. The SFP+/QSFP high-speed cable can be directly inserted into the SFP+/QSFP port of the switch to connect the switches at both ends without using optical modules.

Q:Will SFP+ optics automatically configure between 1GbE and 10GbE?

Auto configuration is not supported between 10GE and 1GE rates.

Coarse Wavelength-Division Multiplexing (CWDM) Small Form-Factor Pluggable (SFP) solution allows enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fiber Channel in campus, data-center, and metropolitan-area access networks. 1.25Gbps and 2.5Gbps CWDM SFP transceivers are high-performance, cost-effective modules supporting 40km, 80km and 120km transmission distance with single mode fiber (SMF) via wavelength of 1270nm to 1610nm. 10G CWDM SFP+ Transceivers and 10G CWDM XFP transceivers are designed for 10GBASE-LR/ER/ZR applications achieve the transmission from 10km up to 80km.
