R&Q for 10G optical transceiver

  • December 06. 2017
The 10G optical module is an optical module that can transmit 10G information per second. There may be some questions when using 10G modules. Today we will list some typical questions and tell you the answers.

1.What is the difference between the SFP+ and the SFP optical module?
The size of SFP and SFP+ modules is the same, the main difference is the data rate. The maximum data rate of SFP module is 2.5Gb/s, while SFP+ module is 10Gb/s. Because the data rate is difference, the application and transmission distance are also different.

2.Can I use the SFP+ optical module on the SFP port?
Yes. The SFP+ optical module can be inserted into the SFP port to work, but the transmission rate is only 1Gbps; But SFP optical module can not be used in the SFP+ port.

3.What is the longest transmission distance supported by the SFP+ optical module?
According to the different kinds of fiber, the transmission distance is different, the transmission distance is 300m when using with OM3 multimode fiber and 100KM when using with OS2 single mode fiber.


4.Will the SFP+ optical module be configured automatically between 1GbE and 10GbE?
Automatic configuration is not supported between 10GE and 1GE rates.

5.Is TwinX and Twinax the same?
Yes, they are the same.


6.Can the SFP+ optical module be used with the SFP+/QSFP high-speed cable?
No. The SFP+/QSFP high-speed cable can be inserted directly into the SFP+/QSFP port of the switch, connecting the switches at both ends, no need to use optical transceiver.

7.Can ETU-Link's SFP+ high-speed cable be used on CISCO or other third party switches?

ETU-Link provides SFP+ high-speed cable compatible with CISCO and other brand switches.

The following picture shows that our professional testers test the compatibility of each optical module to ensure that our customers can receive high quality optical modules.

ETU-Link provides high-quality 10G Direct Attach Cable, can compatible with Cisco, Juniper, HP, ZTE and other major brand switches. The transmission distance supported by these products ranges from 0.5m to 7m. For more information, please visit our website: www.etulinktechnology.com.
