The 1.25G SFP transceiver module

SOPTO 1.25G SFP optic transceiver module is suitable for the application of fiber optical communication whose data rate is less than 1.25G. The 1.25G SFP transceiver module integrates the receiving and transmitting circuits with full metal jacket, plastic tail plug shell and LC interface.


Gigabit SFP transceiver


The 1.25G SFP optical transceiver module has the function of hot-pluggable, which can be plugged and pulled out in the case of the continuous power supply. The 1.25G SFP transceiver module is suitable for the metropolitan area network.


SOPTO offers other SFP module with different data rates, such as 2.5G SFP module, 4G SFP optic transceiver module, etc. In addition, there are many types of SFP modules with different working wavelength and transmission distance for customers.

Distance of 1310nm CWDM SFP+ transceiver and 1550nm CWDM SFP+ transcveiver

After double checked with our engineers about the 1510nm SFP+ CWDM Transceivers. The shortest distance for SFP+ 10G, CWDM, 1510nm is 40km. Normally, we provide 10km ones for 8 channels wavelength around 1310nm. If you want 1510nm 10km ones, we also can provide, bur for specific made. Can you SFP+ Cable work with one side for HP and the other side for Exterme? Re: So can you tell me whether they are working on HP DL380G7 Card HP FC1242SR 4Gb PCI-E DC HBA  Part number AE312A? According to our experience, if you used them on HP server or HBA cards, the one which i provided ( to) you should be compatible with them.   I have double checked with our engineer about the HP compatible fiber

Is it possible to install in your fast connector

Q: For the project I will use flat drop fiber cable 8mm, is it possible to install in your fast connector? Re: Usually we install 5mm flat drop cable in our fast connector. For the flat drop fiber cable of 8mm, it has catenary wire, because of the diameter is bigger than entry port, so it's hard to install.

Inspection Service

Is it possible that we ourselves learn how to make Inspection Service, which we can create a service center in our country, because I think it will be important for our customers? Re: We agree with you the best quality and after-sales service for customers is the basis of expanding our business. We’ve been dedicated to customer-oriented service and the development of trustworthy relationship, so we could do our products have been tested rigorously before shipments.
