      Disclosed herein are systems, devices, and methods for improving the technology related to matching supply-side users with demand-side users in a marketplace. An opportunity matching platform may receive one or more business opportunities created by one or more demand-side users and then provide the one or more business opportunities to a plurality of supply-side client stations. In turn, each supply-side client station may present the one or more business opportunities to a respective supply-side users, receive the user's feedback on the one or more business opportunities, and then provide the feedback data for the supply-side user back to the opportunity matching platform. Thereafter, the opportunity matching platform may process the supply-side user feedback data and then provide various information to the demand-side users and/or supply -side users that help such users reach agreement on opportunities.

      • How to Select Patch Cable for Optical TransceiverHow to Select Patch Cable for Optical Transceiver

          People are always amazed by the development of optical communication. Things move really fast in this industry. Fiber optic transceiver, a small-size but important optical component, can best represent the advancing of the optical communication industry. The form factor of optical transceivers has changed from GBIC for Gigabit Ethernet to SFP+ for 10GbE, QSFP+ for 40GbE and 100G CFP and QSFP28. Even a double density QSFP—QSFP-DD for 200/400GbE is under research. It’s not difficult to recognize all these different types of fiber optic transceivers. However, customer could be confused about how to connect these transceiver to the telecommunication network. This post will introduce how to select patch cables for optical transceivers in details.

          Patch Cable Selection Guide
          To select the right patch cable for your modules, you should firstly have a comprehensive understanding of the modules mainly from the following aspects: transmission media, interface, transmission distances and data rate.
