      GPON OLT Module (GPON Class C++)

      1. Pay attention to whether the wavelengths and transmission distances of the optical modules used by the switches at both ends are the same, as well as single-fiber dual-fiber, single-mode multi-mode problems. If the two ends are not equal, the corresponding converter should be used;

      2. When using the optical module, try to avoid static electricity and bumps. If bumps occur, it is not recommended to continue to use the optical module;

      3. Pay attention to the front and back of the optical module, and the tab and label should face upwards;

      4. When inserting the optical module into the switch, try to push it to the bottom as hard as possible. Generally, there will be a slight vibration. After inserting, you can gently pull out the optical module to check whether it is installed properly;

      5. When disassembling the optical module, first pull the wristband to a 90° position with the optical port, and then pull out the optical module.

      the SFP optical port?

      Now that Gigabit Ethernet has become popular in a large area, Gigabit Ethernet switches are also widely used in enterprise networks, optical access networks and other scenarios. Gigabit Ethernet has two port types, RJ45 and SFP ports, which can support the highest transmission rate of Gigabit, and are also backward compatible with the transmission rate of 10/100M.

      The RJ45 port is the built-in electrical port of the Gigabit Ethernet switch. The SFP port is the built-in optical port of the Gigabit Ethernet switch, so it cannot be directly connected by twisted pair or jumper. The following ETU-LINK will introduce the interconnection between the Gigabit RJ45 port and the SFP porat.

      To connect the gigabit RJ45 port and the SFP port, you can use the gigabit electrical port module of Yitianguang Communication, specification model: ES-T1-R, it is actually an interface converter, so it is also called an optical port to electrical port module. Insert the Gigabit electrical port module into the SFP optical port, and then connect the Category 6 network cable to the Gigabit RJ45 port.

      The Gigabit electrical port module is mainly used in the interconnection of the short-distance Gigabit RJ45 port and the SFP port. ES-T2-R), the longest transmission distance can be up to 100 meters using Category 6 twisted pair. In addition to the gigabit electrical port module, the electrical port module also has a 10 gigabit electrical port module, but the twisted pair connected to the 10 gigabit electrical port needs to be connected with a Cat6e or Cat7e network cable.

      The above is the method of connecting Gigabit RJ45 electrical port and SFP optical port introduced by ETU-LINK. Considering the cost of short-distance transmission, if the switch with SFP optical port uses optical module with optical fiber jumper Wire transmission will increase the cost, and the use of electrical port modules with Category 6 twisted pair cables is a low-cost transmission solution.
