PoE fiber optic transceivers usually have three application types: fiber to IP camera, fiber to wireless AP, and fiber to desktop. Before the installation starts, please make sure to prepare the following items: a Gigabit Ethernet switch, a 10/100/1000 M PoE power supply optical fiber transceiver, an IP camera, two SFP Gigabit optical modules, one Network cable (such as Cat5e/Cat6), an optical fiber jumper (such as OS2/OM4).
Step 1: Insert two SFP Gigabit optical modules into the optical ports of the PoE optical fiber transceiver and the SFP ports of the switch respectively.
Step 2: Connect one end of the optical fiber jumper to the SFP optical module of the PoE optical transceiver, and the other end to the SFP optical module of the switch.
The third step: Finally, use an unshielded twisted pair to connect the electrical port of the IP camera and the PoE optical fiber transceiver.
How to choose a PoE fiber optic transceiver that best suits your network needs? Usually can be considered from the following aspects:
Speed: The speed of the PoE fiber optic transceiver is the primary consideration. There are currently five types of PoE-powered fiber optic transceivers on the market: 10M, 100M, 1000M, 10/100M, 10/100/1000M.
Port type and quantity: Most PoE fiber optic transceivers are equipped with one optical port and one electrical port, but some PoE fiber optic transceivers have multiple ports, such as 1-2 optical ports and 4 electrical ports.
Single-mode/multi-mode: According to the different transmission media, PoE fiber optic transceivers have two types: single-mode fiber transceiver and multi-mode fiber transceiver. The transmission mode is different, the corresponding transmission distance and the optical module that can be used together are also different.
Duplex mode: As some PoE fiber optic transceivers can only be used as duplex mode and cannot be used as half-duplex mode, data packet loss may occur when this power supply transceiver is connected to a switch or hub that only supports half-duplex mode The phenomenon. So please make sure that the PoE transceiver you buy can support both duplex mode and half-duplex mode.
Working temperature: If you need to buy an industrial-grade PoE fiber optic transceiver, you need to pay special attention to check whether the fiber optic transceiver you are buying can operate at a wide temperature (-20℃~+70℃) or ultra-wide Work in the temperature range (-40℃~+90℃).
Support standards: Generally, PoE optical fiber transceivers conform to the three PoE standards of IEEE802.3af, IEEE802.3at or IEEE802.3bt. Before purchasing, please confirm whether the PoE fiber optic transceiver supports the three PoE standards mentioned above, otherwise there may be related problems such as device incompatibility when using it.
