There are many types of fiber optic transceivers: 100 Mbps, single fiber and dual fiber, one optical and one electrical to one optical and eight electrical, and box rack type. In fact, the decision-making chain is very short. After asking five questions, the model is basically locked. This article organizes these five steps into a tickable list that can be used directly in both procurement and design.

Questions 1 and 2: How much traffic is running and how many fibers are there?

The speed is determined based on the total peak traffic of the terminal equipment and a 30% margin is left: 100 Mbit for light traffic such as access control sensors, 1 Gigabit for monitoring aggregation and uplink. If you are not sure, just go to 1 Gigabit. The price difference between the two rates is far less than the cost of replacing the entire batch later. The number of fiber cores determines whether it is single fiber or dual fiber: there are no less than two optical fibers available and there is no rental fee. Choosing dual fiber is cheaper and easier to repair; if there is only one core, choose single fiber, but the price is that it must be purchased and managed in pairs.

The third and fourth questions: How many terminals and how to pair the two ends?

To connect one optical cable to one device, choose one optical and one electrical device; to hang multiple light traffic devices, choose one optical cable and four electrical devices. Please refer to100M single-mode dual-fiber one-optical four-electrical fiber optic transceiverport allocation to estimate. If you choose a single fiber, you must register the wavelength segment, and keep the A and B labels from the day of purchase to the day of scrapping, so that you can replace spare parts midway to avoid any pitfalls.

Question 5: Should it be installed in a weak current room or in a cabinet?

The points are scattered and there are few links. Box-type equipment is the most flexible to hang on the wall. If more than eight links are concentrated in a room, consider14-slot box transceiver rackUnify power supply and inspection. It is recommended to allocate enough slots at one time and leave two or three as spares. This saves labor compared with replacing racks in batches. If you still have one or two edge cases left after completing the five steps, please send the link diagram and point table to EB-LINK technical support for verification. Call 0755-83179002. Regular configuration can be returned on the same day.
