The most time-consuming thing when choosing a model is often not remembering which gears are available. EB-LINK compiles the common specifications of optical modules, optical fiber transceivers and high-speed cables in the station into a quick checklist. It first creates a stall map and then narrows it down to specific models according to link conditions.
Optical modules are divided into four segments according to speed
| speed file | Site representative specifications | Common usage |
|---|---|---|
| 100M | Single mode dual fiber 20KM | Old equipment and low-speed collection |
| Gigabit | Single mode 10KM, multimode dual fiber, electrical port | Monitoring points and access layer |
| 2.5G | Single mode 20KM, 40KM, 80KM | Bandwidth tight convergence |
| 10G SFP+ | Multimode Dual Fiber, Singlemode 10 and 40km | Uplink and server access |
Among the four segments, long distances are only concentrated in 2.5G and 10 Gigabit. It is normal that models over 40 kilometers cannot be found in the 100 Mbps and Gigabit segments. When long distance is required, it is usually necessary to change the speed gear or adjust the network structure, rather than looking for the specifications with the same name in place.
Transceiver depends on port combination and fiber core occupation
Both are Gigabit, one optical and one electrical solution solve point-to-point, one optical and multiple electrical is to save fiber core; the difference between single fiber and dual fiber lies in the fiber core resources rather than the speed.

High-speed cables and network cards are taken from the same file
DAC and AOC cover four segments of 10G, 25G, 40G and 100G and have branch specifications. The network card side ranges from 10G series toPCI-EX16 100G single optical port fiber optic network card (Intel E810 chip)Each has a corresponding optical port. When doing a quick check, the module, network card, and cable should be written at the same speed and mouth shape. Three different files are the most common order mismatch.
The purpose of this list is to determine the three directions of speed, distance and port within three minutes, and leave the remaining details to the parameters on the product page to check one by one. The list is updated every quarter with new models, and old gears are kept marked to facilitate comparison of equipment in use.
