It is common during network transformation that there are not enough ports or the peer device does not have optical ports. Rather than replacing the entire machine, it is better to make good use of SFP Gigabit electrical port modules and fiber optic transceivers to make use of the idle slots of existing equipment.
Electrical port module: convert SFP slot into RJ45
SFP Gigabit electrical port moduleConvert the SFP slot of the switch to a Gigabit electrical port, which is suitable for direct connection of short-distance copper cables to servers, NVR and other terminals, and can also be used for temporary interconnection testing in the computer room. It should be noted that the power consumption and heat generation of electrical port modules are higher than that of optical modules. Some platforms have an upper limit on the number of electrical port modules used at the same time. Check the device manual before centralized installation. Some old platforms also need to manually specify the rate in the port view. It is recommended to confirm the specific compatibility list with EB-LINK technical support to avoid idling the port after plugging in.
Transceiver: Provide links to points without optical ports
When the camera box and old equipment do not have an SFP slot, it is more economical to equip a pair of photoelectric conversion transceivers than to replace the switch. For use in convergence computer rooms14-slot box transceiver rackCentrally store more than a dozen optical fiber links to coordinateGigabit single mode dual fiber one optical one electrical fiber optic transceiverThe power supply is unified by the rack, which is much neater than collecting power at scattered points. It is also convenient for unified labeling and account creation.
Four points to note when using combinations
- The transceiver and module must have the same single-mode/multi-mode and distance specifications. Mixing and matching will not work.
- Combo ports and independent SFP slots are usually mutually exclusive. Please confirm the effective port before configuring.
- The transmission distance of the electrical port is limited, and it is recommended to use optical fiber for links exceeding tens of meters.
- The centralized power supply of the rack is only suitable for the computer room, and the outdoor box still uses an independent power supply.
The value of this type of transformation is to extend the life of existing equipment and compress the current budget. However, it is necessary to review the total bandwidth of the aggregation point and the lightning protection and grounding of the electrical port links. After the transformation is completed, the port ledger and spare parts library are updated simultaneously. The backbone and key links should not stay in the supplementary state for a long time.
