S+RJ10 general guidance
Summary
MikroTik S+RJ10 is a unique 6-speed RJ-45 SFP+ module that is based on a Marvell 88X3310P transceiver. It offers up to 10 Gbps speeds using twisted-pair copper cables. All of the current MikroTik devices that have an SFP+ cage support the S+RJ10 module. This article serves as a guideline of the S+RJ10 usage in MikroTik devices with both passive or active cooling.
General Guidance
Product specification
The average power consumption of the transceiver is 2.7 W (10GBASE-T, 30 m link) which is relatively high comparing with S+85DLC03D optical module with maximum 0.8W power consumption. The operating temperature is 0 to +70 C, but the transceiver itself can heat up to 90 C.
S+RJ10 Positioning in devices
Due to high operating temperatures, it is recommended to use S+RJ10 transceivers while optical transceiver or an unused SFP+ interface is in between them. Take a look on the transceivers capable distance comparison table.
Using the S+RJ10 Side by Side or with passive cooling devices
There might be situations when it is not possible to use the recommended layout of the transceivers. In such cases where two or more S+RJ10 transceivers are plugged in beside one another or modules are used in passive cooling devices, the network administrator has to ensure additional cooling. The air flow around the device should be increased or the overall ambient temperature should be lowered to keep the temperature of the transceivers within the recommended range.
