MikroTik SFP/SFP+/SFP28/QSFP+/QSFP28 compatibility
This article shows the compatibility of MikroTik devices with SFP, SFP+, SFP28, QSFP+, and QSFP28 transceivers. It features detailed compatibility tables that provide valuable insights into which transceivers are suitable for use with MikroTik devices. Additionally, some practical configuration examples are provided using the RouterOS CLI to set different data transmission rates. For more detailed descriptions of properties, please refer to the Ethernet user manual.
MikroTik devices and SFP, SFP+, SFP28, QSFP+, and QSFP28 modules do not have any restrictions for other vendor equipment.
While MikroTik cannot ensure full compatibility with modules from all manufacturers, as long as the other vendor modules and devices comply with transceiver multi-source agreement (MSA) they should be compatible with MikroTik.
RouterOS uses a disabled FEC mode as the default setting for SFP28 and QSFP28 interfaces. To ensure a successful link with other vendor devices, you may need to enable FEC mode by configuring it to either fec74
or fec91
. For more information please refer to the Ethernet user manual.

SFP+ interface compatibility with 1G optical transceivers
For MikroTik devices with SFP+ interface that support both 10G and 1G link rate, following settings must be set on both linked devices for required interfaces. These settings only relate when optical SFP transceivers are used. In order to get them working in 1G link rate, use the following configuration:
# Since RouterOS v7.12 /interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=1G-baseX # Older RouterOS /interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=1Gbps full-duplex=yes
- auto-negotiation disabled
- port speed 1G
- full-duplex

SFP+ interface compatibility with 10G/25G optical transceivers
MikroTik devices with SFP+ ports can establish 10G links using 10G/25G optical fiber transceivers, however additional SFP Rate Select setting must be configured to avoid data corruption during transmission. The following settings are required on the SFP+ interface:
# Since RouterOS v7.12 /interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=10G-baseSR-LR sfp-rate-select=low # Older RouterOS /interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=10Gbps full-duplex=yes sfp-rate-select=low
This requirement applies to MikroTik 10G/25G modules:
- XS+31LC10D
- XS+2733LC15D
SFP+/SFP28 interface compatibility with 2.5G transceivers
The 2.5G link rate support is implemented since RouterOS v7.3. MikroTik devices with SFP+ and SFP28 interfaces that support 2.5G link rate require following settings to be set on both linked device interfaces.
# Since RouterOS v7.12 /interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=2.5G-baseX # Older RouterOS /interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=2.5Gbps full-duplex=yes

QSFP+/QSFP28 interface supported link rates
In RouterOS, QSFP+ and QSFP28 interfaces are designed to handle high-speed data transmission by utilizing multiple channels. Each QSFP+ or QSFP28 interface is divided into four sub-interfaces, each corresponding to a transmission channel necessary for proper operation.
The naming convention for QSFP+ and QSFP28 sub-interfaces includes two parts:
- The first digit following "qsfpplus" or "qsfp28-" represents the QSFP+ or QSFP28 physical interface.
- The second digit, ranging from 1 to 4, denotes each of the individual channels.
Below are examples of how QSFP+ and QSFP28 interfaces appear in RouterOS:
# QSFP+ /interface ethernet print Flags: R - RUNNING Columns: NAME, MTU, MAC-ADDRESS, ARP, SWITCH # NAME MTU MAC-ADDRESS ARP SWITCH 1 qsfpplus1-1 1500 48:8F:5A:B6:09:8C enabled switch1 2 qsfpplus1-2 1500 48:8F:5A:B6:09:8D enabled switch1 3 qsfpplus1-3 1500 48:8F:5A:B6:09:8E enabled switch1 4 qsfpplus1-4 1500 48:8F:5A:B6:09:8F enabled switch1 # QSFP28 /interface ethernet print Flags: R - RUNNING Columns: NAME, MTU, MAC-ADDRESS, ARP, SWITCH # NAME MTU MAC-ADDRESS ARP SWITCH 1 qsfp28-1-1 1500 DC:2C:6E:9E:11:14 enabled switch1 2 qsfp28-1-2 1500 DC:2C:6E:9E:11:15 enabled switch1 3 qsfp28-1-3 1500 DC:2C:6E:9E:11:16 enabled switch1 4 qsfp28-1-4 1500 DC:2C:6E:9E:11:17 enabled switch1
Configuration and monitoring for these sub-interfaces may vary based on factors such as auto-negotiation, advertised speeds, and the type of transceiver (e.g., break-out cable or single fiber). The following sections will provide guidance on the configuration necessary for each use case.
Disabling or enabling any of the four sub-interfaces will trigger a reconfiguration of the entire port group, restarting all four channels.
QSFP+
For MikroTik CRS3xx series devices, QSFP+ interfaces support the following link speeds:
- 1x 40G
- 4x 10G
- 4x 1G
Link Configuration:
- 40G: Can be configured with either auto-negotiation or a forced 40G speed.
- 4x10G and 4x1G: Must be set with a forced speed mode and auto-negotiation disabled.
Starting from RouterOS version 7.12, in addition to choosing the right transmission rate, it's important to specify the correct link mode. For example, you might use CR4 for DAC(Direct Attach Copper) or SR4-LR4 for optical fiber.
Configuration Examples:
For RouterOS v7.12 and later:
# 1x40G - DAC /interface ethernet set qsfpplus1-1 auto-negotiation=no speed=40G-baseCR4 # 1x40G - Optical /interface ethernet set qsfpplus1-1 auto-negotiation=no speed=40G-baseSR4-LR4 # 4x10G - DAC /interface ethernet set qsfpplus1-1 auto-negotiation=no speed=10G-baseCR /interface ethernet set qsfpplus1-2 auto-negotiation=no speed=10G-baseCR /interface ethernet set qsfpplus1-3 auto-negotiation=no speed=10G-baseCR /interface ethernet set qsfpplus1-4 auto-negotiation=no speed=10G-baseCR # 4x10G - Optical /interface ethernet set qsfpplus1-1 auto-negotiation=no speed=10G-baseSR-LR /interface ethernet set qsfpplus1-2 auto-negotiation=no speed=10G-baseSR-LR /interface ethernet set qsfpplus1-3 auto-negotiation=no speed=10G-baseSR-LR /interface ethernet set qsfpplus1-4 auto-negotiation=no speed=10G-baseSR-LR
In single-link mode, only the first QSFP+ sub-interface needs to be configured, while the remaining sub-interfaces should remain enabled.
For RouterOS versions earlier than v7.12:
# 1x40G - DAC/Optical /interface ethernet set qsfpplus1-1 auto-negotiation=no speed=40Gbps full-duplex=yes # 4x10G - DAC/Optical /interface ethernet set qsfpplus1-1 auto-negotiation=no speed=10Gbps full-duplex=yes /interface ethernet set qsfpplus1-2 auto-negotiation=no speed=10Gbps full-duplex=yes /interface ethernet set qsfpplus1-3 auto-negotiation=no speed=10Gbps full-duplex=yes /interface ethernet set qsfpplus1-4 auto-negotiation=no speed=10Gbps full-duplex=yes
QSFP28
For MikroTik CRS5xx series and CCR2216 devices, QSFP28 interfaces support the following link speeds:
- 1x 100G
- 2x 50G (available since RouterOS v7.12)
- 1x 40G
- 4x 25G
- 4x 10G
- 4x 1G
Not supported: 1x 50G, 2x 40G
Link Configuration:
- 100G: Can be configured with either auto-negotiation or a forced 100G speed.
- 2x50G, 1x40G, 4x25G, 4x10G, and 4x1G: Must be set with a forced speed mode and auto-negotiation disabled.
Starting from RouterOS version 7.12, in addition to choosing the right transmission rate, it's important to specify the correct link mode. For example, you might use CR4 for DAC(Direct Attach Copper) or SR4-LR4 for optical fiber.
Configuration Examples:
For RouterOS v7.12 and later:
# 1x100G - DAC /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=100G-baseCR4 # 1x100G - Optical /interface ethernet set qsfp28-2-1 auto-negotiation=no speed=100G-baseSR4-LR4 # 2x50G - DAC /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=50G-baseCR2 /interface ethernet set qsfp28-1-3 auto-negotiation=no speed=50G-baseCR2 # 2x50G - Optical /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=50G-baseSR2-LR2 /interface ethernet set qsfp28-1-3 auto-negotiation=no speed=50G-baseSR2-LR2 # 4x25G - DAC /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=25G-baseCR /interface ethernet set qsfp28-1-2 auto-negotiation=no speed=25G-baseCR /interface ethernet set qsfp28-1-3 auto-negotiation=no speed=25G-baseCR /interface ethernet set qsfp28-1-4 auto-negotiation=no speed=25G-baseCR # 4x25G - Optical /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=25G-baseSR-LR /interface ethernet set qsfp28-1-2 auto-negotiation=no speed=25G-baseSR-LR /interface ethernet set qsfp28-1-3 auto-negotiation=no speed=25G-baseSR-LR /interface ethernet set qsfp28-1-4 auto-negotiation=no speed=25G-baseSR-LR
In single-link mode, only the first QSFP28 sub-interface needs to be configured, while the remaining sub-interfaces should remain enabled. Similarly, for 2x50G link mode, only the master interfaces (e.g., qsfp28-1-1 and qsfp28-1-3) need to be configured, but the other sub-interfaces must remain enabled.
For RouterOS versions earlier than v7.12:
# 1x100G - DAC/Optical /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=100Gbps full-duplex=yes # 4x25G - DAC/Optical /interface ethernet set qsfp28-1-1 auto-negotiation=no speed=25Gbps full-duplex=yes /interface ethernet set qsfp28-1-2 auto-negotiation=no speed=25Gbps full-duplex=yes /interface ethernet set qsfp28-1-3 auto-negotiation=no speed=25Gbps full-duplex=yes /interface ethernet set qsfp28-1-4 auto-negotiation=no speed=25Gbps full-duplex=yes
QSFP+/QSFP28 interface compatibility with breakout cables
