MikroTik compatible S+85DLC03D Description
S+85DLC03D is MikroTik's 10GBASE-SR SFP+ transceiver, commonly deployed in CRS3xx, CRS5xx, CCR2004, and RB5009 platforms running RouterOS or SwOS. EdgeOptic's compatible version replicates the original optical and electrical parameters: 850 nm VCSEL transmitter, PIN photodiode receiver, duplex LC/UPC connector, and 6.1 dB minimum link budget for 300 m on OM3 or 400 m on OM4 multimode fiber. The module conforms to IEEE 802.3ae 10GBASE-SR.
Multi-rate support covers 1.25 Gbps (GbE) through 9.95 Gbps (STM-64) to 10.3125 Gbps (10GbE), with the negotiated speed depending on host port and RouterOS interface configuration. CRS3xx SFP+ cage ports support both 1G and 10G negotiation, so this module can also serve GbE uplinks when the port speed is set to 1G in RouterOS. DDM/DOM is enabled and readable through the RouterOS "/interface ethernet monitor" command, showing Tx/Rx power in dBm, module temperature, bias current, and supply voltage. The SFP+ form factor follows SFF-8431/SFF-8432 MSA. Operating temperature range is 0°C to 70°C.
MikroTik RouterOS does not enforce vendor-locked EEPROM checks the way enterprise switch vendors do, which means third-party SFP+ modules generally work without warnings. EdgeOptic still programs the compatible with MikroTik-specific vendor identification to ensure clean reporting in the RouterOS interface list and accurate DDM readouts. The S+85DLC03D is a popular choice for WISP and small data center backbone links where MikroTik CRS switches aggregate 10G fiber uplinks from access layer equipment.
CE/RoHS certified and compliant with the SFP+ MSA per SFF-8431. For RouterOS deployment questions or bulk MikroTik SFP+ orders, contact our sales team.
Frequently Asked Questions
Does the S+85DLC03D work in CRS3xx switches at 1G speed?
Yes. MikroTik CRS3xx SFP+ ports accept either 1G SFP or 10G SFP+ modules based on the inserted module type. The S+85DLC03D compatible can operate at 1.25 Gbps when the port is configured for 1G mode in RouterOS, though 10G is the default and primary intended rate.
How do I read S+85DLC03D DDM values in RouterOS?
In RouterOS terminal, use "/interface ethernet monitor [interface-name]" to display real-time SFP+ diagnostics including Tx/Rx optical power (dBm), module temperature, laser bias current, and supply voltage. These readings update dynamically and can be used for link troubleshooting.
