FiberMania provides OEM and customized manufacturing services for copper SFP transceiver modules. Customization options can include host interface configuration, EEPROM coding, equipment compatibility, product labeling, housing identification, packaging, and other project-specific requirements.

For B2B deployments, customers can provide the target switch, router, or network equipment model for compatibility evaluation. Customized coding and identification can be prepared for equipment-specific deployments, helping simplify integration into existing network platforms.

Q1. Why use an RJ45 SFP module instead of a built-in copper port?

An RJ45 SFP module allows a device with an available SFP slot to gain copper Ethernet connectivity without replacing the network equipment. This provides greater flexibility when a switch or router has a combination of fiber SFP ports and copper connectivity requirements.

Q2. Can this module automatically work at both 10Mbps and 100Mbps?

The module is designed for 10/100Mbps Fast Ethernet operation, allowing compatible equipment to establish links at the supported speed according to the connected network and host configuration. The actual negotiated speed also depends on the capabilities and configuration of the equipment at the other end.

Q3. What type of cable can be used for the 100m connection?

The module is designed for standard twisted-pair copper Ethernet cabling. The actual supported distance depends on the cable category, installation quality, connector condition, electromagnetic environment, and the requirements of the connected Ethernet equipment.

Q4. What is the purpose of the SGMII host interface?

SGMII provides the electrical connection between the copper SFP module and the host equipment. It carries the Ethernet data between the module’s PHY circuitry and the host system, allowing the RJ45 copper interface to be integrated through an SFP slot.

Q5. What do TX Disable and RX Loss of Signal provide?

TX Disable allows the host system to control or disable the module’s transmitter when required. RX Loss of Signal provides an indication when the module does not detect an expected incoming signal, which can assist with link status monitoring and troubleshooting.

Q6. Can the module be used in a switch from a specific manufacturer?

Compatibility depends on the SFP interface, host electrical requirements, firmware, and transceiver identification settings of the network equipment. FiberMania can provide customized EEPROM coding or host identification for qualified B2B projects after the target equipment model is provided.
