This SFP transceiver is designed for 100BASE-FX applications, with built-in PHY device supporting SGMII interface (Serial Gigabit Media Independent Interface). The SGMII SFP transceiver consists of SFP part, the PHY part with both interfaced by SGMII.
The 100BASE-FX SGMII SFP module provides 100Mbp/s data link up to 2km on 50/125um multi-mode fibre. The SFP will auto-negotiate a 1000Mbp/S port to 100Mbp/s. In order to carry data link information between a 100/1000 PHY and an Ethernet MAC, SGMII uses a differential pair for data signals and for clocking signals. It is guaranteed to be 100% compatible with the OEM host switch, router or network interface card (NIC).
