SGMII 100BASE FX SFP

What is SGMII?

The SGMII (Serial Gigabit Media Independent Interface) is a supplement of MII, a standard interface used to connect an Ethernet MAC-block to a PHY. It is utilised for Gigabit Ethernet (contrary to Ethernet 10/100 for MII). It differs from GMII by its low-power and low pin count serial interface (commonly referred to as a SerDes). To carry frame data and link rate information between a 10/100/1000 PHY and an Ethernet MAC, SGMII uses a differential pair for data signals and for clocking signals, with both being present in each direction (i.e., transmit and receive), giving 8 signal lines in total.

Brief introduction of SGMII SFP Transceiver

SGMII SFP is designed for 100BASE-FX and 100BASE-LX applications of 2km/10km with SMF. The transceiver consists of two sections: The standard SFP part and the PHY part built with SGMII interface. The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner.
