SGMII SFP Providing Gigabit Ethernet to Fast Ethernet Conversion Jun 1, 2009

SGMII SFP is used to connect Gigabit Ethernet to Fast Ethernet, such as between switch and switch interface, switched backplane applications and router/service interface.

SGMII SFP transceiver is high performance, cost effective modules. It is designed for 100BASE-LX applications of 10km with SMF. The sfp 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. The system can also get the LOS (or link)/Disable/Fault information via I2C register access.
