FJYF2 is a highly integrated Center/ Terminal MC (Media Converter) for FTTH (Fiber-To-The-Home) on both Terminal side (CPE option) and Network side (CO option). The FJYF2 is designed specifically for TTC TS-1000 Spec that satisfies 5 ways of loop-back tests.

The FJYF2 supports multiple interfaces (C_Mode1, 2, 3 & 4) in order for any specific application to do additional functions. In C_Mode1, it equipped with 2 MII ports; In C_Mode2 it integrates one 10/100Base-TX and one 100Base-FX transceivers. They operate at chip mode selection. Both have embedded packet memory, a switch controller and OAM (Operation, Administration, and Maintenance)   control logic into a single CMOS integrated circuit. In C_Mode1 each MII port may optionally connect to a 100Base-FX fiber-optic transceiver or a twisted-pair transceiver. In C_Mode2 may optionally connect to an O/E module or a transformer.

The FJYF2 provides 10/100 auto-negotiation capability for 10/100Base-TX ports. Only 10/100Base-TX port could support Full-Duplex and Half-Duplex modes. In half-duplex mode, the controller supports back-pressure congestion control to avoid packet loss during a long burst of traffic. In full-duplex mode of operation, The FJYF2 supports symmetric IEEE802.3x flow control. With hardware switching engine, The FJYF2 can switch at Full-Duplex wire rate. Totally 1K MAC addresses filtering and aging function are supported.
