1 OC-3 LC Duplex Pluggable SFP Transceiver RoHS Compliant DP02TI1 Product Features Up to 155Mbps optical data link RoHS compliant Digital diagnostic SFF-8472 compliant Digital diagnostics are external calibrated Uncooled 1310 FP LD transmitter Up to 20Km link distance Metal enclosure, low EMI Single 3.3V power supply Low power dissipation Optional operating case temperature : Tc - ST : -5~75 - ET : -20~85 - IT : -40~85 Applications SONET OC-3 / SDH STM-1 Product Overview The DP02TI1 of Small Form Factor Pluggable (SFP) transceiver module is specifically designed for high performance integrated duplex data link over single mode optical fiber. The high-speed laser diode and PD are provided as a light source and a detector, respectively. The DP02TI1 is designed for fiber optic analog/digital repeater applications. An EEPROM contained the detailed product information and digital diagnostics function for the host equipment is accessed by the 2-wire serial CMOS EEPROM protocol. It complies with SFP MSA, SONET/SDH standards, Class 1 laser products, EN60825, and EN The transmitter features ac-coupled differential data input, and an LVTTL for Tx disable input and Tx fault output. The receiver features differential ac-coupled data outputs and LVTTL for LOS output. Circuit ground is internally isolated from frame ground.
