1 Compact SFP Bi-Directional Transceiver Module for Gigabit Ethernet FEATURES RoHS compliant Compact SFP MSA compliant Support Digital Diagnostic Function 2 channels Bi-direction optical transceiver LC connector with 1310nm Transmitter and 14900nm Receiver Single + 3.3V power supply and TTL logic interface CSFP Standard Option 2 Description The CSFP-33-xxxxx is hot pluggable 3.3V Small-Form-Factor (SFP) 2 channels Bi-Directional transceiver module designed expressly for high-speed communication applications that require rates of up to 1250Mbit/sec. It is compliant with the Gigabit Ethernet standards, as well as the CSFP Multisource Agreement (MSA). The CSFP-33-xxxxx transceivers provide with the LC receptacle that is compatible with the industry standard LC connector. The module includes un-cool DFB laser, InGaAs PIN, Preamplifer and WDM filter in a high-integrated optical assembly for high-density system application. The CSFP Bi-Directional transceiver can upgrade transmission capacity very convenient without installing new fibers. Application IEEE 802.3ah 1000BASE-BX Gigabit Ethernet Application FTTx WDM Broadband Access Switch to switch/backbone interface Performance Data link up to 20km in 9/125um single mode fiber. 1 Revision: S0
