The S155 series are hot pluggable 3.3 V Small-Form-Factor (SFP) duplex and Bi-Directional transceiver module designed expressly for highspeed communication applications that require rates of up to 155 Mbps. It is compliant with the Fast Ethernet, ATM, SONET OC-3/SDH STM-1 standards, as well as the SFP Multisource Agreement (MSA). The S155 transceivers provide with the LC receptacle that is compatible with the industry standard LC connector. The transceiver is also compatible with industry standard RFT connector and cage. It also includes a LOS (Loss Of Signal) circuit that provides a LVTTL logic-high output when an unusable optical signal level is detected.
The Bi-Directional module includes 1310 or 1550 nm un-cool FP laser, InGaAs PIN, Preamplifer and WDM filter in a high-integrated optical assembly for high-density system application. The SFP BiDirectional transceiver can upgrade transmission capacity very convenient without installing new fibers.
