The 155Mbps Bi-Directional SFP Optical Transceiver is a reliable and efficient solution for medium-distance communication over single-mode fiber (SMF) up to 20 kilometers. This transceiver is offered in two configurations: a 1310nm FP laser with a 1550nm PIN photodetector or a 1550nm FP laser with a 1310nm PIN photodetector, depending on the specific application needs. Compliant with industry standards, including IEC-60825 laser safety and RoHS regulations, the module is optimized for Ethernet, telecom, and Fiber Channel applications. It features a compact SFP package with an LC connector, operating on a single +3.3V power supply to ensure energy efficiency.
The transceiver delivers robust optical performance with an output power range of -15dBm to -8dBm for both transmitter configurations, paired with a receiver sensitivity of -34dBm to support reliable signal reception. It includes advanced features such as Loss of Signal (LOS) detection and LVPECL-compatible data input/output interfaces, offering enhanced diagnostics and operational control. With a power dissipation of just 1W, the module supports a commercial operating temperature range of 0°C to +70°C, with options available for industrial-grade performance between -40°C and +85°C. This combination of features makes it a dependable choice for high-speed optical communication systems in diverse environments.
The CT-MSFP-BX-20U and CT-MSFP-BX-20D are cost-effective hot-pluggable SFP modules for 155 Mb/s bidirectional links up to 20 km on 9/125 μm SMF. Using 1310 nm (U) or 1550 nm (D) FP transmitters with complementary PIN photodiode receivers, they deliver reliable optical connectivity for short-to-medium reach deployments. Operating from a single +3.3 V supply with <1 W maximum power dissipation, the modules support LVPECL-compatible electrical interfaces, EEPROM digital diagnostics, and robust EMI/ESD protection. Fully compliant with IEC-60825 Class 1 laser safety and RoHS standards, they are available in both commercial and industrial temperature grades.
