The 1.25Gbps SFP Optical Transceiver is a robust and efficient module designed for long-distance optical communication over single-mode fiber (SMF) up to 80 kilometers. It is housed in a compact SFP package with an LC connector and utilizes a 1550nm DFB laser and PIN photodetector for reliable and high-quality performance. This transceiver supports data rates of up to 1.25Gbps, making it suitable for Ethernet, telecom, and Fiber Channel applications. With a single +3.3V power supply and LVPECL-compatible data input/output interface, it offers seamless integration with various networking systems. Its compliance with IEC-60825 laser safety standards and RoHS regulations underscores its commitment to safety and environmental responsibility.
The transceiver operates efficiently under a range of environmental conditions, with a supply voltage range of 3.15V to 3.45V and operational temperatures from 0Ā°C to +70Ā°C for commercial applications and -40Ā°C to +85Ā°C for industrial use. Its maximum power dissipation of 1W ensures energy efficiency. Additionally, the module is equipped with strong protection against electromagnetic interference (EMI) and electrostatic discharge (ESD), ensuring stable operation even in challenging network environments.
Optically, the transceiver’s transmitter operates at a center wavelength of 1550nm, delivering output power ranging from 0dBm to +5dBm with an extinction ratio of 10dB to 15dB, ensuring clear signal transmission. The receiver accommodates wavelengths from 1260nm to 1620nm, offering a sensitivity of -24dBm and an overload threshold of 0dBm. These specifications meet IEEE 802.3z and ANSI Fiber Channel standards, ensuring compatibility with modern networking protocols and reliable performance.
The transceiver also boasts advanced electrical features, including a differential impedance of 100Ī© and support for input swing differentials between 500mV and 2400mV. The receiver provides an output swing differential from 370mV to 2000mV. Additional functionalities, such as TX Disable, TX Fault, and Loss of Signal (LOS) detection, enable precise control and fault monitoring, enhancing its usability in complex network setups.
In summary, the 1.25Gbps SFP Optical Transceiver is a high-performance and energy-efficient solution for long-distance networking applications. Its advanced optical and electrical performance, coupled with compliance to international standards, makes it an ideal choice for modern telecommunications and data networking infrastructure.
The CT-SFP-ZX is a hot-pluggable SFP transceiver designed for 1.25 Gb/s optical links over single-mode fiber up to 80 km. It integrates a 1550 nm DFB laser transmitter with a PIN photodiode receiver, offering reliable optical performance with moderate sensitivity (ā24 dBm) and extended reach. Operating with a single +3.3 V supply and <1 W power dissipation, the module supports LVPECL-compatible differential I/O, EEPROM-based digital diagnostics, and strong EMI/ESD protection. Fully compliant with IEEE 802.3z Gigabit Ethernet, ANSI Fibre Channel, IEC-60825 Class 1 laser safety, and RoHS, it is suitable for both commercial and industrial applications.
