The 1.25Gbps SFP Optical Transceiver is engineered for high-speed optical communication over single-mode fiber (SMF) up to 40 kilometers. This transceiver is housed in an SFP package with an LC connector, leveraging a 1310nm FP laser and PIN photo detector for reliable data transmission. It supports a data rate of 1.25Gbps, making it suitable for Ethernet, telecommunications, and Fiber Channel applications. The module operates on a single +3.3V power supply and features LVPECL-compatible data input/output interfaces, ensuring compatibility with a wide range of host systems. Its compliance with IEC-60825 laser safety standards and RoHS regulations underscores its commitment to safety and environmental responsibility.
Designed for diverse operational environments, the transceiver functions effectively within a supply voltage range of 3.15V to 3.45V. It operates across commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges, with a maximum power dissipation of 1W. The transceiver’s low electromagnetic interference (EMI) and robust electrostatic discharge (ESD) protection ensure reliable performance in demanding conditions, making it a dependable choice for modern network infrastructures.
The optical performance of the transceiver is highlighted by its transmitter center wavelength of 1310nm, with an output power range of -5dBm to 0dBm. The extinction ratio between 10dB and 15dB ensures clear signal transmission. The receiver accommodates wavelengths from 1260nm to 1620nm, with a sensitivity of -24dBm and an overload threshold of 0dBm. This robust optical design adheres to IEEE 802.3z and ANSI Fiber Channel standards, ensuring high-quality signal integrity and protocol compatibility.
Electrically, the transceiver is engineered for versatility. It features a differential impedance of 100Ω and supports a data input swing differential of 500mV to 2400mV. The receiver section delivers a single-ended data output swing of 370mV to 2000mV. Control features such as TX Disable and TX Fault allow for precise operational management, while the Loss of Signal (LOS) detection provides fault monitoring capabilities.
Overall, the 1.25Gbps SFP Optical Transceiver combines advanced optical and electrical performance with energy efficiency and compliance with industry standards. Its design ensures reliable operation in various applications, making it a valuable component for high-speed networking solutions.
The CT-SFP-EX is a cost-effective hot-pluggable SFP transceiver designed for 1.25 Gb/s optical links up to 40 km on single-mode fiber. It integrates a 1310 nm FP laser transmitter with a PIN photodiode receiver, delivering reliable medium-range optical connectivity. Operating on a single +3.3 V supply with <1 W power consumption, the module provides LVPECL-compatible differential interfaces, EEPROM 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 standards, it is available in commercial and industrial temperature grades.
