The 1.25Gbps SFP Optical Transceiver is an advanced module designed for ultra-long-range optical communication over single-mode fiber (SMF) up to 120 kilometers. It is housed in an SFP package with an LC connector and features a 1550nm DFB laser transmitter and an APD photodetector for superior performance. Supporting a data rate of 1.25Gbps, the transceiver is ideal for Ethernet, telecommunications, and Fiber Channel applications. Its LVPECL-compatible data input/output interface ensures easy integration with host systems, while its compliance with IEC-60825 laser safety standards and RoHS regulations highlights its safety and environmental reliability.
This transceiver is built to operate in diverse conditions, with a supply voltage range of 3.15V to 3.45V and support for both commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. Power dissipation is limited to 1W, ensuring energy efficiency. Additionally, the module offers low electromagnetic interference (EMI) and exceptional electrostatic discharge (ESD) protection, ensuring stable and reliable operation in demanding networking environments.
The optical performance of the transceiver is a key feature. The transmitter operates at a center wavelength of 1550nm with an optical output power range of 0dBm to +5dBm. The extinction ratio, between 10dB and 15dB, ensures effective signal differentiation. On the receiving end, it accommodates wavelengths from 1260nm to 1620nm, with a sensitivity of -32dBm and an overload threshold of -7dBm. This high-level optical design adheres to IEEE 802.3z and ANSI Fiber Channel standards, ensuring compatibility and reliable data transfer.
Electrically, the module features a differential impedance of 100Ω and supports input swing differentials ranging from 500mV to 2400mV. It includes features such as TX Disable, TX Fault, and Loss of Signal (LOS) detection, providing precise control and fault management. The robust electrical design enhances compatibility across a variety of networking setups.
Overall, the 1.25Gbps SFP Optical Transceiver is a high-performance and energy-efficient solution for ultra-long-distance networking applications. Its cutting-edge optical and electrical capabilities, combined with its compliance with industry standards, make it a trusted choice for advanced networking infrastructure.
The CT-SFP-EZX is a high-performance hot-pluggable SFP module designed for 1.25 Gb/s optical links up to 120 km on single-mode fiber. It combines a 1550 nm DFB laser transmitter with an APD photodiode receiver, ensuring extended optical budget and high sensitivity (–32 dBm). Operating from a single +3.3 V supply with <1 W power consumption, it supports LVPECL-compatible electrical interfaces, EEPROM diagnostics, and robust 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 suitable for both commercial and industrial environments.
