Arista SFP-1G-LX-H Compatible 1000BASE-LX/LH SFP 1310nm 10km DOM Duplex LC/UPC SMF Optical Transceiver Module

The 1.25Gbps SFP Optical Transceiver (CT-SFP-LX) is an advanced networking module designed for mid-range optical communication over single-mode fiber (SMF) up to 20 kilometers. It features an SFP package with an LC connector and incorporates a 1310nm FP laser and PIN photo detector to ensure high-quality signal transmission. The transceiver supports a data rate of 1.25Gbps, making it ideal for Ethernet, telecom, and Fiber Channel applications. Its compatibility with LVPECL data input/output interfaces ensures seamless integration with host systems, while compliance with IEC-60825 laser safety standards and RoHS regulations guarantees safety and environmental sustainability.

The transceiver is engineered for reliability in various operating conditions, supporting supply voltages between 3.15V and 3.45V and operating temperatures from 0°C to +70°C for commercial use, and -40°C to +85°C for industrial applications. Its maximum power dissipation is capped at 1W, ensuring energy-efficient operation. With excellent protection against electromagnetic interference (EMI) and electrostatic discharge (ESD), the module is built for demanding network environments.

In terms of optical performance, the transmitter operates at a center wavelength of 1310nm, with an average output power ranging from -8dBm to -3dBm. The extinction ratio of 9dB to 15dB ensures effective signal clarity. The receiver section accommodates wavelengths between 1260nm and 1620nm, with a sensitivity of -24dBm and an overload threshold of -3dBm. The transceiver is compliant with IEEE 802.3z and ANSI Fiber Channel standards, ensuring compatibility and high signal integrity for various network protocols.

Electrically, the transceiver features a differential impedance of 100Ω and supports input swing differentials from 500mV to 2400mV. The receiver delivers an output swing range of 370mV to 2000mV. Control features such as TX Disable, TX Fault, and Loss of Signal (LOS) detection allow for precise operational management and fault monitoring.

Overall, the CT-SFP-LX transceiver is a high-performance, energy-efficient solution for mid-range networking applications. Its robust design and compliance with international standards make it a dependable choice for modern networking infrastructures.

The CT-SFP-LX is a reliable and cost-effective hot-pluggable SFP module designed for 1.25 Gb/s optical links over single-mode fiber up to 20 km. It integrates a 1310 nm FP laser transmitter with a PIN photodiode receiver, providing stable short-to-medium reach connectivity. Operating with a single +3.3 V power supply and <1 W power consumption, the module supports LVPECL-compatible differential I/O, 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, it is available in commercial and industrial temperature grades.
