SFP module 1.25g Optical Transceiver

Enhance your network’s backbone with our professional-grade 1.25G SFP optical module, a versatile and high-performance transceiver solution engineered for reliable, long-distance data transmission. This SFP module 1.25g hot-pluggable SFP module delivers bi-directional data rates up to 1.25Gb/s, making it fully compatible with Gigabit Ethernet (IEEE 802.3z) and 1x/2x Fiber Channel (FC-PI) standards for maximum application flexibility. Its key selling point is an exceptional long-haul capability, utilizing 1310nm or 1550nm wavelengths over single-mode fiber (SMF) to achieve stable connections from 10 km to an industry-leading extended reach of up to 100 km, ideal for connecting switches or data center interconnects. Built with a metal enclosure for superior EMI protection and featuring very low jitter and power dissipation (<700mW), it ensures signal integrity and operational stability.

SFP module 1.25g Features:

Up to 1.25Gb/s Bi-directional Data Links: Ensures fast, reliable data transfer across fiber optic networks.

Long-Range Connectivity: Supports distances up to 100 km (62.1 miles) over single-mode fiber (SMF), making it ideal for long-haul network applications.

Hot-Pluggable SFP Footprint: Easily installable and replaceable without needing to power down the system.

1310/1550nm FP/DFB Laser Technology: Offers excellent optical performance for both short and long-distance applications.

Duplex LC Connector: Standard LC connector for ease of installation and compatibility with existing systems.

Low Jitter Performance: Ensures a stable signal and minimizes data loss or interference.

Low Power Consumption: Typical power dissipation of less than 700mW, contributing to energy efficiency.

Metal Enclosure: Provides EMI shielding for enhanced signal integrity and reduced interference.

Application:

• Switch to switch interface
• High speed I/O for file servers .
• Bus extension applications
