10G Optical Module Single-Mode Specifications

A 10G single-mode optical module is an SFP+ transceiver that delivers 10 Gigabit Ethernet over single-mode fiber up to 10 km using a 1310 nm wavelength and LC duplex connectors.

Overview

A 10G single-mode optical module (SFP+) is a compact, hot-pluggable transceiver designed to convert electrical signals from switches or routers into optical signals suitable for single-mode fiber (SMF) transmission. These modules are widely used in data centers, enterprise networks, and telecom environments to provide reliable long-distance links with minimal signal loss and low latency.

Key Specifications

Data Rate: 10 Gigabit per second (10G) for high-speed network connectivity. Wavelength: 1310 nm, optimized for long-distance single-mode fiber transmission. Maximum Distance: Up to 10 kilometers over single-mode fiber.

Connector Type: LC duplex, compatible with standard single-mode patch cords. Standards Compliance: Conforms to 10GBASE-LR (Long Reach) under IEEE 802. 3ae, ensuring interoperability across vendors.

Form Factor: SFP+ small form-factor, allowing high port density and hot-pluggable operation. Optional Features: Digital Optical Monitoring (DOM/DDM) for real-time measurement of optical power, temperature, and voltage. AdvantagesLong-Distance Connectivity: Supports up to 10 km, ideal for connecting switches across buildings or campus networks.

Low Latency and High Stability: Efficient signal processing ensures minimal delay and reliable connections for high-performance applications like cloud computing, video streaming, and real-time data processing. Energy Efficient: Designed for low power consumption while maintaining high-speed performance. Interoperability: Multi-source agreement (MSA) compliance allows use with a wide range of switches, routers, and network interface cards.

Deployment Considerations

Ensure the fiber type is single-mode (SMF) with a core diameter of approximately 9 µm to minimize modal dispersion. Verify optical budget and link loss to maintain signal integrity over the intended distance. Use compatible LC duplex patch cords and maintain proper handling to avoid damage to the fiber or module.

Avoid looking directly into the fiber ends or powered transceivers, as they are Class 1 laser products. In summary, a 10G single-mode SFP+ module is a reliable, high-performance solution for long-distance 10 Gigabit Ethernet connections, offering low latency, high stability, and broad compatibility for modern networking infrastructures.
