What does the 1310 optical module represent

1310 nm optical modules are widely available in SFP+, SFP28, and QSFP28 form factors, supporting data rates from 1G to 100G over single-mode fiber for medium-distance links.

Overview

1310 nm optical modules operate in the O-band (1260–1360 nm), offering low dispersion, stable performance, and cost efficiency, making them ideal for data centers, enterprise backbones, campus networks, and metro access networks . They are typically used with single-mode fiber (SMF) to achieve longer transmission distances with minimal signal loss and distortion .

Common Types and Data Rates

• SFP+ 10G Modules: Support 10 Gbps data rates, often with a reach of up to 10 km over SMF. Example: XG-SFP-LR-SM1310, compliant with IEEE 10GBASE-LR standards .
• SFP28 25G Modules: Designed for high-speed campus and data center links, supporting 25 Gbps over medium distances .
• QSFP28 100G Modules: Suitable for large-scale data center interconnects, providing 100 Gbps over single-mode fiber .
• 1G Modules: Available for legacy or lower-speed networks, typically supporting distances up to 10 km.

Key Features

• Form Factors: SFP+, SFP28, QSFP28, compatible with switches, routers, and servers from vendors like Cisco, Juniper, Arista, and Huawei .
• Transmission Distance: Medium-range links, generally 10 km for standard modules; industrial-grade modules may support extended distances and wider temperature ranges (-40°C to 85°C), .
• Industrial-Grade Options: Designed for harsh environments with high EMI resistance and robust construction .
• Standards Compliance: IEEE 802.3ae, SFF-8431, SFP+ MSA, RoHS, ensuring interoperability and reliability .
• Applications: Campus networks, data center interconnects, metropolitan area networks, and enterprise backbones .

Considerations When Choosing a Module

• Compatibility: Ensure the module matches your existing network equipment.
• Data Rate and Reach: Select based on required speed and distance.
• Environmental Requirements: For outdoor or industrial deployments, choose modules with extended temperature and EMI tolerance.
• Optical Performance: Check insertion loss, receiver sensitivity, and optical power margin for reliable operation . 1310 nm optical modules provide a flexible and reliable solution for medium-distance fiber optic communication, supporting a wide range of network speeds and applications while maintaining stable performance and cost efficiency.
