◆ Introduction
1310nm optical modules, especially in single-mode (SMF) form, play a foundational role in many network types—offering a blend of cost-effectiveness, low chromatic dispersion, and adequate reach for medium-distance links. This wavelength is widely adopted in campus networks, metro area links, and data center interconnects because it avoids the high dispersion of longer wavelengths while delivering reliable performance.
1. Data Center Interconnects & Enterprise Networks
In data centers and large enterprise campuses, 1310nm LR modules are commonly used to connect buildings or floors within a 10 km radius. These modules are compatible with Ethernet (1G–100G), SONET/SDH, and Fibre Channel standards. Their ability to carry high-speed data across a few kilometers makes them ideal for aggregation and spine-leaf architectures.
2. Metropolitan (Metro) Networks
Metro networks benefit from 1310nm modules due to their lower dispersion and moderate attenuation over standard SMF—making them practical for city-wide links where amplification isn’t required. They serve as reliable building blocks for point-to-point connections and ring structures within urban environments.
3. Enterprise Access and LAN Links
For local area networks and enterprise access systems, 1310nm modules strike the right balance between performance and cost. They support uplinks between switches, routers, and servers at speeds from 1 Gbps to 25 Gbps using SFP, SFP+, and SFP28 optical modules. They’re especially valued in settings where budget and reliability matter.
4. 5G Transport and Backhaul Networks
In modern telecommunications, 1310nm Transceivers are often used for backhaul (or “bearer”) links in 5G networks, transporting high-bandwidth traffic between cell towers and aggregation points. These optical paths typically span a few kilometers—well within the effective range and performance profile of 1310nm LR modules.
5. Broadcast & Specialized Video Applications
Beyond traditional data networking, specialized formats such as SDI (serial digital interface) broadcasting leverage 1310 nm optical modules. For example, a SFP+ 10GBASE-LR operating at 1310nm can transmit high-definition video up to 20 km, enabling studio-to-transmission-center links with minimal fiber usage.
◆ Why 1310 nm Works—Key Advantages
Low Chromatic Dispersion: SMF shows minimal pulse spreading in the O-band (around 1310 nm), enhancing signal quality for mid-range distances.
Cost-Effective Componentry: Compared with 1550 nm optics, 1310 nm modules are typically less expensive to produce and sufficient for under-10 km links.
Wide Compatibility: They come in various pluggable form factors (SFP, SFP+, SFP28, QSFP28) suitable for multiple network architectures.
