The price of an 800G optical module can vary significantly depending on the optical technology, transmission distance, form factor, fiber type, vendor, and order volume. A short-reach 800G SR8 module may cost substantially less than a 2 km or 10 km single-mode solution.<\/p>\n

This guide explains the main factors that affect 800G optical module prices in 2026, compares different 800G variants, and looks at the total cost of deploying 800G compared with 400G and 100G solutions.<\/p>\n

 <\/p>\n

 <\/p>\n

What Is an 800G Optical Module?<\/strong><\/h2>\n

An 800G optical module<\/a> is a high-speed pluggable transceiver designed to provide up to 800 Gb\/s of aggregate data transmission. Depending on the module architecture, 800G solutions may use multiple 100G PAM4 lanes or higher-speed electrical\/optical lanes.<\/p>\n

Common 800G modules are available in form factors such as OSFP and QSFP-DD800<\/strong>, while specific products may use different electrical lane configurations and optical interfaces.<\/p>\n

Depending on the optical design, 800G transceivers can support short-reach multimode links as well as longer single-mode fiber connections ranging from several hundred meters to several kilometers.<\/p>\n

These modules are increasingly used in AI clusters, hyperscale data centers, high-performance computing, and high-bandwidth spine-leaf networks, where higher port speeds can reduce the number of switch ports and physical connections required.<\/p>\n

 <\/p>\n

 <\/p>\n

Why 800G Optical Module Prices Vary<\/strong><\/h2>\n

There is no single market price for an 800G optical module. The price difference between two 800G products can be substantial because of several factors.<\/p>\n

 <\/p>\n

Transmission Distance and Optical Technology<\/strong><\/h3>\n

Transmission distance is one of the most important cost factors.<\/p>\n

Short-reach solutions such as 800G SR8<\/strong>\u00a0are designed for multimode fiber and relatively short data-center links. They generally use simpler optical components than longer-reach single-mode solutions.<\/p>\n

By comparison, DR8, FR8, and LR8<\/strong>\u00a0solutions are designed for longer single-mode transmission and may require more sophisticated laser, wavelength, and optical components. As reach increases, optical complexity and manufacturing cost generally increase as well.<\/p>\n

 <\/p>\n

Fiber Type and Connector<\/strong><\/h3>\n

The fiber infrastructure also affects the overall cost.<\/p>\n

Short-reach 800G solutions commonly use multimode fiber and high-density MPO\/MTP-style connectors. Longer-reach solutions generally use single-mode fiber and may use MPO\/MTP or duplex LC interfaces depending on the optical architecture.<\/p>\n

Existing cabling should therefore be considered before selecting an 800G module. Choosing a module that matches the installed fiber and connector infrastructure can reduce the need for additional cabling.<\/p>\n

 <\/p>\n

Form Factor<\/b><\/strong><\/h3>\n

The form factor can also influence both module price and system-level cost.<\/p>\n

OSFP<\/strong><\/a> is widely used for high-density 800G networking and provides a relatively large thermal envelope. It is also positioned for future higher-speed networking applications.<\/p>\n

QSFP-DD800<\/strong><\/a>\u00a0provides high port density and maintains a compact QSFP-based form factor, making it attractive for applications where rack density and compatibility with existing equipment are important.<\/p>\n

The best choice depends on the switch platform, thermal design, port density, and network architecture rather than module price alone.<\/p>\n

 <\/p>\n

Vendor and Supply Chain<\/strong><\/h3>\n

Vendor positioning has a major impact on the final purchase price.<\/p>\n

The same 800G optical technology may be available through an original equipment manufacturer (OEM), an authorized distributor, or a third-party compatible supplier. Their pricing structures can differ considerably because they include different levels of validation, support, inventory, and warranty.<\/p>\n

For this reason, buyers should compare actual quotations rather than relying only on public list prices.<\/p>\n

 <\/p>\n

Order Volume and Lead Time<\/strong><\/h3>\n

Purchase volume is another important factor.<\/p>\n

A small enterprise order may receive a substantially different quotation from a data-center deployment involving hundreds or thousands of modules. Volume commitments, forecast agreements, and long-term supply contracts can often improve pricing and supply availability.<\/p>\n

Lead time can also affect the effective cost. During periods of constrained component supply, buyers may face higher prices or longer delivery times, particularly for specialized or longer-reach 800G products.<\/p>\n

800G Optical Module Price by Variant<\/strong><\/h2>\n

The following ranges should be treated as indicative market ranges rather than fixed prices. Actual quotations vary by vendor, compatibility coding, order quantity, warranty, region, and supply conditions.<\/p>\n

 <\/p>\n

In general, shorter-reach 800G modules are more cost-effective, while longer-reach solutions command a premium because of their more complex optical components.<\/p>\n

For AI data-center networks where the link distance is within the supported reach, DR8 can offer an attractive balance between transmission distance and cost.<\/p>\n

 <\/p>\n

OEM vs. Third-Party 800G Optical Modules<\/strong><\/h2>\n

One of the most important purchasing decisions is whether to use OEM-branded optics or qualified third-party compatible modules.<\/p>\n

OEM modules typically include platform validation, vendor support, warranty coverage, and compatibility assurance. These services contribute to a higher purchase price.<\/p>\n

Third-party compatible modules can reduce acquisition costs, particularly when the network platform is well established and the supplier provides appropriate coding, testing, and warranty support.<\/p>\n
