Price list for SFP optical modules for data center interconnection

SFP coherent optical modules for DCI range from under $2,000 for short-reach 400G modules to over $130,000 for OEM 400G/800G ZR+ long-haul modules, with third-party options offering significant savings. Pricing OverviewShort-Reach 400G Modules (SR8): Typically used for in-rack or cross-row connections, priced between $1,400 and $1,800 from reputable third-party vendors, making them the most cost-effective entry point for 400G adoption.

Medium-

Reach Modules (DR4, FR4): Bridge data center rows or campus links. Third-party competition has driven prices down, though exact figures vary by vendor.

Long-

Reach Modules (LR4, ZR, ZR+): Used for DCI over longer distances.

OE

M LR4 modules can exceed $10,000, while coherent ZR+ modules for extended metro or regional interconnects may surpass $130,000. Third-party alternatives can reduce costs by 30–40% or more. 800G QSFP-DD Modules: Pricing is still stabilizing.

Buyers can expect 60–70% of OEM list prices for proven third-party 800G transceivers, with OEM modules preferred for critical workloads due to firmware and DOM compatibility.

Vendor Examples

Cisco 800G QSFP-DD and OSFP ZR/ZR+ Modules: Support 800G traffic over DWDM links up to 120 km for 800ZR and over 1000 km for 800G ZR+, suitable for single-span DCI or metro/regional interconnects.

GIGALIGH

T Coherent Modules: Offer 100G, 200G, and 400G pluggable digital coherent optical transceivers compatible with DCI BOX transport platforms, providing cost-effective solutions for long-haul and metro DCI applications. ConsiderationsOEM vs Third-Party: OEM modules are more expensive but may offer better compatibility and support. Third-party modules can provide substantial savings, especially for large-scale deployments.

Module Type Selection: The choice between SR, DR, LR, ZR, and ZR+ depends on distance, network topology, and required bandwidth. Coherent modules are essential for long-haul DCI links. Total Cost of Ownership (TCO): Beyond module price, consider cabling (DAC vs AOC), optical amplifiers, and network infrastructure when budgeting for DCI deployments.

In summary, SFP coherent optical module prices vary widely based on reach, speed, and vendor. Short-reach 400G modules are relatively affordable, while long-haul 400G/800G ZR+ modules represent the largest line-item expense in DCI networks. Third-party modules offer significant cost savings without compromising performance for many applications.
