The modules met the same QSFP28 LR4 optical specification, supported the same 10km single-mode fiber reach, and were coded for the same switch platform. The same 400 modules would have cost $112,000. The total came to $312,000 — 56% over budget before shipping, customs duties, spare inventory, and cabling were even included. The SEP 100G QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to. Let's take a look at different factors that could affect 100G QSFP28 optical module cost. Generally, the two main milestones in this phase are. The price of a 10G SFP+ module typically ranges from low double digits to several hundred dollars, and in some cases even higher. This wide gap is not random—it is mainly driven by transmission distance, brand strategy, compatibility requirements, and optical technology. First, a significant share of the total cost comes from raw materials, such as lasers, silicon chips, and specialty semiconductors.
