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. This article compares typical cost ranges across speeds and transceiver types, explains why prices vary, and gives practical guidance for choosing the right optics for a given budget and performance requirement. The total came to $312,000 — 56% over budget before shipping, customs duties, spare inventory, and cabling were even included. However, advances in technology led to more compact form factors for 10 Gigabit Ethernet applications. Soon after 2001. Cisco QSFP-40G-SR4 Compatible 40GBASE-SR4 QSFP+ Optical Transceiver Module (MMF, 850nm, 150m, MTP/MPO, DDM) Cisco QSFP-40G-SR4 Compatible QSFP+ optical transceiver modules from QSFPTEK equipped with MTP/MPO-12 connectors that can transmit 150m through MMF OM4 fiber optic patch cords.
