The cost of an optical engine for data center applications can vary widely based on the specifications such as bandwidth, form factor, and manufacturer. Here’s a general range for the price of optical transceivers (which include optical engines as part of the component):
-
100G Optical Engines: Typically priced around $200 to $600 per unit.
-
200G Optical Engines: Around $1,000 to $2,000 per unit.
-
400G Optical Engines: Prices can range from $3,000 to $6,000 or more per unit.
Factors Affecting Cost:
-
Bandwidth: Higher bandwidth (e.g., 400G and beyond) will command a higher price.
-
Volume Purchases: Data center operators purchasing in large quantities typically get discounts.
-
Technology and Integration: Advanced photonic integration (such as POET Technologies' solutions) can potentially reduce costs by combining components into a single chip.
For an accurate and specific price, it would be necessary to contact manufacturers or vendors directly, as prices can fluctuate based on demand, supply chain factors, and custom requirements.
