Fiber optic networking, straight from the factory
We manufacture fiber media converters, SFP modules and rack chassis — every unit link-tested before it ships. Private label and OEM programs welcome.

Trading Company vs. Source Factory
See the difference
Buying from a trading company and buying from the factory that actually builds your product are two different experiences.
Buying from a Trading Company
- ✕Markup on top of factory price — you pay for the middleman
- ✕No control over QC, batch consistency or quality
- ✕Slow technical answers; they don't design or build anything
- ✕Private label limited to stickers on someone else's product
Buying from OLIFI (Source Factory)
- ✓Factory-direct pricing with no middleman margin
- ✓Full QC: every unit tested before shipping
- ✓Engineers answer technical questions directly
- ✓True OEM/ODM: your brand, custom specs, your packaging
