As a 1G short-reach module over multimode fiber, it is the classic access-layer optic for in-building uplinks, IDF-to-MDF runs, and edge-switch aggregation where copper distance falls short. It remains a staple in campus and enterprise networks still running gigabit to the closet over installed multimode. It operates 550m.

Each unit is programmed to match Juniper host values and bench-tested for traffic conformity, DOM-threshold accuracy, and optical cleanliness before it leaves the bench. Compliance documentation (RoHS declaration, IEC 60825-1 laser classification) is available on request for project quotes.
