Topnet System's 1.6T portfolio covers both OSFP (8x200G electrical) and OSFP-XD (16x100G electrical) form factors, built on 200G-per-lane PAM4 optics for XDR-class AI fabrics and 102.4T switching platforms. The family spans DR8 and DR8D parallel single-mode options (500m and 2km, MPO-16 or dual MPO-12 APC), 2xFR4 duplex-LC designs that run as two independent 800G-FR4 links, and 4xFR2 SN-connector variants for high-density breakout - so the fiber plant you installed for 800G carries forward without rework.

Every module ships with full test data. Engineering samples are available to qualified programs under our 30-day testing policy; see the form factor decoder for how OSFP224 and OSFP-XD fit the pluggable roadmap, or step down to the shipping 800G family.
