As next-generation data centers, AI computing, and hyperscale interconnects demand ever-growing bandwidth and lower latency, the OSFP transceivers form factor have become a leading solution for 400G, 800G, and emerging 1.6T Ethernet deployments.
Optech Technology, a Taiwan-based and TAA-compliant manufacturer, delivers a wide portfolio of OSFP transceivers designed for ultra-reliable performance across enterprise, telecom, and AI infrastructures.
1. 400G OSFP Transceivers
OSFP was originally introduced to meet the thermal and density challenges of 400G high-performance optics. The following 400G modules are widely deployed:
400G OSFP-SR4

- Transmission distance: up to 100 meters (OM4)
- Application: TOR switch-to-switch in hyperscale DCs
400G OSFP-DR4
- Single-mode 500m reach with 4x100G PAM4 lanes
- MPO-12 connector
- Ideal for spine-to-leaf architecture
- Compatible with breakout to 100G DR modules
400G OSFP-DR4+
- Improved version with extended reach to 2km
- Works well in AI/ML clusters using NVIDIA Quantum switches
- Fully compliant with OSFP MSA and IEEE 802.3bs
2. 800G OSFP Transceivers

800G OSFP-2xDR4
- Dual 400G DR4 architecture
- 8x100G PAM4 over SMF
- Up to 500m reach
- Common in NVIDIA-based distributed GPU training topologies
800G OSFP-2xDR4+
- Extended 2km reach
- Uses 100G PAM4 lanes over SMF
- Compatible with NVIDIA SN5600, SN4700
800G OSFP-2xER4
- Long-haul version with 40km reach
- CWDM4 optics, dual LC duplex connector
- Used in metro DCI and hyperscale interconnects
3. 1.6T OSFP Transceivers – Ready for the Next Leap
Optech Technology is actively developing 1.6Tbps OSFP DR8 modules featuring:
- 8x200G PAM4 electrical/optical lanes
- 2km transmission
- Single-mode fiber (MPO-16)
- Targeting next-gen AI fabric and rack-to-rack massive data transport
