FT-OSFP-XD-1.6T-4FR2 1.6T OSFP-XD 4xFR2 PAM4 1291/1311nm 2km SN SMF Optical Transceiver Module
Engineered for the extreme bandwidth and topology flexibility demanded by next-generation hyperscale data centers, the FT-OSFP-XD-1.6T-4FR2 module delivers an aggregate data rate of 1.6Tbps utilizing advanced 200G PAM4 modulation across four independent 400G-FR2 channels. Operating at 1291/1311nm wavelengths, it ensures reliable, low-latency transmission up to 2km over Single Mode Fiber (SMF), perfectly suited for intra-campus and row-to-row interconnects.
Leveraging the OSFP-XD (eXtended Density) form factor, this module provides superior thermal headroom and front-panel density compared to standard OSFP, supporting the high-power requirements of 1.6T DSPs. The SN connector interface consolidates four duplex pairs into a compact footprint, enabling native 4x 400G breakout capabilities from a single port—ideal for connecting high-density leaf-spine architectures, NVIDIA Spectrum-X/Quantum-X800 platforms, and heterogeneous AI compute clusters without rewiring existing duplex SMF plants.
Key Features
Quad-Breakout Architecture: 1.6T aggregate bandwidth configured as 4x 400G-FR2 (4x 2x 200G PAM4 lanes) via a single SN connector.
Extended Reach: 2km transmission over SMF at 1291nm/1311nm (CWDM/FR2 grid), doubling typical DR reach for campus-scale DCI.
Next-Gen Form Factor: OSFP-XD MSA compliant, offering enhanced thermal capacity (>30W) and double the faceplate density of QSFP-DD.
Flexible Topology: Supports 1x1.6T, 2x800G, 4x400G, and 8x200G configurations for versatile fabric designs.
Advanced Modulation: 200G/lane PAM4 electrical and optical signaling for maximum spectral efficiency.
Standards Compliance: Compliant with OSFP-XD MSA, IEEE 802.3dj(draft), CMIS Rev 5.x, and RoHS.
Target Applications
1.AI/ML Backend Networks: Scaling GPU clusters requiring 1.6T uplinks broken out to multiple 400G NICs or switches.
2.Hyperscale Data Centers: High-density spine-leaf topologies leveraging duplex SMF infrastructure.
3.Campus Interconnects (DCI): 2km reach for inter-row or inter-building connectivity within enterprise campuses.
4.Cloud Networking: Flexible breakout-rich layers serving mixed-speed compute and storage nodes.
