Optech 1.6T 2×FR4 Twin-Port OSFP Flat Top Transceiver

PAM4 | 1310nm | 2km SMF | Dual Duplex LC/UPC | DOM/DDM

As AI fabrics and cloud backbones move rapidly toward 1.6T switching, network operators need optics that combine higher port density, predictable reach, and production-grade manageability. The Optech 1.6T 2×FR4 Twin-Port OSFP Flat Top optical transceiver is designed for high-density 1.6T platforms requiring PAM4 performance over single-mode fiber (SMF) with DOM/DDM visibility and standards-based management.

With a maximum data rate of 1600Gbps and 2km reach, this module provides a practical, scalable path for next-generation data center and HPC interconnects—while keeping operational monitoring and compliance straightforward.

Key Features

  • 1.6T Max Throughput (1600Gbps) in a twin-port OSFP flat-top form factor

  • 2×FR4 optical architecture optimized for high-density front-panel deployments

  • 2km reach over SMF for data center and campus/metro edge interconnect scenarios

  • Dual duplex LC/UPC connectors for simple cabling and field operations

  • EML transmitter + PIN receiver for stable PAM4 link performance

  • DOM/DDM supported for real-time monitoring and alarms

  • Up to 30W max power consumption (thermal planning friendly for dense systems)

  • Commercial temperature range: 0 to 70°C demonstrate suitability for data center environments

  • Standards and management: OSFP MSA Rev 5.1, CMIS 5.2, IEEE 802.3dj (D1p2)

1.6T Twin-Port Architecture: Built for 200G-Lane PAM4 Systems

Modern 1.6T platforms increasingly standardize around 200G PAM4 electrical lanes to balance bandwidth and signal integrity. This module aligns with that architecture:

  • Electrical interface: 8×200G-PAM4

  • Optical interface: Dual 4×200G-PAM4 (two parallel 800G-class optical groups)

This mapping simplifies system design for 1.6T switching environments and supports clean scaling as networks grow from 800G to 1.6T port speeds.

Optical Performance and Reach (2km on SMF)

The transceiver uses FR4 LAN-WDM wavelengths (typical set shown below) to deliver reliable single-mode transmission:

  • Wavelengths: 1271nm, 1291nm, 1311nm, 1331nm

  • Max cable distance: 2km

  • Power budget: 4dB

  • TX optical power: -2.2 to -4.9 dBm

  • Minimum receiver power: -6.2 dBm

  • Receiver overload: 4.9 dBm

  • Extinction ratio: ≥ 3.5 dB

This performance profile supports 2km SMF links with clear engineering margins—ideal for dense interconnect blocks where predictable reach and quick deployment matter.

Standards, Management, and Operations (CMIS + DOM)

For large-scale deployments, operations teams need visibility and consistency. The Optech module includes:

  • CMIS 5.2 management model for coherent monitoring, inventory, and diagnostics

  • DOM/DDM support for key health metrics (temperature, voltage, optical TX/RX power, alarms)

  • Compliance alignment with OSFP MSA Rev 5.1 and IEEE 802.3dj (D1p2)

Typical Applications

  • AI/HPC fabrics scaling to 1.6T switching

  • Spine-leaf data center networks where high port density and SMF reach are required

  • High-speed interconnect blocks needing LC/UPC operational simplicity

  • Aggregation and campus/DC edge scenarios benefiting from 2km SMF capability
