1.6T OSFP224 Overview

The 1.6T OSFP224 category contains two 1.6T optical transceiver modules for high-speed interconnects in supercomputing and high-performance computing environments. Both models use the OSFP224 form factor with a finned-top thermal design, PAM4 modulation, 1310nm optics, and DOM support. The series comprises two single-mode modules covering transmission distances from 500m to 2km. Depending on the optical architecture, the transceivers use either dual MTP/MPO-12 APC connectors for parallel optical links or dual duplex LC connectors for wavelength-division multiplexed links. They integrate into computing and storage infrastructure for high-performance interconnection.

OSFP-1.6T-2DR4 This 1.6T OSFP224 transceiver supports 2xDR4/DR8 parallel optical transmission at 1310nm over single-mode fiber. Its dual MTP/MPO-12 APC connectors divide the optical interface into two DR4 paths, together forming the DR8 link architecture. The module supports transmission distances up to 500m and incorporates PAM4 modulation, DOM monitoring, and a finned-top housing. It is designed for high-speed optical connections within supercomputing, HPC, computing, and storage infrastructure.

OSFP-1.6T-2FR4 This 1.6T OSFP224 transceiver supports 2xFR4/FR8 wavelength-division multiplexed transmission at 1310nm over single-mode fiber. It uses two duplex LC connectors, with each connector carrying one FR4 optical path to form the combined FR8 link. The module reaches distances up to 2km and features PAM4 modulation, DOM monitoring, and a finned-top housing. It supports longer-reach interconnections across supercomputing, HPC, computing, and storage systems.

FAQ

What are the main optical architecture, connector, and reach differences between OSFP-1.6T-2DR4 and OSFP-1.6T-2FR4?

OSFP-1.6T-2DR4 uses parallel single-mode optics with dual MTP/MPO-12 APC connectors and supports up to 500m. OSFP-1.6T-2FR4 uses wavelength-division multiplexed single-mode optics with dual duplex LC connectors and supports up to 2km.

How does OSFP-1.6T-2DR4 divide its 1.6T optical interface across the two MTP/MPO-12 APC connectors?

It provides two DR4 optical paths, with each MTP/MPO-12 APC connector carrying one path. The two parallel four-channel paths together form the module’s DR8 optical architecture for 1.6T transmission.

What is the maximum single-mode fiber distance supported by the OSFP-1.6T-2DR4 optical transceiver?

Up to 500m. The OSFP-1.6T-2DR4 uses 1310nm parallel optical transmission over single-mode fiber and presents its optical channels through two MTP/MPO-12 APC connectors.

How are the two duplex LC connectors used by the OSFP-1.6T-2FR4 optical transceiver?

Each duplex LC connector carries one FR4 optical path. The two wavelength-division multiplexed FR4 paths operate together as the module’s combined FR8 architecture for 1.6T single-mode transmission.

How far can the OSFP-1.6T-2FR4 transmit over single-mode fiber in a supported optical link?

Up to 2km. The OSFP-1.6T-2FR4 uses 1310nm wavelength-division multiplexed optics and dual duplex LC connectors for longer-reach links between supported computing, storage, and high-performance interconnect systems.

Can OSFP-1.6T-2DR4 and OSFP-1.6T-2FR4 use the same fiber cabling and connector configuration?

No. Both models operate over single-mode fiber, but OSFP-1.6T-2DR4 requires dual MTP/MPO-12 APC parallel-fiber connections, while OSFP-1.6T-2FR4 requires two duplex LC connections for its multiplexed optical paths.

Which core optical, mechanical, and monitoring features are shared by both models in the 1.6T OSFP224 category?

Both models use the OSFP224 form factor with a finned-top thermal design, PAM4 modulation, 1310nm single-mode optics, and DOM support. They are designed for 1.6T high-speed interconnections in supercomputing, HPC, computing, and storage infrastructure.
