Cisco OSFP-2X400G-FR4 Compatible 800G OSFP 2xFR4 Optical Transceiver Module | HYTOPTODEVICE

Product Detail：
HYTOPTODEVICE 800G OSFP Transceiver | 800GBASE 2 x FR4 Compatible Module (SMF, 1310nm, 2km, Dual Duplex LC, DOM, IHS/ Finned Top)
      The HYTOPTODEVICE OSFP-2X400G-FR4 is a high-performance Cisco compatible 800G optical transceiver, engineered for next-generation 800G Ethernet, Data Center Interconnect (DCI), and InfiniBand Interconnects. It is a twin-port 2x400G OSFP module with a 2xFR4 architecture, allowing for high-density 800G links or 2x400G breakouts over Single-Mode Fiber (SMF) via dual Duplex LC connectors. Fully compliant with OSFP MSA and IEEE 802.3ck protocols, it is powered by top-tier core chipsets and CWDM 1310nm laser technology to deliver 800Gbps (8x100G PAM4) aggregate throughput up to 2km.

     Designed for air-cooled Ethernet switches, this twin-port OSFP IHS ( Finned Top) transceiver offers low latency, low power, and high reliability. It seamlessly supports spine-leaf uplinks, ToR switch downlinks to network adapters, and direct connections to BlueField-3 DPUs. It is the ideal interconnect solution for AI, HPC, and cloud data centers.

Key Product Parameters of 800G 2FR4 Transceivers

Q1: What is the exact data rate and interface layout of the Cisco OSFP-2X400G-FR4?A1:It is an 800Gbps transceiver in an OSFP form factor employing a dual-port (2x400G) architecture. It provides two completely independent 400Gbps FR4 logical interfaces on a single physical module.

Q2: What type of fiber connector and cabling does this module use?A2: It features a dual duplex LC optical interface (two standard LC connections on the front faceplate). It uses standard single-mode fiber (SMF) duplex LC-to-LC patch cords, eliminating the need for expensive MPO breakout cables.

Q3: What is the maximum reach and optical wavelength specs?A3: It transmit traffic up to 2 kilometers (2km) over standard single-mode fiber(SMF) via dual duplex LC.It has 2x400G port, Each 400G port utilizes 4 CWDM wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm.

Q4: Which modulation technology does the OSFP-2X400G-FR4 use?A4: The transceiver implements high-speed 100G PAM4 (Pulse Amplitude Modulation 4-level) technology across 8 electrical and 8 optical channels (2x4x100G).

Q5: Does this Cisco compatible module support Digital Optical Monitoring (DOM)?

A5: Yes. It supports real-time DDM. you can independently monitor telemetry data—such as Tx/Rx optical power, bias current, temperature, and voltage.
