Product Detail：
HYTOPTODEVICE 800G OSFP Transceiver | 800GBASE 2 x FR4 Compatible Module (SMF, 1310nm, 2km, Dual Duplex LC, DOM, IHS/ Finned Top)
      The OSFP800-800G-2FR4-WDM1300-DLC is a high-performance H3C compatible 800G optical transceiver, engineered for next-generation 800G Ethernet, Data Center Interconnect (DCI), and InfiniBand Interconnects. It is a twin-port OSFP transceiver with a 2x400G 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 architecture of the H3C OSFP800-800G-2FR4-WDM1300-DLC? A1: It is an 800Gbps transceiver utilizing the OSFP form factor that features a twin-port (2x400G) architecture. Internally, it splits into two completely separate 400Gbps FR4 logical interfaces over a single physical module.

Q2: What do the "WDM1300" and "DLC" suffixes stand for? A2: "WDM1300" indicates that the optical module operates in the 1300nm wavelength band using Wavelength Division Multiplexing (CWDM4). "DLC" stands for Dual Duplex LC, it means that the module has two separate duplex LC ports on its front faceplate.

Q3: What is the maximum reach and optical wavelength specs for OSFP800-800G-2FR4-WDM1300-DLC?A3: Its transmission distance is  up to 2km over 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: How do you guarantee zero packet loss before shipment? A4: Every Juniper compatible  OSFP-2X400G-FR4-P  transceiver undergoes strict 100% full line-rate traffic looping and stress testing on Juniper QFX Series Data Center Switches. A live test report and validation video can be provided prior to dispatch.

Q5: Which modulation technology drives this H3C 800G OSFP transceiver? A5: The module implements high-speed 100G PAM4 (Pulse Amplitude Modulation 4-level) technology across 8 electrical and 8 optical channels (2x4x100G).
