Juniper OSFP-2X400G-FR4-P 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 OSFP-2X400G-FR4-P is a high-performance Juniper 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.

Primary Application Scenarios of 800G OSFP Optical Transceiver

The Juniper OSFP-2X400G-FR4-P is optimized for massive bandwidth scale-out scenarios, including:

• High-Density Spine-Leaf IP Fabrics: Doubles the uplink capacity from leaf/ToR switches to core spine switches by routing two separate 400G lines over a single physical 800G slot.

• AI/ML Infrastructure & Accelerated Computing: Connects ultra-dense GPU compute fabrics and low-latency storage arrays with robust line-rate bandwidth.

• Intra-Data Center Core Transport: Provides cost-effective, high-bandwidth 800G connections across distinct server halls and automated cloud environments up to 2km away.

• Carrier Edge & Cloud Service Providers: Maximizes slot and chassis efficiency in core routing matrices running intensive multi-tenant 5G, peering, and content distribution traffic.
  
  

Key Product Parameters of 800G 2FR4 Transceivers

Q1: What is the exact data rate and interface layout of the Juniper OSFP-2X400G-FR4-P?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 does the "-P" suffix represent in this Juniper module? A2: In Juniper's product architecture, the "-P" denotes Protected/Premium security firmware or platform authentication capabilities. It ensures the module passes Juniper's secure boot and hardware-integrity checks on specialized PTX and QFX platforms without generating secure-policy warnings.

Q3: What is the maximum reach and optical wavelength specs for OSFP-800G-2FR4?A3: It transmit traffic 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: Does this Juniper compatible module support Digital Optical Monitoring (DOM)?

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