Built for hosts recognizing OSFP-2X400G-FR4-P, this HT-manufactured Twin-port OSFP IHS/Closed Finned Top module delivers 800G transmission at 1271nm, 1291nm, 1311nm and 1331nm. Its rated reach is 2km, with Dual Duplex LC/UPC as the physical interface. The specifications and engineering guidance below support mixed-vendor networks document the correct compatibility identity at each host, while keeping HT manufacture separate from the OEM cross-reference.

Use this module for equipment interconnection over the specified single-mode fiber plant, including enterprise backbone, campus, metro or data-center interconnect links according to its rated distance. Confirm that both ends use the same optical standard and wavelength plan, and allow for connector, splice and patch-panel loss within the stated power budget.
Before deployment, check the host port type, supported data rate and firmware requirements. The 800G interface configuration must match the remote equipment; sharing a Twin-port OSFP IHS/Closed Finned Top housing alone does not make two transceiver types interoperable.
The single-mode link budget should include fiber attenuation, connectors, splices and panels over the intended 2km route. Keep the Dual Duplex LC/UPC interface clean and match the remote optical standard. Consider receiver overload as well as insufficient power on short links.
For this model, the specified transmit-power range is -3.2~4.4dBm; the stated optical power budget is 4dB. During commissioning, record the host diagnostic readings after the link has stabilized and compare them with those limits. DOM values are useful operational indicators, but they do not replace calibrated optical measurements when a link is marginal. Investigate unexpected loss through connector inspection, cleaning and a channel measurement before replacing the module. Diagnostic monitoring is listed as Supported. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.
A mixed-vendor optical link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether both ends use the same wavelength plan and optical standard. Related links locate equivalent hardware, but brand-specific identification must still be selected independently. For this model, the principal parameters are data rate 850Gbps (8x 106.25Gbps), wavelength 1271nm, 1291nm, 1311nm and 1331nm, rated reach 2km.
Factory verification starts with the expected OSFP-2X400G-FR4-P identity and finishes with an operating host link. EEPROM data, diagnostic visibility and the stated optical parameters are assessed together. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Use OSFP-2X400G-FR4-P as the compatibility cross-reference and OSFP-2FR4-800G as the HT ordering identity. Keep other reaches or wavelength directions on separate order lines. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. Customer references, rack groups and project packing lists can be added for volume orders.
No. It is an HT-manufactured compatible alternative for equipment that specifies OSFP-2X400G-FR4-P, not an original Juniper Networks-branded module.
Use Dual Duplex LC/UPC with SMF. The specified maximum reach is 2km, subject to fiber quality and total link loss.
Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
