Built for hosts recognizing OSFP-2X400G-LR4-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 10km, with Dual Duplex LC/UPC as the physical interface. The specifications and engineering guidance below support data-center designers evaluate optical reach, rack integration and host compatibility together, 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 10km 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.
Quality control covers the optical or electrical interface, host identification and operating link. The verified unit is then individually protected and cartoned. Customer references, rack groups and project packing lists can be added for volume orders.
For this model, the specified transmit-power range is -2.7~5.1dBm; the stated optical power budget is 6.3dB. 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.
Select the module by optical standard, reach and rack layout. Check the complete fiber channel, including panels and connectors, and keep dense bundles from blocking front-panel airflow. Account for listed power consumption and preserve enough space to remove a module without disturbing adjacent links. For this model, the principal parameters are data rate 850Gbps (8x 106.25Gbps), wavelength 1271nm, 1291nm, 1311nm and 1331nm, rated reach 10km.
Use OSFP-2X400G-LR4-P as the compatibility cross-reference and OSFP800-2LR4-A2 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.
Factory verification starts with the expected OSFP-2X400G-LR4-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.
No. It is an HT-manufactured compatible alternative for equipment that specifies OSFP-2X400G-LR4-P, not an original Juniper Networks-branded module.
Use Dual Duplex LC/UPC with SMF. The specified maximum reach is 10km, 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.
