Fujitsu FIM81550 Compatible XFP X2 10GBASE-ZR Transceiver Module
Built for hosts recognizing FIM81550, this HT-manufactured X2 module delivers XFP transmission at 1550nm. Its rated reach is 80km, with SC duplex as the physical interface. The specifications and engineering guidance below support procurement teams match an equipment parts list to a clearly defined optical product, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design
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 XFP interface configuration must match the remote equipment; sharing a X2 housing alone does not make two transceiver types interoperable.
For this 1550nm interface, verify channel spacing and filter compatibility. Passive filters add loss even without active equipment, so assess 80km using the complete channel rather than fiber distance alone.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is 0~4dBm; receiver sensitivity is < -24 dBm. A sound acceptance record includes link state, diagnostic temperature, supply voltage and transmit or receive levels where the host exposes them. Compare the readings with the stated ranges rather than treating any received light as proof of adequate margin. Persistent alarms or borderline values should trigger an end-face and complete-channel inspection. 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.
Procurement and Asset Identification
A useful purchase order identifies the host platform, expected OEM code and optical standard separately. This prevents a module with the same housing but another wavelength, reach or identification profile from being substituted. For mixed deployments, keep one order line per OEM reference and reconcile each received unit with its intended port. For this model, the principal parameters are data rate 10Gbps, wavelength 1550nm, rated reach 80km.
Fujitsu Compatibility and Factory Testing
The module is checked for host recognition as FIM81550, link establishment and diagnostic reporting. Physical cage fit alone is not treated as evidence of compatibility. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Ordering Information
Use FIM81550 as the compatibility cross-reference and FIM81550 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.
Quality Assurance and Packaging
Each FIM81550 compatible module is inspected, powered up and functionally checked before protective packing. Dust caps and individual trays shield the interface during transport. Customer references, rack groups and project packing lists can be added for volume orders.
Frequently Asked Questions
Is this an original Fujitsu transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies FIM81550, not an original Fujitsu-branded module.
Which fiber and connector are required?
Use SC duplex with SMF. The specified maximum reach is 80km, subject to fiber quality and total link loss.
Can it be mixed with another wavelength or reach version?
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.
Shipping and Lead Time
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.
