Brocade 10G-SFPP-ZRD-1560.61-I Compatible 10G SFP+ Transceiver Module 40km on OS2

Built for hosts recognizing 10G-SFPP-ZRD-1560.61-I, this HT-manufactured SFP+ module delivers 10G transmission at 1560.61nm. Its rated reach is 40km on OS2, with Duplex LC/UPC as the physical interface. The specifications and engineering guidance below support structured fiber installations preserve a documented and serviceable optical channel, 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.
The industrial temperature rating makes this version appropriate for controlled outdoor cabinets, transport nodes and other installations exposed to wider ambient temperature variation. Adequate airflow, protected cable routing and host-platform temperature limits still apply.
For this 1560.61nm interface, verify channel spacing and filter compatibility. Passive filters add loss even without active equipment, so assess 40km on OS2 using the complete channel rather than fiber distance alone.
Brocade Compatibility and Factory Testing
Compatibility testing for 10G-SFPP-ZRD-1560.61-I combines identification with a live link and available transmit, receive and alarm information. Connector condition is inspected separately. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -1~4dBm; the stated optical power budget is 14dB. 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. 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.
Structured Fiber Pathways and Serviceability
Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate 10Gbps, wavelength 1560.61nm, rated reach 40km on OS2.
Ordering Information
Use 10G-SFPP-ZRD-1560.61-I as the compatibility cross-reference and DW-SFP10G40-21-I 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.
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.
Quality Assurance and Packaging
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.
Frequently Asked Questions
Is this an original Brocade transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies 10G-SFPP-ZRD-1560.61-I, not an original Brocade-branded module.
Which fiber and connector are required?
Use Duplex LC/UPC with SMF. The specified maximum reach is 40km on OS2, 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.
