Generic DWDM-SFP10G-40-I Compatible 10G SFP+ Transceiver Module

Generic DWDM-SFP10G-40-I Compatible 10G SFP+ Transceiver Module

Built for hosts recognizing DWDM-SFP10G-40-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 high-density deployments balance optical performance, port access and thermal planning, 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.

Quality Assurance and Packaging

Each DWDM-SFP10G-40-I 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.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -1~4dBm; the stated optical power budget is 14dB. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. 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.

High-Density Port and Thermal Planning

In a densely populated chassis, connector access and airflow form part of the optical-link design. Confirm that neighboring modules and patch leads leave room for latch operation, and include listed power consumption in the host thermal budget. Assess port density together with fiber management. For this model, the principal parameters are data rate 10 Gbps, wavelength 1560.61nm, rated reach 40km on OS2.

Ordering Information

Use DWDM-SFP10G-40-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.

Generic Compatibility and Factory Testing

Factory verification starts with the expected DWDM-SFP10G-40-I 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.

Frequently Asked Questions

Is this an original equipment manufacturer transceiver?

No. It is an HT-manufactured compatible transceiver supplied under our own manufacturer identity, not an original equipment manufacturer 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.

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.
