Generic CWDM-SFP10G-40S Compatible 10G SFP+ Transceiver Module

Generic CWDM-SFP10G-40S Compatible 10G SFP+ Transceiver Module

Built for hosts recognizing CWDM-SFP10G-40S, this HT-manufactured SFP+ module delivers 10G transmission at 1270nm. Its rated reach is 40km, with Duplex LC 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.

Before deployment, check the host port type, supported data rate and firmware requirements. The 10G interface configuration must match the remote equipment; sharing a SFP+ housing alone does not make two transceiver types interoperable.

For this 1270nm interface, verify channel spacing and filter compatibility. Passive filters add loss even without active equipment, so assess 40km using the complete channel rather than fiber distance alone.

Quality Assurance and Packaging

Each CWDM-SFP10G-40S 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 0~5dB; receiver sensitivity is <-15dBm. 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. 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 10Gbps, wavelength 1270nm, rated reach 40km.

Ordering Information

Quote HT part number CWDM-SFP10G-40S together with OEM reference CWDM-SFP10G-40S and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.

Generic Compatibility and Factory Testing

Compatibility testing for CWDM-SFP10G-40S 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.

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 with SMF. The specified maximum reach is 40km, 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.
