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 20km using the complete channel rather than fiber distance alone.
Quality Assurance and Packaging
Each CWDM-SFP10G-1270-20 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 1~6dBm; receiver sensitivity is <-14.4dBm. 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. 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 20km.
Ordering Information
Quote HT part number CWDM-SFP10G-1270-20 together with OEM reference CWDM-SFP10G-1270-20 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.
H3C Compatibility and Factory Testing
The module is checked for host recognition as CWDM-SFP10G-1270-20, 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.
Frequently Asked Questions
Is this an original H3C transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies CWDM-SFP10G-1270-20, not an original H3C-branded module.
Which fiber and connector are required?
Use Duplex LC with SMF. The specified maximum reach is 20km, 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.
