Specifications

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.

Wavelength-selective links require the exact channel plan at both ends. Confirm that filters pass 1270nm, then include their insertion loss in the 10km power budget. A nearby channel is not a substitute for the specified wavelength.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -1~5dBm; 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.

Mixed-Vendor Network Operation

A mixed-vendor optical link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether both ends use the same wavelength plan and optical standard. Related links locate equivalent hardware, but brand-specific identification must still be selected independently. For this model, the principal parameters are data rate 10Gbps, wavelength 1270nm, rated reach 10km.

Cisco Compatibility and Factory Testing

The module is checked for host recognition as CWDM-SFP10G-1270-10, 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 CWDM-SFP10G-1270-10 as the compatibility cross-reference and CWDM-SFP10G-10SP 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

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.
