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 100G interface configuration must match the remote equipment; sharing a QSFP28 housing alone does not make two transceiver types interoperable.

Before commissioning, measure the complete single-mode channel against the stated budget for 500m. Inspect every Duplex LC/UPC connection and record diagnostic power where supported. Both ends must agree on rate, wavelength and optical standard.

Intel Compatibility and Factory Testing

Factory verification starts with the expected SPTSLP2SLCDF 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.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -2.9~4dBm; the stated optical power budget is 3dB. 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.

Interoperability and Host Configuration

Check three layers before deployment: host acceptance of the module identity, port support for the stated rate, and a matching optical standard at the remote interface. For breakout operation, confirm lane configuration too. Similar-looking cages can behave differently across speeds and firmware settings. For this model, the principal parameters are data rate 103.125Gbps (4x 25.78Gbps), wavelength 1310nm, rated reach 500m.

Ordering Information

Quote HT part number QSFP-DR-100G together with OEM reference SPTSLP2SLCDF 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.

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

Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. Customer references, rack groups and project packing lists can be added for volume orders.

Frequently Asked Questions

Is this an original Intel transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies SPTSLP2SLCDF, not an original Intel-branded module.

Which fiber and connector are required?

Use Duplex LC/UPC with SMF. The specified maximum reach is 500m, 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.
