DP01QS28-E20Cisco DP01QS28-E20 Compatible 100G QSFP28 Transceiver Module
Built for hosts recognizing DP01QS28-E20, this HT-manufactured QSFP28 module delivers 100G transmission at C-Band 5THz DWDM Tunable. Its rated reach is 80km (unamplified)300km (amplified), 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
This coherent interface is suited to data-center interconnect, metro transport and managed DWDM links where the host platform supports the stated modulation and FEC modes. Design the optical line around the actual launch power, receiver range, OSNR requirement and span loss; the stated reach is not a substitute for a link-budget calculation. Use matching coherent modules and the appropriate DWDM channel plan at both ends.
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.
Coherent deployment requires a line-system review, not merely a matching connector. Confirm the DWDM channel, launch-power range, receiver limits, OSNR and FEC mode at both ends. Span loss and amplifier operation must remain inside the supported envelope, and stated reach should be validated against the actual route.
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.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -8~-4dBm; the stated optical power budget is 22dBm. A sound acceptance record includes link state, diagnostic temperature, supply voltage and transmit or receive levels where the host exposes them. Compare the readings with the stated ranges rather than treating any received light as proof of adequate margin. Persistent alarms or borderline values should trigger an end-face and complete-channel inspection. 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 100Gbps, wavelength C-Band 5THz DWDM Tunable, rated reach 80km (unamplified)300km (amplified).
Ordering Information
Quote HT part number QSFP-ZR-100G-S together with OEM reference DP01QS28-E20 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.
Cisco Compatibility and Factory Testing
The module is checked for host recognition as DP01QS28-E20, 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 Cisco transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies DP01QS28-E20, not an original Cisco-branded module.
Which fiber and connector are required?
Use Duplex LC/UPC with Duplex SMF. The specified maximum reach is 80km (unamplified)300km (amplified), 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.
