Built for hosts recognizing QSFP-SR1.2-100G, this HT-manufactured QSFP28 module delivers 100G transmission at 850/910nm. Its rated reach is 70m on OM3 / 100m on OM4 / 150m on OM5, with Duplex LC as the physical interface. The specifications and engineering guidance below support network teams verify host acceptance as well as physical interface fit, while keeping HT manufacture separate from the OEM cross-reference.

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.
For this coherent interface, document the wavelength plan and modulation or FEC settings before commissioning. Measure span loss and verify adequate OSNR. Interoperability depends on compatible coherent modes as well as form factor, so another coherent part number must not be substituted without engineering review.
Compatibility testing for QSFP-SR1.2-100G 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.
For this model, the specified transmit-power range is -6.2dBm~4dBm; the stated optical power budget is 2dB. 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. 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.
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 106.25 Gbps, wavelength 850/910nm, rated reach 70m on OM3 / 100m on OM4 / 150m on OM5.
Use QSFP-SR1.2-100G as the compatibility cross-reference and QSFP-SR1.2-100G 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.
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 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.
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-SR1.2-100G, not an original Dell-branded module.
Use Duplex LC with MMF. The specified maximum reach is 70m on OM3 / 100m on OM4 / 150m on OM5, subject to fiber quality and total link loss.
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.
