Cisco QSFP-100G-SL4 Compatible 100G QSFP28 SL4 Transceiver Module

The QSFP-100G-SL4 compatible module is intended for Cisco platforms requiring a 100G QSFP28 transceiver. It specifies wavelength 850nm, reach 20m on OM3 / 30m on OM4 with MPO-12 through MMF.

OEM Part Number: QSFP-100G-SL4HT Part Number: QSFP-SL4-100G

Product Highlights

• Compatible alternative to Cisco QSFP-100G-SL4
• 100G connectivity at 103.125Gbps (4x 25.78Gbps)
• Optical wavelength: 850nm
• Specified reach: 20m on OM3 / 30m on OM4
• MPO-12 / MMF interface
• Digital diagnostic monitoring: Supported
• Operating temperature: 0 to 70°C (32 to 158°F)

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The MPO-12 interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.

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.

The module is programmed for equipment that recognizes the QSFP-100G-SL4 part number. Before shipment, we check EEPROM identification, link establishment and diagnostic readouts, then verify transmit and receiver performance against the stated optical specifications. Host hardware and software revisions can affect third-party module acceptance, so customers can provide the switch model and software release for a compatibility check before ordering.

Quote HT part number QSFP-SL4-100G together with OEM part number QSFP-100G-SL4 and the required quantity. Standard modules use our factory label; neutral labels, customer-branded packaging and project-specific compatibility coding are available on request. For mixed-brand installations, select the corresponding brand-specific page instead of assuming one EEPROM version fits every platform.

Each unit undergoes optical performance checks, compatibility verification and visual inspection before packing. Modules are supplied in protective blister trays or anti-static packaging and then cartoned for transport. Custom labels and project packing lists can be added for volume orders.

Standard products normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
