Specifications

Applications and Optical Link Design

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The MTP/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 multimode channel should use the fiber grade associated with the stated 200m on OM3 / 300m on OM4 reach. Keep the MTP/MPO-12 end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -4~4dBm. 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.

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 103.125Gbps (4x 25.78Gbps), wavelength 850nm, rated reach 200m on OM3 / 300m on OM4.

Extreme Compatibility and Factory Testing

The module is checked for host recognition as 100G-ESR4-QSFP300M, 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 100G-ESR4-QSFP300M as the compatibility cross-reference and QSFP-ESR4-100G 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.

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.
