The QSFP-CWDM4-100G-I compatible module serves equipment requiring a 100G QSFP28 interface with 1310nm optics and a 2km rating. Connection is through Duplex LC. Product data, application guidance and factory verification are presented together to support installers plan a serviceable optical connection at the equipment rack.

Plan the fiber route before removing connector protection. The patch lead should follow its manager without pulling on the transceiver, while leaving space to release the latch and service adjacent ports. Protect the end face until final connection and avoid tight bends immediately behind warm exhaust air. For this model, the principal parameters are data rate 103.1Gbps, wavelength 1310nm, rated reach 2km.
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.
The industrial temperature rating makes this version appropriate for controlled outdoor cabinets, transport nodes and other installations exposed to wider ambient temperature variation. Adequate airflow, protected cable routing and host-platform temperature limits still apply.
Wavelength-selective links require the exact channel plan at both ends. Confirm that filters pass 1310nm, then include their insertion loss in the 2km power budget. A nearby channel is not a substitute for the specified wavelength.
For this model, the specified transmit-power range is -2.5~6.5dBm; the stated optical power budget is 9dB. 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.
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.
Factory verification starts with the expected QSFP-CWDM4-100G-I 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.
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-CWDM4-100G-I, not an original Brocade-branded module.
Use Duplex LC with SMF. The specified maximum reach is 2km, 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.
Quote HT part number QSFP-CWDM4-100G-I together with OEM reference QSFP-CWDM4-100G-I 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.
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.
