QSFP-100G-4W40-I — QSFP28 100 Gbps

The QSFP-100G-4W40-I is a Cisco 100 Gbps QSFP28 module compliant with the 4WDM-40 MSA standard, enabling links up to 40 km over single-mode fiber (SMF) via a duplex LC (UPC) connector. Its industrial temperature range of -40 to 85 °C clearly distinguishes it from commercial-grade variants and guarantees operability in extreme conditions.

Leveraging the 4WDM-40 standard, this module uses four wavelengths over a single SMF fiber pair to deliver 100 Gbps at 40 km, making it ideal for inter-campus links or industrial metropolitan access. The -I version targets outdoor telecom environments or installations with high thermal variation. Genuine Cisco hardware, manufacturer warranty.
