Frequently Asked Questions
What is a QSFP+ 40GBASE-SWDM4 transceiver used for?
A QSFP+ 40GBASE-SWDM4 transceiver is used to enable 40 Gigabit Ethernet connectivity in data center networks, enterprise switches, and high-performance computing systems. It converts electrical signals to optical signals for transmission over multimode fiber cabling, supporting distances up to 100 meters with four-wavelength multiplexing technology.
Is the ENET QSFP-40G-SWDM4-S-ENC compatible with Cisco equipment?
Yes, the ENET QSFP+ module is fully Cisco-compatible and coded for seamless operation with Cisco Nexus switches, UCS systems, and other Cisco networking infrastructure. It meets Cisco's compatibility standards and can be deployed as a direct replacement in existing Cisco environments.
What does DOM (Digital Optical Monitoring) do on this transceiver?
DOM enables real-time monitoring of critical optical parameters including transmitted and received optical power levels, module temperature, and transceiver health status. This allows network administrators to proactively identify signal degradation, prevent link failures, and optimize network performance through continuous diagnostics.
Can this QSFP+ transceiver work with OM3 and OM4 multimode fiber?
Yes, the 850nm QSFP+ module is designed for use with both OM3 and OM4 multimode fiber cabling. OM4 fiber supports the full 100-meter range at 40Gb speeds, while OM3 fiber typically supports up to 70 meters at this data rate, depending on cable quality and environmental conditions.
