CVR-QSFP-SFP10G-BCC | Cisco Compatible QSFP to SFP+ Adapter Module (40G to 10G Conversion)

Q: Will this work in place of the Cisco CVR-QSFP-SFP10G?
A: Yes. The CVR-QSFP-SFP10G-BCC conforms to the same SFF-8431 and SFF-8436 MSA standards as the Cisco original and provides identical form factor conversion from QSFP+ to SFP+. It supports 10 Gigabit Ethernet and 1 Gigabit Ethernet via any compliant SFP+ or SFP module and is plug-and-play compatible with Cisco QSFP platforms.

Q: Which Cisco platforms support this adapter?
A: The adapter is designed for QSFP+ platforms including switches and line cards with 40G QSFP ports. Confirmed compatibility includes the Catalyst 9600 platform with C9600-LC-24C line cards. The adapter allows SFP-based 10G or 1G optics to be used on QSFP ports, but platform-specific limitations may apply. Consult your switch documentation for supported configurations, as some platforms restrict adapter use on adjacent ports or ports configured for 100G.

Q: Can I use any SFP+ or SFP module in this adapter?
A: The adapter supports all MSA-compliant SFP+ modules for 10 Gigabit Ethernet including 10GBASE-SR, LR, ER, ZR, and DWDM variants, as well as 10G copper DAC and active optical cables. It also supports several 1 Gigabit Ethernet SFP modules such as 1000BASE-T and 1000BASE-SX. The adapter is a passive electrical converter, so the reach, fibre type, and connector requirements are determined by the SFP+ or SFP module you install.

Q: Does this adapter pass through digital diagnostics monitoring from the installed SFP+ module?
A: Yes. The adapter includes a 2-wire I2C serial interface compliant with SFF-8436 that allows the host platform to communicate with the EEPROM of any installed SFP+ module. If the SFP+ supports DDM or DOM, the host can read temperature, voltage, transmit power, receive power, and other diagnostic parameters exactly as it would if the SFP+ were installed in a native SFP+ port.

Q: What are the electrical and thermal characteristics of this adapter?
A: The adapter operates over a case temperature range of -20°C to 85°C, suitable for commercial and extended-temperature environments. It requires 3.15V to 3.45V supply voltage from the host QSFP+ port. The design features 100-ohm differential impedance, low insertion loss, and all-metal housing for EMI shielding and heat dissipation. The adapter itself consumes minimal power as a passive device, with total power draw determined by the installed SFP+ module.
