Cisco CVR-QSFP-SFP10G 40G QSFP+ to 10G SFP+ QSA Adaptor Module 74-9474-02

This Cisco adaptor module converts a single 40 Gigabit QSFP+ port into a single 10 Gigabit SFP+ or 1 Gigabit SFP port. It features a passive electrical lane-mapping architecture that routes lane 0 of the four available 40G channels directly to the SFP+ receptacle while terminating the other three lanes. The hot-swappable design allows insertion or removal without disrupting network operations.

Key Features:
- Adapter Type: QSFP+ to SFP+ converter
- Input Form Factor: 40 Gigabit QSFP+ male connector
- Output Form Factor: 10 Gigabit SFP+ / 1 Gigabit SFP female receptacle
- Supported Data Rates: 1.25 Gbps up to 10.31 Gbps
- Compliant with IEEE 802.3Ba, SFF-8436 (QSFP+), and SFF-8431/SFF-8432 (SFP+) standards
- Supports Digital Optical Monitoring (DOM) via integrated DDMI pass-through
- Built-in microcontroller enables I2C register interfacing for network management

Physical & Environmental:
- Durable all-metal housing reduces electromagnetic interference
- Weight: Approximately 100 grams
- Dimensions: 13.5 mm (H) x 18.4 mm (W) x 78 mm (D)
- Operating Temperature: 0°C to 70°C
- Multi-Source Agreement (MSA) and Trade Agreements Act (TAA) compliant

Compatibility:
- Supports various SFP+ optics including SFP-10G-SR, LR, ER, ZR, and DWDM
- Compatible with 10G Direct Attach Copper (DAC) and Active Optical Cables (AOC)
- Supports select 1 Gigabit Ethernet SFP transceivers such as GLC-T and GLC-SX-MM
- Requires network OS (e.g., Cisco IOS XE, NX-OS) with breakout configuration for link initialization

Ideal for optimising port layouts in data centres and enterprise environments.
