Cisco SFP-10G-ZR-I= - SFP+ Module for SMF

Cisco Part Number: SFP-10G-ZR-I= is a Cisco Multirate 10GBASE-ZR, 10GBASE-ZW and OTU2e SFP+ Module for SMF

The Cisco SFP-10G-ZR-I is a multirate 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e SFP+ module designed for industrial operating temperature ranges. It supports link lengths of up to 70 kilometers on standard Single-Mode Fiber (SMF, G.652) with a fiber chromatic dispersion of 20 ps/(nm*km). The module features a limiting electrical interface receiver that does not require an EDC PHY on the host board and can be plugged into any SFP+ port.

Key specifications include:

• Transmitter wavelength range: 1530 to 1565 nm
• Transmitter optical output power: 0 to 4.0 dBm
• Receiver optical input wavelength: 1260 to 1565 nm
• Receiver sensitivity: -24 dBm (10GE LAN/WAN rates, non-FEC), -27 dBm (OTU2/OTU2e rates, FEC)
• Power consumption: 2 W
• Operating temperature range: Industrial range from -40°C to 85°C, with a cold start at -40°C where optical traffic is not supported from -40°C to -28°C, but other low-speed features remain operational
• Module dimensions: 8.5 x 13.4 x 56.5 mm
• Bail latch color code: Green

The SFP-10G-ZR-I is built according to Cisco specifications and is not part of the official 10 Gigabit Ethernet standard. It is suitable for industrial environments requiring extended temperature ranges and long-distance single-mode fiber connectivity.

Additionally, the SFP-10G-ZR-I is listed as a migration product for the Cisco SFP-10G-ZR and SFP-10G-ZR-S modules, which are reaching end-of-sale on June 10, 2026, with support continuing until June 30, 2031.

This module is supported on various Cisco platforms, including Cisco Catalyst wireless controllers, and is hot-swappable with online insertion and removal capability.
