Cisco 10-1954-01 Extended Temperature Tri-Rate SX/SW SFP

Overview
The Cisco Extended Temperature Tri-Rate SX/SW SFP (part number 10-1954-01) is a rugged, hot-swap optical transceiver designed for high-performance data center and carrier environments that require reliable operation over a wide temperature range. It supports three data rates - 1 Gbps, 2 Gbps and 4 Gbps - on a single Small Form-Factor Pluggable (SFP) module, giving network engineers flexibility to deploy the same hardware across multiple Ethernet standards while reducing inventory complexity.

Key Features

• Tri-rate operation: 1 Gbps, 2 Gbps and 4 Gbps Ethernet
• Extended temperature range: -40 to 85 deg Celsius for harsh industrial sites
• LC duplex connector with standard 9 µm single-mode fiber
• Hot-swap capable for zero-downtime maintenance
• Low power consumption and built-in diagnostics (DOM) for proactive monitoring
• Compliance with Cisco IOS XE and NX-OS platforms

Technical Specifications

• Form factor: SFP
• Wavelength: 1310 nm
• Maximum reach: 10 km on standard single-mode fiber
• Transmit power: -8 to 0 dBm
• Receiver sensitivity: -30 dBm (typical)
• Operating voltage: 3.3 V
• Power draw: 0.8 W max
• Dimensions: 13.4 mm x 56.5 mm x 8.5 mm

Applications
The Extended Temperature Tri-Rate SX/SW SFP is ideal for:

• Metro and long-haul carrier networks that need to support multiple Ethernet speeds on a single fiber link
• Data center interconnects where space and power efficiency are critical
• Industrial automation sites with extreme temperature conditions
• Campus networks upgrading from 1 Gbps to 4 Gbps without replacing transceiver inventory
• Any Cisco Catalyst, Nexus or ASR platform that supports SFP modules

By delivering versatile speed options, robust temperature tolerance, and easy hot-swap installation, this Cisco SFP module helps you future-proof your network while minimizing operational costs.
