Cisco SFP-25G-ER40-S-I Compatible SFP28 25GBASE-ER 1310nm 40km DOM Duplex LC/UPC SMF Optical Transceiver Module (Industrial)

The Cisco SFP-25G-ER40-S-I is a high-performance SFP28 optical transceiver module designed for 25 Gigabit Ethernet (25GbE) applications. It is compatible with Cisco devices and supports 25GBASE-ER standards, making it suitable for long-distance data transmission over single-mode fiber (SMF). Here’s a detailed breakdown of its features and applications:

Key Features:

1. Form Factor:
   • SFP28 (Small Form-Factor Pluggable 28), which is the same size as SFP+ but supports higher data rates up to 25 Gbps.
2. Wavelength:
   • Operates at 1310nm, which is standard for single-mode fiber applications.
3. Transmission Distance:
   • Supports distances of up to 40 kilometers (km) over single-mode fiber (SMF).
4. Data Rate:
   • Supports 25 Gbps data rates, making it ideal for high-speed network applications.
5. DOM (Digital Optical Monitoring):
   • Provides real-time monitoring of key parameters such as temperature, voltage, TX/RX power, and more, enabling easier network management and troubleshooting.
6. Connector Type:
   • Uses a Duplex LC/UPC connector, which is standard for single-mode fiber connections.
7. Industrial Temperature Range:
   • Designed for industrial environments, operating in a temperature range of -40°C to 85°C (-40°F to 185°F).
8. Compliance:
   • Compliant with 25GBASE-ER standards and compatible with Cisco devices.
9. Low Power Consumption:
   • Energy-efficient design, reducing operational costs in high-density deployments.

Applications:

• Data Centers:
  • Ideal for high-speed interconnects between switches, routers, and servers in data centers.
• Telecommunications:
  • Suitable for long-haul and metro networks requiring 25Gbps connectivity.
• Enterprise Networks:
  • Provides high-speed connectivity for enterprise backbone networks.
• Industrial Environments:
  • Designed to operate reliably in harsh industrial conditions, making it suitable for manufacturing, energy, and outdoor applications.

Benefits:

• High Performance:
  • Delivers reliable 25Gbps connectivity with low latency and high signal integrity.
• Long Reach:
  • Supports distances up to 40km, making it ideal for wide-area networks (WANs) and metro networks.
• Industrial Durability:
  • Built to withstand extreme temperatures and harsh environments.
• Cisco Compatibility:
  • Fully compatible with Cisco switches and routers, ensuring seamless integration into existing networks.

Typical Use Case:

• Deploying this transceiver in a data center or telecom network to connect switches or routers over long distances (up to 40km) using single-mode fiber.

Compatibility:

• Cisco Devices:
  • Compatible with Cisco switches and routers that support SFP28 modules and 25GbE interfaces.
• Standards:
  • Compliant with IEEE 802.3by (25GBASE-ER) and SFF-8402 (SFP28 MSA).
