Cisco SFP-10G-BX100D Compatible SFP+ 10GBASE-BX100-D BiDi 1550nm-TX/1490nm-RX 100km DOM Simplex LC/UPC SMF Optical Transceiver Module

The Cisco SFP-10G-BX100D is a Bidirectional (BiDi) SFP+ optical transceiver module designed for 10 Gigabit Ethernet (10GbE) applications. It supports 10GBASE-BX100-D standards, enabling long-distance communication over a single strand of single-mode fiber (SMF). Here’s a detailed breakdown:

Key Features:

1. BiDi Technology:
   • Transmits and receives data over one fiber strand using separate wavelengths:
     • TX (Transmit): 1550nm
     • RX (Receive): 1490nm
2. Transmission Distance:
   • Supports up to 100 kilometers (km) over single-mode fiber (SMF).
3. Data Rate:
   • 10 Gbps for high-speed connectivity in demanding environments.
4. DOM (Digital Optical Monitoring):
   • Monitors real-time parameters like temperature, voltage, and TX/RX power for proactive network management.
5. Connector Type:
   • Simplex LC/UPC connector, optimized for single-strand BiDi applications.
6. Compliance:
   • Compliant with 10GBASE-BX100-D standards and Cisco compatibility.
7. Industrial-Grade Design:
   • Operates in extended temperature ranges (-40°C to 85°C) for harsh environments.

Applications:

• Telecommunications:
  • Long-haul metro networks requiring 10Gbps over ultra-long distances (100km).
• Enterprise Backbones:
  • High-speed connections between geographically dispersed offices.
• Data Centers:
  • Cost-effective fiber infrastructure by halving fiber usage (single-strand vs. duplex).
• Industrial Networks:
  • Rugged environments like oil/gas, utilities, or outdoor deployments.

Benefits:

• Cost Efficiency:
  • Reduces fiber infrastructure costs by 50% (single-strand deployment).
• Long Reach:
  • 100km range eliminates the need for repeaters in most scenarios.
• Cisco Compatibility:
  • Seamless integration with Cisco switches/routers (e.g., Nexus, Catalyst, ASR series).
• Future-Proofing:
  • Supports high-bandwidth applications like video streaming, cloud services, and IoT.

Typical Use Case:

• Connecting two Cisco switches across a metropolitan area (e.g., data center to remote office) using a single fiber strand, reducing cabling complexity and cost.

Compatibility Notes:

• Paired Deployment:
  • Requires a matching Upstream (U) module (e.g., SFP-10G-BX100U) with reversed wavelengths (TX: 1490nm / RX: 1550nm) at the other end.
• Cisco Devices:
  • Compatible with Cisco platforms supporting SFP+ and 10GBASE-BX standards (verify device-specific compatibility).

Standards Compliance:

• IEEE 802.3ah (10GBASE-BX-D)
• SFF-8472 (DOM)
• RoHS compliant
