Home Networking Transceiver Cisco OC-3 SR 155Mbps Single Mode SFP Transceiver Optics

Cisco OC-3 SR 155Mbps Single Mode SFP Transceiver Optics

Brand:
Cisco

The Cisco OC-3 SR SFP is a 155 Mbps SONET/SDH optical transceiver designed for short-reach single-mode fiber links. It is built for carrier-grade transport environments where synchronized, low-latency, and highly stable optical communication is required for legacy telecom and enterprise backbone systems.

OVERVIEW

  • The Cisco OC-3 SR 155Mbps Single Mode SFP transceiver is engineered for SONET/SDH synchronous optical transport networks, delivering reliable 155 Mbps connectivity over single-mode fiber in short-reach deployments. It is optimized for environments requiring precise timing, deterministic performance, and carrier-grade reliability in legacy telecom architectures.
  • Within Cisco’s optical transport portfolio, this SR variant supports critical aggregation and backbone links where SONET/SDH infrastructure remains in active use. Compared to Ethernet-based SFP modules, it is designed specifically for synchronous transport systems, ensuring stable clocking and predictable latency performance. This makes it essential for telecom operators and enterprises that continue to rely on legacy optical transport systems while gradually transitioning toward IP-based infrastructure modernization.

USE CASES

  • Telecom carrier SONET/SDH backbone links
  • Short-reach metropolitan transport networks
  • Government secure communication infrastructure
  • Mobile network legacy backhaul systems
  • Banking leased-line optical connectivity
  • Utility and energy control communication networks
  • Enterprise WAN optical aggregation layers
  • Broadcast transmission infrastructure
  • Railway signaling and communication systems

KEY FEATURES

  • OC-3 / STM-1 SONET/SDH compliant optical transceiver
  • 155 Mbps synchronous transport data rate
  • Short-reach single-mode fiber connectivity
  • Designed for carrier-grade telecom environments
  • Supports deterministic timing and synchronization
  • Low-latency optical transmission performance
  • LC duplex fiber connector interface
  • Hot-swappable SFP form factor
  • Optimized for legacy transport networks
  • Stable performance for mission-critical services
  • Enables gradual migration to IP-based networks
  • Reduces infrastructure replacement cost and risk

TECHNICAL SPECIFICATIONS

  • Brand: Cisco
  • Product Type: Optical SFP Transceiver Module
  • Standard: OC-3 / STM-1
  • Data Rate: 155 Mbps
  • Fiber Type: Single-Mode Fiber (SMF)
  • Reach Category: Short Reach (SR)
  • Application: SONET / SDH Transport Networks
  • Connector Type: LC Duplex
  • Form Factor: Hot-swappable SFP
  • Network Type: Synchronous Optical Transport
  • Use Case: Carrier-grade telecom and enterprise backbone

WHY CHOOSE THIS PRODUCT?

  • Organizations choose the Cisco OC-3 SR SFP when they require stable, synchronized optical transport for legacy SONET/SDH systems over short distances using single-mode fiber. It ensures reliable service continuity in telecom-grade environments where timing accuracy is critical.
  • Unlike Ethernet SFP modules, this OC-3 SR transceiver is purpose-built for synchronous transport networks, providing deterministic timing and carrier-class stability. It supports infrastructure longevity, reduces migration risk, and enables phased modernization of telecom and enterprise backbone networks without disrupting existing services.
