Description
Cisco SFP-OC3-MM transceiver modules are small form-factor pluggable (SFP) devices designed for use in Cisco networking equipment. They support Synchronous Optical Network (SONET) OC-3 and Synchronous Digital Hierarchy (SDH) STM-1 data rates over multimode fiber optic cable.
Key features of SFP-OC3-MM transceivers include:
Data rate support: OC-3 (155 Mbps)
Fiber type: Multimode
Reach: Typically up to 2 kilometers
Dual LC/PC connectors: For connection to multimode fiber optic cables
Digital Optical Monitoring (DOM): Enables real-time monitoring of operational parameters like transmit/receive power and temperature
These transceivers are essential components for establishing SONET/SDH or ATM connections over short distances using multimode fiber optic cabling in Cisco networking environments. They provide a reliable and high-performance solution for data transmission within data centers, enterprise networks, and carrier applications.
