The Cisco 1000BASE-EX SFP Transceiver Module, Model GLC-EX-SMD, is a high-performance, hot-swappable input/output device engineered to provide reliable Gigabit Ethernet connectivity across long-distance single-mode fiber (SMF) optical networks. Operating at a nominal wavelength of 1310 nm, this transceiver is capable of transmitting data over distances up to 40 kilometers on standard Single-Mode Fiber (G.652) without requiring external signal amplification, making it ideal for interconnecting remote buildings, enterprise campuses, and regional data centers.
Equipped with Digital Optical Monitoring (DOM) support (indicated by the 'D' and 'SMD' nomenclature), the GLC-EX-SMD provides real-time diagnostic monitoring of critical transceiver parameters, including optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage. Designed to support an extended operating temperature range, it ensures high operational stability across diverse thermal environments. It features a standard dual LC/PC connector interface and complies fully with IEEE 802.3z 1000BASE-EX standards and Cisco quality controls.
Key Features & Advanced Capabilities:
Long-Distance Gigabit Connectivity: Enables high-speed 1 Gbps Ethernet data transmission over single-mode optical fiber spanning up to 40 km.
1310 nm Laser Optics: Utilizes high-reliability optical laser technology operating at 1310 nm to minimize modal dispersion and signal attenuation over extended reaches.
Digital Optical Monitoring (DOM): Integrated diagnostic features allow real-time tracking of optical power levels, temperature, and voltage for proactive network management.
Extended Operating Temperature (SMD): Engineered to operate reliably in a wide thermal range, accommodating unconditioned wiring closets or industrial environments.
Hot-Swappable Architecture: Allows seamless installation, removal, or replacement in live Cisco switches, routers, and modular slots without network downtime.
Industry Standards Compliance: Compliant with Small Form-Factor Pluggable (SFP) Multi-Source Agreement (MSA) and IEEE 802.3z Gigabit Ethernet standards.
