Information About GLC-LH-SM
The GLC-LH-SM operates over single-mode fiber using 1310 nm wavelength for both transmission and reception. It supports a maximum distance of 10 kilometers, making it suitable for campus backbones, metropolitan access, and long-haul connections. This SFP module uses a Fabry-Perot (FP) laser transmitter, offering stable signal performance in standard temperature environments ranging from 0°C to 70°C. It features an optical budget of 13 dB, which ensures reliable operation under typical link loss conditions.
Key Features:
-
1310 nm FP Laser: Provides stable transmission for long-range Gigabit links
-
Single-Mode Fiber Support: Enables links up to 10 km
-
Standard Duplex LC Connector: Simplifies deployment with common SMF patch cords
-
Wide Optical Budget (13 dB): Tolerates typical link losses
-
High Compatibility: Interoperable with Cisco and MSA-compliant equipment
The GLC-LH-SM ensures cost-effective, high-reliability 1G fiber connectivity across extended distances.
