LC Duplex 1000BASE-SX SFP Module (1310 nm, 2 km) – DOM Supported sfp module
Highlights
- 1G SFP module with 1310 nm optics for ~2 km reach.
- LC duplex connector, DOM support, and hot-swappable design.
- Programmed for Cisco compatibility; ideal for replacements.
Product Description
This hot-swappable SFP transceiver is designed for 1000BASE-SX applications, supporting short- to medium-reach fiber connections with a typical transmission distance of up to 2 km. It features a 1310 nm optical transmitter with a duplex LC interface and supports Digital Optical Monitoring (DOM) for real-time performance tracking. Compatible with Cisco and similar platforms, it meets MSA standards for easy integration and field replacement.
Key Features
- Hot-pluggable SFP design – Enables easy installation and replacement without system shutdown.
- 1310 nm wavelength with LC duplex interface – Optimized for fiber runs up to 2 km.
- Digital Optical Monitoring (DOM/DDM) – Provides real-time diagnostics including Tx/Rx power, temperature, and laser bias current.
- Cisco-compatible firmware – Ready for use in Cisco and other vendor devices (check compatibility prior to deployment).
- Low power consumption & robust metal housing – Ensures reliable operation in demanding environments.
