## Long description

The BlueOptics SLC120-DDM-BO is a high-performance SFP fiber optic transceiver module engineered for reliable 100BASE-ZX networking applications. Operating at a wavelength of 1550 nm, this module facilitates stable data transmission at speeds up to 155 Mbit/s. Designed for long-range connectivity, it supports distances of up to 120 km over singlemode fiber, making it an essential component for extending network reach in professional environments.
Advantages
This transceiver module offers exceptional durability thanks to its robust metal housing, which protects internal components during operation. The inclusion of Digital Diagnostics Monitoring (DDM) allows network administrators to monitor real-time parameters such as optical output power, input power, and temperature, ensuring proactive maintenance and high uptime. Its compact SFP form factor ensures compatibility with a wide range of networking equipment, while the low power consumption and standard operating voltage make it an energy-efficient choice for data centers and enterprise networks.
Suitable for
Long-distance network backhaul connections
Connecting remote network segments up to 120 km
Professional 100BASE-ZX fiber optic infrastructure
Enterprise-grade data transmission over singlemode fiber
When it may not be suitable
This module is not designed for high-speed applications exceeding 155 Mbit/s, such as Gigabit Ethernet or 10G networks. Furthermore, it is intended for use with singlemode fiber optic cabling and will not function with multimode fiber infrastructure.
Key specifications
Data transfer rate: 155 Mbit/s
Wavelength: 1550 nm
Maximum distance: 120 km
Connector type: SFP
Input voltage: 3.3 V
Housing material: Metal
How to use
To install the BlueOptics SLC120-DDM-BO, ensure that your networking device is powered on or follows the manufacturer's specific hot-swap guidelines. Insert the module into an available SFP port until it clicks into place. Connect the appropriate singlemode fiber optic cable with an LC-Duplex connector to the module. Once connected, the device should automatically detect the transceiver, allowing for immediate data transmission. Always ensure the fiber connectors are clean before insertion to maintain signal integrity.
What to consider before purchase
Verify that your switch or router supports 100BASE-ZX SFP modules.
Ensure the existing fiber infrastructure is singlemode.
Check that the required link distance does not exceed 120 km.
Confirm that the device operating temperature range is compatible with your environment.
Usage recommendations
For optimal performance and longevity, avoid touching the optical interface of the transceiver. Always use protective dust caps when the module is not connected to a fiber cable to prevent dust accumulation and signal degradation.
