MaxLink 1.25G SFP Optical Module ML-S3155-3 WDM BiDi Single-Mode Tx 1310/Rx1550nm 3km LC DDM

The MaxLink 1.25G SFP optical module model ML-S3155-3 is a reliable transceiver designed for high-speed fiber optic communication networks. It facilitates seamless data transmission over single-mode fiber infrastructure, making it an efficient solution for enterprise networks, data centers, and telecommunication links. Equipped with advanced WDM BiDi technology, this module enables simultaneous data transmission and reception over a single optical fiber strand, optimizing available network bandwidth and infrastructure costs.

Advantages

This SFP module provides efficient WDM BiDi bidirectional communication over a single fiber strand, which significantly reduces cabling complexity and deployment expenses. The inclusion of Digital Diagnostics Monitoring (DDM) allows network administrators to monitor critical operational parameters in real time, ensuring high reliability and proactive maintenance. With a data rate of 1.25 Gbps and a transmission range of up to 3 kilometers, it delivers stable and consistent performance for short-to-medium distance fiber connections.

Suitable for

• Connecting switches and routers in enterprise local area networks
• Extending network reach across corporate campuses up to 3 kilometers
• Telecommunication applications requiring single-fiber BiDi transmission
• Data center interconnections using LC fiber cabling

When it may not be suitable

This optical module is not designed for multi-mode fiber optic cabling infrastructures and will not function correctly without compatible single-mode fiber. It is also not suitable for long-distance transmissions exceeding 3 kilometers or for networks that require data rates significantly higher than 1.25 Gbps.

Key specifications

• Data transfer rate of 1.25 Gbps
• WDM BiDi bidirectional technology
• Single-mode fiber compatibility
• Transmitter wavelength of 1310 nm
• Receiver wavelength of 1550 nm
• Maximum operating distance of 3 km
• Single LC optical connector
• Digital Diagnostics Monitoring (DDM) supported

How to use

Ensure that the networking device is powered off before handling the optical module. Gently insert the SFP transceiver into the designated slot on your switch, router, or media converter until it clicks securely into place. Connect the appropriate single-mode fiber optic cable with an LC connector to the module port. Power on the network device and verify the link status and transceiver parameters through the network management interface utilizing the DDM functionality.

What to consider before purchase

• Verify compatibility with your existing network hardware and switches
• Confirm that your cabling infrastructure utilizes single-mode fiber
• Check that the paired network device uses matching BiDi wavelengths such as Tx 1550/Rx 1310 nm
• Ensure the required transmission distance does not exceed 3 kilometers

Always handle optical modules with ESD safety precautions, keep dust caps attached when not in use to prevent optical contamination, and ensure wavelength pairing matches the opposing transceiver.
