Fiber optic SFP transceiver BlueOptics GMLC2-DDM-BO LC Aluminium 20g

The BlueOptics GMLC2-DDM-BO is a fiber optic SFP transceiver designed for high-speed single‑fiber optical links. It features an LC duplex connector, aluminium housing and a lightweight build of approximately 20 g. The module implements 1000BASE‑X transmission characteristics with both transmitter and receiver operating at 1310 nm for multimode fiber, and includes Digital Diagnostics Monitoring (DDM) for real‑time monitoring of optical and electrical parameters when supported by the host device.

Advantages

This SFP transceiver follows industry MSA form‑factor standards and is compatible with equipment that accepts Westermo GMLC2‑DDM style 1000BASE‑X modules. The aluminium housing provides durable mechanical protection while keeping weight low, and the LC duplex interface enables simultaneous send/receive operation on two fibers. Integrated DDM support simplifies remote diagnostics by reporting parameters such as supply voltage, laser bias current, optical output/receive power and module temperature when the host supports DOM/DDM access.

Suitable for

• 1 Gbps Ethernet links over multimode fiber
• Interconnects between switches, routers and storage equipment
• Industrial and enterprise networking sites requiring DDM capability
• Replacement or upgrade of compatible SFP transceivers using LC connectors

Key specifications

• Form factor: SFP (Small Form‑Factor Pluggable)
• Optical wavelength: 1310 nm (transmit and receive)
• Supported protocol: 1000BASE‑X (1.25 Gbit/s line rate)
• Connector type: LC duplex
• Fiber type: multimode fiber compatibility
• Housing material: aluminium
• Weight: approx. 0.02 kg
• Digital Diagnostics Monitoring (DDM) support for real‑time parameter readout

How to use

Install the BlueOptics GMLC2‑DDM‑BO by inserting the SFP module into a compatible SFP port on your switch, router or other network device while the host is powered per the device vendor guidance. Connect LC duplex patch cords to the module’s LC connector, observing correct transmit/receive orientation. If the host supports DDM/DOM, use the device management interface to read diagnostic values for supply voltage, laser current, optical power and temperature. Follow standard electrostatic discharge (ESD) precautions when handling the module and ensure fiber connectors and patch cords are clean before mating to avoid performance degradation.

Recommendations

Verify compatibility with the target hardware and firmware before deployment, and confirm that the receiving equipment supports DDM if you require diagnostic monitoring. Use appropriate multimode fiber patch cords and maintain connector cleanliness. For long‑term reliability, operate the transceiver within the host device’s specified temperature and voltage ranges and schedule periodic inspections of optical power levels and connector condition.
