SFP transceiver module BlueOptics MGB-TLB10-BO Fiber optic LC Aluminium 20g

The BlueOptics MGB-TLB10-BO is an SFP fiber optic transceiver module designed for 1000BASE-BX-D single-mode links. The module uses an LC simplex connector and is housed in an aluminium enclosure, providing a compact 20 g unit for insertion into SFP ports of switches, routers and other network devices. It implements a fixed-wavelength pair with a transmitter and receiver suitable for single-fiber bidirectional operation, supports common Ethernet and fibre-channel protocols up to 1.25 Gbps and is intended for metropolitan and campus links over distances up to 20 km when used with appropriate single-mode fiber.

Advantages

The module follows MSA SFP mechanical and electrical standards for wide compatibility and supports digital diagnostic monitoring (DDM/DOM) for real-time reporting of supply voltage, laser bias current, transmit power, receive power and temperature. Construction with aluminium housing and proven optical components ensures mechanical robustness and thermal stability while keeping the module lightweight. Designed and tested for interoperability with major hardware platforms that accept the original compatible transceiver, it provides predictable behaviour in mixed-vendor environments and long operational lifetime.

Suitable for

• Single-mode fiber backbone links up to 20 km
• Gigabit Ethernet (1000BASE-BX-D) and similar high-speed optical protocols
• Network switches, routers, storage systems and media converters with SFP slots
• Environments requiring DDM/DOM monitoring for remote diagnostics

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: up to 1.25 Gbps
• Optical mode: single-mode fiber, bidirectional (single-fiber, different wavelengths Tx/Rx)
• Connector: LC simplex
• Nominal reach: up to 20 km (with appropriate single-mode fiber)
• Housing material and colour: aluminium
• Weight: approximately 20 g
• Digital diagnostics: DDM/DOM (compliant with SFF-8472) for real-time monitoring

How to use

Insert the SFP transceiver into a compatible SFP slot on the network device while the device is powered according to the vendor instructions. Connect a single-mode LC patch cord to the LC simplex port. For bidirectional BX operation, ensure the transmitter and receiver wavelengths correspond to the remote transceiver (e.g., 1310 nm transmit / 1550 nm receive or as specified by the equipment). Verify link status on the host device and check digital diagnostic values if supported by the hardware to confirm proper operation and optical power levels. Follow standard ESD precautions during handling and installation.

Usage recommendations

Use high-quality single-mode fiber and LC patch cords matched to the required wavelength plan and maintain clean connector endfaces. Confirm that the hosting hardware supports DDM/DOM if remote diagnostics are required. For best reliability, operate the transceiver within the device vendor’s specified temperature and power ranges and perform periodic monitoring of optical power and temperature via DDM when available.
