Glasvezel-transceivermodule BlueOptics JSH-42L3AD3-20-BO SFP LC aluminium

The BlueOptics JSH-42L3AD3-20-BO SFP LC Aluminium is a fiber optic transceiver module designed for single-mode 1000BASE-LX applications. Housed in an aluminium case and featuring an LC duplex connector, this compact SFP module weighs approximately 20 g and delivers up to 1.25 Gbit/s data transfer over single-mode fiber for distances up to 20 km. The module supports simultaneous transmit and receive operation with 1310 nm wavelength for both TX and RX and follows MSA form-factor standards for interoperability with a wide range of networking equipment.

Advantages

The module provides MSA-compliant SFP form-factor compatibility and an LC duplex interface for easy integration into switches, routers and storage hardware that support 1000BASE-LX. Durable aluminium housing offers mechanical protection while keeping component weight low. The BlueOptics transceiver is built using industry-standard optical and electronic components and is tested for compatibility on major platforms to simplify installation and reduce replacement complexity.

How to use

Install the SFP module into a compatible SFP port on your switch, router or storage device following the device manufacturer’s hot-swap or insertion guidance. Connect an LC duplex single-mode fiber patch cable to the transceiver, ensuring correct polarity for transmit and receive fibers. Verify the host device recognizes the module and confirm link status and speed on the network interface. For environments that support digital diagnostics, enable DDM/DOM monitoring in the host system to obtain real-time information such as optical power and temperature if the platform provides that functionality.

Recommendations

Use single-mode LC patch cords of appropriate quality and maintain clean connector endfaces to preserve optical performance. Confirm that the target hardware supports 1000BASE-LX SFP modules and any digital diagnostic features you intend to use. For long-term reliability, avoid mechanical stress on the fiber and maintain appropriate operating temperature and humidity conditions as specified by the host equipment.
