BlueOptics JH420A-BO sieťový transceiver modul, optické vlákno, 100000 Mbit/s, QSFP28

The BlueOptics JH420A-BO network transceiver module is a QSFP28 fiber-optic pluggable designed for 100000 Mbit/s (100G) links. Constructed in an aluminium housing and weighing approximately 40 g, this module implements the QSFP28 electrical and mechanical form factor and supports single-mode fiber connections with an MPO/MTP interface according to MSA specifications. It is intended for use in high-density network environments such as data centers and enterprise aggregation layers where reliable 100G connectivity is required.

Advantages

The module provides 100G data transfer capability with QSFP28 compatibility and uses single-mode optical transmission for low-loss, long-reach links up to around 2 kilometres when used with appropriate single-mode fiber. Built to MSA mechanical and electrical standards, it offers interoperability with hardware platforms that accept QSFP28 transceivers. Digital diagnostics monitoring (DDM/DOM) support allows remote monitoring of key parameters such as supply voltage, laser bias current, optical transmit/receive power and temperature, simplifying maintenance and troubleshooting. The aluminium enclosure and selected optical/electronic components provide extended operational lifetime and stable performance in rack-mounted network equipment.

Suitable for

• High-density 100G uplinks between switches in data centers
• Interconnects between aggregation and core network devices
• High-performance storage networks and SAN interconnects
• Long-reach single-mode fiber links within campus or metro environments (up to ~2 km with appropriate fiber)

Key specifications

• Interface type: QSFP28
• Maximum data transfer rate: 100000 Mbit/s (100G)
• Optical connector: MPO/MTP (multifibre parallel interface)
• Fiber type: Single-mode fiber support (PSM4/100GBASE-PSM4 protocol compatible)
• Typical reach: up to approximately 2 kilometres over single-mode fiber (dependent on link design)
• Form factor: QSFP28 pluggable module
• Housing material and colour: aluminium
• Weight: ~0.04 kg
• Digital diagnostics: DDM/DOM compliant (MSA SFF-8472)

How to use

Insert the QSFP28 module into a compatible QSFP28 port on a switch, router or other network device while the host device is powered according to the vendor’s hot-plug guidance. Connect an MPO/MTP patch cord to the module and route the single-mode fiber to the remote transceiver or patch panel. Ensure both ends use compatible transceivers and the correct fiber type and polarity. Verify link status through the host device and use the DDM/DOM interface to monitor optical power, temperature and other diagnostics. Follow your equipment vendor’s procedures for firmware, port configuration and any required vendor compatibility settings.

Recommendations

Use high-quality MPO/MTP single-mode patch cords and follow proper fiber handling practices to maintain signal integrity. Confirm that the network hardware supports QSFP28 modules and DDM if you need remote diagnostics. For production deployments, perform link testing and, if possible, request a test sample to validate interoperability and reach within your specific network environment.
