Optický transceiver modul BlueOptics JH679A-BO QSFP MTP/MPO

The BlueOptics JH679A-BO QSFP MTP/MPO is a 40G fiber optic transceiver module designed for high-speed multimode applications. It uses a QSFP interface and an MTP/MPO connector to transmit and receive optical signals at 850 nm, supporting 40GBASE‑SR4 links over multimode fiber. Constructed with an aluminium housing and weighing approximately 20 g, the module is compact and compatible with systems that accept HPE JH679A‑type QSFP transceivers. The module is suitable for Ethernet, Fibre Channel over Ethernet and SDH/SONET environments that require short‑reach 40 Gbps connectivity.

Advantages

The module follows MSA standards for QSFP form factor and MPO/MTP connectivity, enabling interoperability with a wide range of network equipment while maintaining consistent optical characteristics. Built from high‑quality components, it offers digital diagnostic monitoring (DDM/DOM) capability for real‑time insight into supply voltage, laser bias current, transmitted power, received power and temperature. Its aluminium enclosure provides physical durability and a lightweight profile simplifies handling and installation.

Key specifications

How to use

Insert the QSFP transceiver into a compatible QSFP port of a switch, router or other networking device, ensuring the module aligns with the port latch and seats securely. Connect an MTP/MPO multimode fiber cable to the module's connector, observing correct polarity and fibre ribbon mapping for SR4 parallel links. Verify link status via the host device and, if available, access DDM/DOM information through the equipment management interface to monitor optical and electrical parameters. When removing the module, power down or follow hot‑swap procedures recommended by the host device and use the release tab to extract the transceiver.

Recommendations

Use OM3 or OM4 multimode fiber patch cords and properly routed MPO/MTP connections to achieve specified reach and signal quality. Confirm host device compatibility with HPE JH679A‑type QSFP modules and ensure the management system supports DDM/DOM if remote diagnostics are required. Handle the transceiver by the housing, keep the connector dust caps on when not in use, and follow ESD precautions during installation and removal.
