Transceiver CBO JDSU JQP-04SRAB2 100G QSFP28 850nm

The Transceiver CBO JDSU JQP-04SRAB2 100G QSFP28 850nm is a compact, hot-pluggable optical module designed for short-reach multimode links in data center and enterprise networks. It aggregates four parallel lanes into a single 100 Gb/s QSFP28 interface and operates at an 850 nm wavelength, enabling high-throughput connections between servers, top-of-rack switches and other network devices over multimode fiber.

Advantages

This QSFP28 transceiver supports 100G throughput in a small form factor suitable for high-density racks and switch ports. Its multimode 850 nm optics provide reliable short-reach performance with lower power consumption compared to longer-reach alternatives. The hot-pluggable design simplifies maintenance and upgrades without shutting down equipment, while standard QSFP28 compatibility ensures interoperability with many modern 100G-capable switches and servers.

Key specifications

How to use

Install the transceiver into a compatible QSFP28 port on a switch or server line card while the host device is powered according to vendor guidance for hot-pluggable modules. Connect the multimode fiber patch cable or MPO/MTP breakout harness to the transceiver, ensuring proper polarity and fiber type (OM3/OM4) for the intended reach. Verify link status through the host device management interface and monitor optical diagnostics where supported to confirm signal levels and operating temperature.

Recommendations

For reliable 100G performance, use certified multimode fiber (OM3 or OM4) and follow the switch vendor’s compatibility list. Keep fiber connectors clean and use proper MPO/MTP breakouts for lane mapping when connecting to multiple duplex interfaces. Observe ESD precautions when handling the module and avoid extended operation outside the recommended temperature range to maintain optical stability.
