Plug-and-play form factor simplifies installation and replacement while maintaining interoperability with Juniper equipment.

## Long description

The CBO QSFP28 100G 850nm transceiver compatible with Juniper is a multimode short-range optical module designed for 100 Gigabit Ethernet links. Operating at an 850 nm wavelength, this QSFP28 form-factor transceiver supports high-bandwidth connectivity between switches, routers and servers in data center and enterprise network environments. The plug-and-play design enables straightforward insertion into compatible QSFP28 ports and is intended to maintain interoperability with Juniper network equipment.
Advantages
This transceiver provides a compact QSFP28 form factor that consolidates four lanes of 25 Gbps signaling to deliver 100 Gbps total throughput while minimizing port density. The 850 nm VCSEL-based optics are optimized for multimode fiber and short-reach links, offering reliable performance for intra-data-center connections. Designed to be compatible with Juniper hardware, the module simplifies upgrades and replacements by supporting standard electrical and optical interfaces associated with 100 Gigabit Ethernet.
Suitable for
Short-reach 100 Gigabit Ethernet links within data centers
High-throughput connections between top-of-rack and spine switches
Server-to-switch aggregation over multimode fiber
Network equipment upgrades and port density consolidation
Key specifications

How to use
Before installation, verify that the target device supports QSFP28 modules and that multimode fiber cabling is in place. Power down or follow hot-swap safety guidelines for your Juniper-compatible device, then align and insert the transceiver into a QSFP28 port until it seats securely. Connect the MPO/MTP multimode fiber cable between transceiver ports as required. After insertion, confirm link status and interface configuration in the network device management console; the module is intended for plug-and-play operation with standard 100G Ethernet settings.
Usage recommendations
Use OM3 or OM4 multimode fiber for best short-range performance, maintain clean fiber connectors to avoid signal loss, and observe manufacturer-recommended operating temperature and handling practices to ensure reliable operation in data center environments.
