Network transceiver module CBO ET7304-SR-BO QSFP28 100000 Mbit/s 850 nm

The BlueOptics CBO ET7304-SR-BO QSFP28 is a high-density optical transceiver module engineered for short-range multimode fiber connections. Supporting a data rate of 100000 Mbit/s and an 850 nm wavelength, this QSFP28 module consolidates four parallel channels into a single pluggable form factor, enabling compact, high-throughput links in data center and enterprise switching environments. Designed for insertion into compatible QSFP28 ports, it is intended for use where reliable, low-latency 100GbE optical connectivity is required over multimode fiber.

Advantages

The module offers four parallel lanes in a single QSFP28 package, allowing space-efficient deployment and simplified cable management. Operation at 850 nm with multimode fiber is optimized for short-range links, reducing component cost while maintaining high throughput. The pluggable form factor enables hot-swap replacement and quick upgrades without disrupting system operation, and the standardized QSFP28 interface ensures compatibility with a wide range of switches and transceivers that support QSFP28 optics.

Suitable for

• 100 Gigabit Ethernet short-reach connections over multimode fiber (MMF)
• Top-of-rack and spine-switch links in data centers
• High-density aggregation in enterprise switching environments
• Upgrading or replacing QSFP28 ports for increased bandwidth

Key specifications

• Form factor: QSFP28, 4-channel parallel transceiver
• Maximum data rate: 100000 Mbit/s (100 Gb/s)
• Operating wavelength: 850 nm
• Fiber type: multimode fiber (MMF), optimized for short reach
• Typical reach: short-range multimode links (sector-typical distances for 850 nm MMF)
• Hot-pluggable pluggable transceiver for easy replacement

How to use

Install the QSFP28 module into a compatible QSFP28 port on your switch or router, ensuring the module is oriented correctly and seats fully into the cage. Connect suitable multimode fiber patch cables or breakout assemblies matched to the transceiver’s 4-channel parallel configuration. After insertion, verify link status and diagnostic data via the host device’s management interface. For safe removal, follow the host equipment’s hot-swap procedure to avoid disrupting active links.

Recommendations

Use OM3/OM4 multimode fiber and appropriate MPO/MTP or breakout cabling rated for 100 Gb/s to achieve reliable short-range performance. Maintain proper fiber cleanliness and follow manufacturer guidelines for insertion loss and connector handling. Confirm compatibility with the host equipment’s QSFP28 specifications and firmware support before deployment.
