Optický transceiver modul BlueOptics ET7402-ER4-BO 100000 Mbit/s

The BlueOptics ET7402-ER4-BO is a QSFP28 fiber optic transceiver module engineered for high-speed connectivity in data centers and enterprise networks. Supporting a maximum data transfer rate of 100000 Mbit/s, this compact silver module is designed for use in high-density switch and router ports that accept QSFP28 interfaces. With a lightweight 20 g construction and an MTBF of 1,000,000 hours, it provides a reliable optical link for long-haul or metro connections where QSFP28 form factor and 100 Gb/s bandwidth are required.

Advantages

The module's QSFP28 interface enables four-lane 25 Gb/s electrical signaling aggregated to deliver 100 Gb/s total throughput while maintaining compatibility with QSFP28 ports. Its silver housing and compact design support high port density and efficient heat dissipation in rack equipment. The low weight simplifies handling during installation and replacement, and the high MTBF indicates extended operational reliability under typical network conditions.

Suitable for

• 100 Gb/s uplinks between switches in data center environments
• High-performance network backbone and aggregation links
• Long-reach or metro optical connections (where compatible with ER4 optics)
• High-density QSFP28 port deployments in enterprise or carrier equipment

• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the BlueOptics ET7402-ER4-BO into a compatible QSFP28 port on a switch, router or network interface card following equipment vendor guidelines. Ensure the host device supports 100 Gb/s QSFP28 optics and that any required configuration for a 100 Gb/s optical link (speed, lane mapping, and remote end compatibility) is applied. Connect appropriate single-mode fiber patch cords and verify link status and signal quality using the host device management interface or optical monitoring tools.

Recommendations

Use single-mode fiber suitable for long-reach ER4 optics and observe transceiver handling precautions: avoid touching the optical ferrule, keep protective caps on when unused, and ensure proper electrostatic discharge (ESD) protection during installation. Verify compatibility with the specific network equipment and firmware to ensure correct operation at 100 Gb/s.
