## Summary description

Compatible IBM BlueOptics QSFP transceiver EB57-BO for 40GBASE-SR4 links. MPO/MTP connector, multimode fiber, four 850 nm lanes supporting up to 150 m reach. Designed for data center and high-speed aggregation use, operating temperature 0–70°C. Suitable for short-reach 40 Gbps Ethernet connections and switch uplinks.

## Long description

The QSFP Transceiver BlueOptics EB57-BO 40GBASE‑SR4 is a short-reach optical module designed for 40 Gbps Ethernet links in data center and high-density aggregation environments. It uses multimode fiber with an MPO/MTP interface and four 850 nm optical lanes to deliver up to 150 meters of reach over suitable multimode fiber. The module is intended for use in switch uplinks, server interconnects and patching within racks and between adjacent racks, and is specified to operate in ambient temperatures from 0 to 70°C.
Advantages
The transceiver supports 40GBASE-SR4 signaling using four parallel 850 nm lanes, providing a compact QSFP form factor that consolidates multiple channels into a single port. The MPO/MTP connector simplifies multi‑fiber cabling and reduces trunk complexity compared with multiple LC connections. Its multimode design and 150 m reach make it suitable for typical data center topologies where short-distance, high-bandwidth links are required. Rated operating temperature ensures compatibility with standard equipment racks and cooled server rooms.
Suitable for
40 Gbps switch uplinks within data centers
Server-to-switch high-bandwidth interconnects over multimode fiber
Top-of-rack to aggregation switch connections up to 150 m
High-density installations using MPO/MTP trunk cabling
When it may not be suitable
This QSFP transceiver is intended for short-reach multimode fiber links and is not suitable for long-reach or single-mode applications. It will not support distances beyond the specified 150 m over multimode fiber, and it does not provide compatibility with single-fiber single-mode optics or CWDM/DWDM systems.
Key specifications
Data rate: 40 Gbps (40GBASE-SR4)
Fiber type: Multimode fiber (MMF)
Wavelength: 4 × 850 nm lanes
Connector: MPO/MTP multi-fiber connector
Maximum reach: Up to 150 meters on appropriate multimode fiber
Form factor: QSFP (Quad Small Form-factor Pluggable)
Operating temperature range: 0 to 70 °C
How to use
Insert the QSFP transceiver into a compatible QSFP port on the switch or NIC until it seats firmly and the latch engages. Use an MPO/MTP multi-fiber patch or trunk cable to connect to the corresponding MPO/MTP port on the remote device or patch panel. Ensure that the deployed multimode fiber type and modal bandwidth (for example OM3 or OM4) support the required 150 m reach at 40GBASE‑SR4. Observe proper handling procedures for optical transceivers: avoid touching the fiber endfaces, keep dust caps on when not connected, and verify link status through the network device interface after installation.
What to consider before purchase
Verify that your switches or network devices support QSFP form-factor transceivers and 40GBASE‑SR4 signaling.
Confirm the multimode fiber grade (OM3/OM4) and channel length to ensure the 150 m reach is adequate.
Check MPO/MTP cabling infrastructure and polarity for compatibility with parallel optics wiring.
Ensure ambient operating temperatures align with the 0–70°C range of the module.
Usage recommendations
Use OM4 multimode fiber for best margin when approaching the 150 m limit, maintain clean connectors and proper polarity in MPO/MTP trunks, and verify link status and error counters after deployment to confirm stable 40G operation.
