Designed for interoperability with QSFP+ ports, it enables short-reach multimode fiber connectivity for server uplinks, switches and aggregation links.

## Long description

The EXTREME 40G-SR4-QSFP150M is a fiber-optic QSFP+ network transceiver module designed for 40 Gbps short-reach multimode links. Operating at 850 nm, it provides high-bandwidth parallel fiber connectivity for data center and enterprise environments. The module is intended for interoperability with QSFP+ ports and supports standard MPO/MTP-style parallel fiber connections used for server uplinks, top-of-rack switches and aggregation links.
Advantages
This QSFP+ transceiver supports 40 Gbps aggregate throughput while using established 850 nm VCSEL-based optics for short-reach multimode fiber, delivering reliable signal quality over typical data center distances. Its compact QSFP+ form factor enables high-density deployment in switch and server line cards. The module is engineered to meet standard electrical and optical interfaces for broad compatibility with QSFP+ ports, simplifying upgrades from 10 G to 40 G links without extensive cabling changes.
Suitable for
 Top-of-rack and leaf-spine switch uplinks in data centers
 Server to switch high-bandwidth connections
 Aggregation links between access and core switch layers
 Short-reach multimode fiber installations (MPO/MTP parallel fiber)
Key specifications
 Data rate: 40 Gbps aggregate (4x10 Gbps lanes)
 Wavelength: 850 nm
 Connector type: MPO/MTP-style parallel fiber interface
 Optical reach: short-reach multimode (typical distances depend on fiber type and modal bandwidth)
 Form factor: QSFP+ (quad small form-factor pluggable)
 Compatibility: designed for QSFP+ ports supporting 40G-SR4 optics
How to use
Insert the EXTREME 40G-SR4-QSFP150M module into a compatible QSFP+ port on a switch, router or network interface card. Ensure the host device is powered down or supports hot-plugging per the equipment manual before insertion. Connect an MPO/MTP parallel multimode fiber cable between the module and the matching transceiver or patch panel, observing correct fiber polarity and MPO key orientation. After physical installation, verify link status through the host device management interface and confirm expected throughput and error statistics.
Usage recommendations
Use OM3 or OM4 multimode fiber for optimal reach and performance; verify fiber type and channel loss budget prior to deployment. Maintain clean optical connectors and follow ESD handling procedures when installing the QSFP+ module. Monitor link health via switch diagnostics and replace optics if persistent errors or signal degradation are observed.
