Cisco Compatible QSFP-40G-SR4 40GBASE-SR4 QSFP+ Optical Transceiver (MPO, 850nm, 100m)
Product Overview
The Cisco compatible QSFP-40G-SR4 optical transceiver is a high-performance 40Gbps module designed for short-range data transmission over multimode fiber (MMF). Operating at an 850nm wavelength, it supports distances up to 100 meters on OM3 fiber and 150 meters on OM4 fiber.
This QSFP+ module uses an MPO/MTP multi-fiber connector and transmits data over 4 parallel lanes (4x10G), making it ideal for high-density data center environments requiring fast and reliable 40G connectivity.
Key Features
- Supports aggregate data rate of 40Gbps (4x10Gbps lanes)
- 850nm VCSEL array for parallel optical transmission
- Transmission distance up to 100m (OM3) / 150m (OM4)
- MPO/MTP 12-fiber connector
- Fully compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4
- Hot-pluggable QSFP+ form factor
- Low power consumption (<1.5W)
- Built-in Digital Diagnostic Monitoring (DDM/DOM)
- High port density for data center applications
- 100% compatible with Cisco devices (custom coding available)
- RoHS compliant and Class 1 laser safety certified
