NSComm NS-QSFP-40G-SR4 40G Base-SR4 QSFP+ 850nm 100m MTP/MPO MMF DDM Optical Transceiver Module
NS-QSFP‑40G‑SR4 Transceiver Module | 40 Gbps, 850 nm, MPO/MTP, 100 m – Compatible with All Brands
Product Overview
The NSComm NS-QSFP‑40G‑SR4 is a high-density, parallel-optical transceiver built for 40 Gigabit Ethernet over multimode fiber.
It uses four 10 Gbps lanes, combining to provide a full 40 Gbps data throughput using an 850 nm VCSEL array. This module supports distances up to 100 m on OM3 MMF and up to 150 m on OM4 MMF, using a 12‑fiber MPO/MTP connector.
It is hot‑swappable and complies with IEEE 802.3ba and QSFP+ MSA standards. In addition, it features Digital Diagnostic Monitoring (DDM) for real-time optical performance diagnostics.
This transceiver is designed for universal brand compatibility, perfect for use with equipment from Cisco, Juniper, Arista, Dell, Huawei, HPE Aruba, and more.
