QSFP Modules

A QSFP module is a hot-pluggable optical transceiver built for 40G and 100G links in data centre, campus and service provider networks. As an exporter of original, brand-new network equipment, Hui Tong supplies QSFP and QSFP28 optics alongside the switches and routers they plug into, so importers, distributors and system integrators can source the whole link from one supplier.

What This Product Family Covers and Who Buys It

The QSFP family on this site covers 40G QSFP+ and 100G QSFP28 transceiver modules used to populate uplink and backbone ports on data centre and enterprise switches. QSFP+ (40G) and QSFP28 (100G) share the same physical form factor but run at different lane speeds, so the module must match the port rating of the switch platform. QSFP ports can also be split with breakout cables — for example, a 40G port fanned out to four 10G links, or a 100G port to four 25G links — which makes QSFP optics a flexible building block for mixed-speed networks.

Typical buyers are network equipment distributors, system integrators and IT procurement teams specifying optics against a known switch bill of materials. Orders range from single units for spares and testing to project quantities.

Related hardware context: the EX4600-40F-AFO switch supplied on this site provides 4x 100G QSFP28 uplink ports. We source 40G and 100G optics to match the switch platform, so uplink modules and the switch itself can be ordered together.

Selection and Sourcing Notes

When specifying a QSFP module, confirm three things against your switch data sheet: the port speed (40G QSFP+ versus 100G QSFP28), the reach and fibre type required, and whether the port will be used as a single link or with a breakout cable. Ports rated for QSFP28 generally accept QSFP+ 40G modules, but you should always verify compatibility with the platform before ordering.

• Minimum order from 1 unit — suitable for spares, lab testing or full project quantities.
• Payment terms: T/T, D/P and D/A.
• Every module is covered by a 1-year warranty.
• Supplied from offices and warehouses in Shanghai, Beijing, Wuhan and Shenzhen, and exported to markets in North America, Europe, the Middle East, Southeast Asia, Africa and Oceania.

All equipment is original and brand-new. Hui Tong is a supplier and exporter, not a manufacturer and not an authorized distributor of any brand.
