Industrial transceiver can work in harsh extended temperatures, it provide a wider operating temperature of -40~85°C. Industrial transceiver usually include the following types:

Industrial fiber optic transceiver also called as hardened fiber optic transceiver or hardened industrial grade fiber optic transceiver, it refers to the optic transceiver with rugged connectors and extended operation temperature of -40°C to 85°C in an harsh industrial environment, such as industrial fiber media converter or Ethernet Switches for the application of industrial and factory automation,outdoor applications,rail and intelligent transportation systems (ITSs),marine,oil and gas,mining etc. Unlike commercial grade fiber optic transceiver,this ones must be designed with field-hardened components including two optical subassemblies, an electrical subassembly and the housing,and tested to handle operating temperatures between -40°C and 85°C to avoid causing any premature failure of the product.

QSFP aslo called QSFP+, it is stand for Quad (4-channel) Small Form-factor Pluggable Optics Transceiver. It is a compact, hot-pluggable fiber optical transceiver used for 40 Gigabit Ethernet (40GbE) data communications applications. It’s designed according to QSFP+ Multi-source agreement and IEEE802.3ab, they are usually for the application of Data center, 40G Ethernet, Infiniband, and other communications standards.

A small form-factor pluggable (SFP) transceiver is a compact, hot-swappable, input/output transceiver used in data communication and telecommunications networks. SFP interfaces between communication devices like switches, routers and fiber optic cables, and performs conversions between optical and electrical signals. SFP transceivers support communications standards including synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), gigabit ethernet and fiber channel. They also allow the transport of fast Ethernet and gigabit Ethernet LAN packets over time-division-multiplexing-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks.
