Starting since April, 2013, we have shipped hundreds of RJ45 copper SFPs with hardened temperature feature to our service provider and government customers after the customer testing.  

The unit complies with IEEE 802.3, 802.3u, and 802.3ab Specifications, conforms to Multi-Source Agreement (MSA) specifications for SFP transceivers, supports IEEE 802.3u and IEEE 802.3ab auto–negotiation features to allow networking equipment to automatically determine and adjust the required settings, operates in extended temperature range of -40° to +85° C, automatically compensates for baseline wander by removing the DC offset from the input signal, assembled with low EMI emissions IC and fully metallic housings, automatic dependent interface (DI) crossover, eliminating the need for crossover cables or cross-wire (MDIX) ports.
