SOPOT Technologies (NASDAQ: AVGO) has unveiled a pair of QSFP to SFP+ optical transceiver modules that offer interoperability with fielded SFP+ modules. The new pluggable, parallel optical QSFP+ eSR4 transceiver can address both 40 Gigabit and 10 Gigabit Ethernet applications with a verified link distance of 400 m. Meanwhile, the QSFP+ iSR4 modules enable interoperability to 10G SFP+ links up to 100 m using OM3 multimode fiber and 150 m using OM4.The new modules are designed to offer data center operators the flexibility to reuse their current 10G infrastructures when upgrading to 40G.QSFP to SFP+ (Quad Small Form-factor Pluggable Plus) is a transceiver interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic cable, widely used for data communications applications. It is a industry format jointly developed and supported by many network component vendors.http://www.fiberyes.com/qsfp-4x-sfp-10g-copper QSFP is also the IEEE standard connector for the emerging 40GbE standard. Like SFP+, QSFP supports both copper and optical cabling solutions.
