With speeds in the data center now increasing from 10 Gbps to 40 Gbps and eventually to 100 Gbps, different optical technologies and cabling infrastructure are required. The QSFP+ transceiver is the dominant transceiver form factor used for 40 Gigabit Ethernet applications. In 2010 the IEEE standard 802.3ba released several 40-Gbps based solutions, including a 40GBASE-SR4 parallel optics solution for MMF. Since then, several engineered solutions have been released, including 40GBASE-CSR4, which is similar to 40GBASE-SR4 but extends the distance capabilities. This article will mainly introduce the typical cabling components and the cabling options for 40Gbps parallel optical modules.

Fiber optic transceivers are devices that both transmit and receive data. Fiber optic transceiver is typically used in computer networks to translate signals between optical and electric networks. In other words, the sending side of it transfers the electrical signals into optical signals, and then transmitted by the fiber, the receiving side transfers the optical signals into electrical signals. This article will introduce the common types of fiber optic transceivers on the market.

SFP Transceiver Module

SFP is short for Small Form-factor Pluggables, unlike GBIC transceiver with SC fiber optic interfaces is with LC interface and the main body size of SFP is only about half of GBIC, which makes SFP space saving. SFP transceiver...
