Cisco® 100GBASE QSFP (Quad Small Form-Factor Pluggable) transceivers offer customers a wide variety of high-speed, high-density, low-power 100 Gigabit Ethernet connectivity options for data centers, high-performance IT networks, distribution layers , enterprise core, and service provider applications.
QSFP100G modules are the next generation of 100G transceiver module solution based on a QSFP form factor.
Features and Benefits of Cisco QSFP Modules
Hot-swappable input/output device that plugs into a 100G Gigabit Ethernet Cisco QSFP port
Interoperable with other IEEE-compliant 100GBASE interfaces where applicable
Certified and tested on Cisco QSFP-100G ports for superior performance, quality, and reliability
High-speed electrical interface compliant to IEEE 802.3bm
Upgrade Seamlessly From 40Gb or 10Gb
Data center traffic continues to grow, driven by increases in server activity, application density on virtualized servers, and demand for low-latency east-west connections between servers.
When the popular QSFP+ 40Gb bi-directional (BiDi) transceiver was released, it enabled data center operators, for the first time, to upgrade from 10Gb to 40Gb without the need to replace fiber cable infrastructure. The next generation dual-rate BiDi, which has both 40Gb and 100Gb operational modes, offers the same benefits and more.
The Cisco QSFP 40/100 Gb dual-rate BiDi transceiver can function as a 40Gb BiDi, matching its reach of 100m and 150m over OM3 and OM4 multi-mode fiber, respectively. In 100Gb mode, the dual-rate BiDi’s reach is 70m and 100m on OM3 and OM4, respectively. In both modes, the BiDi reach matches its SR4 counterpart.
As a single transceiver with these two modes of operation, the Cisco dual-rate BiDi enables data center operators to re-use their existing duplex LC-connectorized MMF infrastructure for migration from 10 Gb to either 40 Gb or 100 Gb Ethernet connectivity, or migration from 40Gb to 100Gb.
Features
40Gb and 100Gb dual-rate capability
Backward compatibility with 40Gb QSFP+ BiDi
QSFP28 form factor
Operates over duplex LC-connectorized MMF fiber infrastructure, same as 10Gb SR and 40Gb BiDi
Onboard forward error correction
PAM4 optical modulation
Bi-directional optical technology
Enables incremental upgrade to 100Gb from 10Gb SR or 40Gb BiDi
Backward compatible with Cisco’s 40Gb BiDi technology
Only Cisco offers backward compatibility with native 40Gb BiDi transceivers in a QSFP28 form factor. Like the native 40Gb BiDi, the dual-rate 40/100 Gb BiDi transmits bi-directionally on both fibers, using nominal wavelengths of 850nm and 910nm and passive wavelength division multiplexing (WDM) filters at either end isolate Tx and Rx channels. In 40Gb mode, it transmits and receives 20Gb NRZ channels on each fiber, for a total aggregate bandwidth of 40Gb.
In 100Gb mode, it operates 50Gb PAM4 channels, for a total aggregate bandwidth of 100Gb. PAM4 technology enables 50Gb data rate with signaling at 25Gbaud rates. he 40/100G BiDi contains a gearbox to translate the signal from a 4x25G format, native to the QSFP28 form factor, to the 2x50Gb format for the optical domain. It also employs onboard forward-error-correction (FEC) to reduce bit error rate. This makes it possible to use current generation transmitter and receiver technology.
The dual-rate 40/100 Gb BiDi offers multiple migration options to Cisco customers who are currently operating either 10Gb or 40Gb links in their data center architectures. By upgrading network equipment one end at a time, operators can exercise flexibility in schedules and budgets.
