The S-Class Cisco 40GBASE-SR4 QSFP module supports link lengths of 100 and 150 meters, respectively, on
laser-optimized OM3 and OM4 multimode fibers. QSFP-40G-SR4-S is aligned to IEEE 40GBASE-SR4 optical
specifications which support high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP
multifiber female connectors. Because IEEE 40GBASE-SR4 does not support 4x10G breakout connectivity to
10GBASE-SR, see QSFP-40G-SR4 or QSFP-40G-CSR4 for such applications. QSFP-40G-SR4-S does not
support FCoE.
Cisco QSFP-40G-LR4-S (S-Class)
The Cisco 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometer over a standard pair of G.652
single-mode fiber with duplex LC connectors. The QSFP-40G-LR4-S module supports 40GBASE Ethernet rate
only. The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four
wavelengths are managed in the device. QSFP-40G-LR4-S does not support FCoE.
Cisco QSFP 40G BiDi
The Cisco QSFP 40-Gbps BiDirectional (BiDi) transceiver (Figure 1) is a pluggable optical transceiver with a
duplex LC connector interface for short-reach data communication and interconnect applications using MultiMode
Fiber (MMF). The Cisco QSFP 40-Gbps BiDi transceiver offers customers a compelling solution that enables reuse
of their existing 10 gigabit duplex MMF infrastructure for migration to 40 Gigabit Ethernet connectivity.
The Cisco QSFP 40-Gbps BiDi transceiver supports link lengths of 100 and 150 meters on laser-optimized OM3
and OM4 multimode fibers, respectively.
The Cisco BiDi transceiver complies with the QSFP MSA specification, enabling customers to use it on all QSFP
40-Gbps platforms to achieve high-density 40 Gigabit Ethernet networks.
Each Cisco QSFP 40-Gbps BiDi transceiver consists of two 20-Gbps transmit and receive channels in the 832-918
nanometer wavelength range, enabling an aggregated 40-Gbps link over a two-strand multimode fiber connection.

Cisco QSFP-40G-BD-RX
The Cisco QSFP 40-Gbps BiDi monitor is a pluggable optical module for use with link monitor hardware, such as
the Cisco Nexus® Data Broker. Like the QSFP BiDi transceiver, it has a duplex MMF LC connector interface. The
QSFP BiDi monitor is used only in the monitoring path of a link containing a passive optical tap splitter. The Cisco
QSFP monitor offers the same specifications as the QSFP BiDi Transceiver, except that it does not transmit any
signal, and thus eliminates the risk of interfering with the live BiDi link path.
Cisco QSFP-40G-SR4
The Cisco 40GBASE-SR4 QSFP Modules support link lengths of 100 meters and 150 meters, respectively, on
laser-optimized OM3 and OM4 multimode fibers. It primarily enables high-bandwidth 40G optical links over 12-fiber
parallel fiber terminated with MPO/MTP multifiber female connectors. It can also be used in a 4x10G breakout
mode for interoperability with 10GBASE-SR interfaces up to 100 and 150 meters on OM3 and OM4 fibers,
respectively. The worry-free 4x10G mode operation is enabled by the optimization of the transmit and receive
optical characteristics of the Cisco QSFP-40G-SR4 to prevent receiver overload or unnecessary triggering of alarm
thresholds on the 10GBASE-SR receiver, and at the same time is completely interoperable with all standard
40GBASE-SR4 interfaces.
The 4x10G connectivity is achieved using an external 12-fiber parallel to 2-fiber duplex breakout cable, which
connects the 40GBASE-SR4 module to four 10GBASE-SR optical interfaces. Cisco QSFP-40G-SR4 is optimized
to guarantee interoperability with any IEEE 40GBASE-SR4 and 10GBASE-SR (in 4x10G mode).
Cisco FET-40G
Cisco FET-40G QSFP Modules are fabric-extender transceiver modules used to connect to fabric links (links
between the fabric extender switch and the parent switch). The interconnect works over parallel multimode fiber
across distances of up to 100 and 150 meters, respectively, on laser-optimized OM3 and OM4 multimode fiber
cables. This module can be used for native 40G optical links over 12-fiber ribbon cables with MPO/MTP connectors
or in 4x10G mode with parallel-to-duplex fiber breakout cables for connectivity to four FET-10G interfaces.
Cisco QSFP-40G-CSR4
Cisco 40GBASE-CSR4 QSFP Modules extend the reach of the IEEE 40GBASE-SR4 interface to 300 and 400
meters on laser-optimized OM3 and OM4 multimode parallel fiber, respectively. Each 10-gigabit lane of this
module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links
over 12-fiber parallel cables with MPO/MTP female connectors or in a 4x10G breakout mode with parallel to duplex
fiber breakout cables for connectivity to four 10GBASE-SR interfaces. Cisco QSFP-40G-CSR4 is optimized to
guarantee interoperability over the complete specification range of 10GBASE-SR.
Cisco QSFP-40G-LR4
The Cisco 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometers over a standard pair of G.652
single-mode fiber with duplex LC connectors. The 40 Gigabit Ethernet signal is carried over four wavelengths.

interoperable with 40GBASE-LR4 for distances up to 2 kilometers. The operating temperature range is from +10 to
+60°C with an optical link budget of 4 decibels. This 4-decibel link budget offers the ability to support the loss from
patch panels in the link in a data center environment.
Cisco QSFP-4X10G-LR-S (S-Class)
The Cisco QSFP-4X10G-LR-S QSFP module supports link lengths of up to 10km on G.652 Single-Mode Fiber
(SMF). It enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP multifiber
female connectors. It can also be used in a 4x10G mode for interoperability with 10GBASE-LR interfaces up to
10km.
The 4x10G connectivity is achieved using an external 12-fiber parallel to 2-fiber duplex breakout cable, which
connects the 4x10G LR module to four 10GBASE-LR optical interfaces. Cisco’s QSFP-4X10G-LR-S is optimized to
guarantee interoperability over the full specification range of 10GBASE-LR in 4x10G mode. QSFP-4X10G-LR-S
does not support FCoE.
Cisco QSFP-40G-ER4
The Cisco 40GBASE-ER4 QSFP Module supports link lengths up to 40km over G.652 single-mode fiber with
duplex LC connectors. The 40GE or OTU3 signal is carried over four wavelengths in the 1310nm range.

Cisco QSFP-40G to SFP-10G Adapter Module
The Cisco QSFP to SFP or SFP+ Adapter (QSA) Module offers 10 Gigabit Ethernet and 1 Gigabit Ethernet
connectivity for QSFP 40G-only platforms. It allows smooth and cost-effective migration to 40 Gigabit Ethernet by
providing an option to use lower-speed SFP or Enhanced Small Form-Factor Pluggable (SFP+) modules in empty
QSFP ports or when the other end of the network is running at lower speeds.
The Cisco QSA Module (Figure 6 and Figure 7) converts a QSFP port to an SFP or SFP+ port. With this adapter,
customers have the flexibility to use any SFP+ or SFP module, or cable to connect to a lower-speed port on the
other end of the network. This flexibility allows a cost-effective transition to 40 Gigabit Ethernet by maximizing the
use of high-density 40 Gigabit Ethernet QSFP platforms. This adapter supports all SFP+ optics and cable reaches
and several 1 Gigabit Ethernet SFP modules (see Table 2 that follows).

QSFP-40G-SR-BD has 0.7 decibel incremental margin (in addition to 1.9 decibel total loss budget shown in Table 4), which can
be allocated to connector losses in the link for OM3 fiber for applications when a link BER of 1E-12 is sufficient. Cisco
recommends that this margin be allocated to connector losses. Care should be taken to not exceed 120 meters in fiber link
distance with the OM3 fiber.
