QSFP 40G BiDi
The 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 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 QSFP 40-Gbps BiDi transceiver supports link lengths of 100 and
150 meters on laser-optimized OM3 and OM4 multimode fibers,
respectively.
The 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 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.

QSFP-40G-BD-RX
The QSFP 40-Gbps BiDi monitor is a pluggable optical module for use
with link monitor hardware, such as the 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 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.
QSFP-40G-LR4
The 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. Multiplexing and demultiplexing of the four
wavelengths are managed within the device.
