Dell EMC Networking Transceivers And Cables
© 2019 Dell Inc. or its subsidiaries.
Dell EMC enables cost-savings through the reuse of a legacy
10GbE ber plant to support new 40GbE connections with our
40GbE duplex (multimode) ber solutions. These solutions use
wavelength multiplexing (SM4) and/or directional multiplexing
(BIDI) to transport 40GbE over a single (multimode) ber pair.
50GbE solutions
The 50GbE (consortium) specication utilizing half-populated
QSFP28 modules. In 50GbE networking environments, the
100GbE ports on our Z9100-ON, S6100-ON, S4124-ON
and S4148-ON switches can be broken out into two pairs of
2×25GbE through a QSFP28 to 2×QSFP28
†
passive copper
direct attach breakout cable (breakout DAC). (The QSFP28
†
is a
half-populated QSFP28 with 2×25GbE lanes.)
100GbE solutions
100GbE (4×25GbE) QSFP28 optical transceivers include short-
reach (SR4), intermediate-reach (CWDM4), long-reach (LR4)
and extended long-reach (ER4-lite). Standard 10GbE SFP+
and 25GbE SFP28 optics can be readily inserted, recognized,
and utilized in the 100GbE QSFP28 receptacle through the
use of a (QSA28) pluggable adapter. Although this reduces the
effective throughput of the 100GbE port to 25GbE, it provides
an immediate low-cost transceiver solution while preserving the
option for later bandwidth expansion. 100GbE QSFP28 ports
support both optical and passive copper breakout cables. Each
of the four 25 GbE lanes can be broken out into four individual
SFP28 interfaces. This solution can be deployed with a single
active optical cable (AOC) with integrated QSFP28 and SFP28
transceivers or through the use of a passive ber breakout
cable/multiplexer.Dual 100GbE solutions
To maximize front panel density, some Dell EMC switches
support QSFP28-DD (double density) modules which transport
two 100GbE data streams while consuming the same face plate
area as a single 100GbE QSFP28 module. For multimode ber
distances of 100 meters or less a pluggable transceiver module
can be used. Point-to-point DACs and AOCs will facilitate
shorter links as well as breakout applications.
Testing and warranties
Dell EMC Networking applies a rigorous process in qualifying
and maintaining all optics to guarantee a strict adherence
to IEEE standards, as well as stringent reliability testing to
guarantee a consistent and trustworthy solution. All optics
and cables released by Dell EMC Networking have passed a
comprehensive optical analytics check as well as an extensive
dynamic test suite. Dell-labeled optics are warrantied alongside
the Dell EMC switches in which they are deployed.
