Cisco Optics
Cisco offers a wide variety of pluggable transceiver modules across Cisco
switches and router platforms Cisco pluggable transceivers provide a convenient and
cost-effective solution for the adoption of Fast Ethernet, Gigabit Ethernet, and 10 Gigabit
Ethernet in data center, campus, metro access, and storage area networks
Cisco 10 Gigabit Modules
Cisco offers a range of XENPAK, X2,
and XFP modules for 10 Gigabit
Ethernet (10GbE) deployments. These
Cisco transceivers meet Cisco
specifications and are compliant with
industry standards. Cisco XENPAK,
X2, and XFP offer a convenient and
cost-effective solution for the adoption
of 10GbE in data center, campus,
metropolitan area access, and ring
networks. XENPAKs are offered for
several reaches and transmission
media and are supported on the
Catalyst 6500, 3750 Series switches,
and Cisco 7600 and CRS-1 routers today.
X2s are also offered for several
reaches and transmission media and
are supported on the Catalyst 4500,
4948-10GE, 3750-E and 3560-E Series
switches today. The Cisco XFP Module
offers customers a dual rate interface
for 10GbE and Packet-over-SONET/
SDH (POS) connectivity. XFPs are
currently supported on Cisco routers
based on Shared Port Adapter (SPA).
Cisco CWDM Modules
Cisco Course Wave Division
Multiplexing (CWDM) Solution allows
scalable and easy-to-deploy Gigabit
Ethernet (GbE) and Fibre Channel
services. The combination of CWDM
GBICs and CWDM SFPs and CWDM
Optical Add-Drop Modules (OADMs)
and Multiplexers enables the design
of a flexible and highly available
multiservice network.
The Cisco CWDM Solution offers a
convenient and cost-effective solution
for the adoption of optical Gigabit
Ethernet in campus, data center, and
metropolitan-area access networks.
Cisco CWDM Solution consists of a
set of eight different Cisco CWDM
GBICs (one for each of the eight
different colors or wavelengths), eight
different SFPs, a set of eight single
wavelength/dual channel OADMs, two
four-channel OADM/MUX and an eight-
channel MUX along with a CWDM
rack-mountable chassis.
Cisco DWDM Transceiver
Modules
The Cisco Dense Wave Division
Multiplexing (DWDM) XENPAKs allow
users to integrate WDM transport
directly with Cisco 10GbE switches
and routers. The DWDM XENPAKs
and DWDM optical filter and amplifier
products (Cisco ONS15216 series)
enable the design of a flexible and
highly available multiservice network.
The DWDM XENPAKs support 100GHZ
ITU grid and match the 4-skip-1
channel plan of Cisco ONS 100GHZ
products. The DWDM XENPAKs can
be used for unamplified and amplified
designs to transmit up to 320 Gigabits
over the same pair of SMF.
The Cisco Dense Wave Division
Multiplexing (DWDM) GBICs allow
users to integrate WDM transport
directly with Cisco Gigabit Ethernet
switches and routers. Just like
DWDM XENPAK, the DWDM GBICs
interoperate with the same ONS
equipment. They can be used for
unamplified and amplified designs
to transmit up to 32 Gigabits over the
same pair of SMF.
Cisco Gigabit Ethernet SFP
Modules
Cisco offers a range of GBIC
transceivers and Small Form-factor
Pluggable (SFP) transceivers for
Gigabit Ethernet and Fibre Channel
applications. These small, modular
optical interface transceivers offer a
convenient and cost-effective solution
for the adoption of Gigabit Ethernet
and Fibre Channel in data center,
campus, metropolitan area access
and ring networks, and storage
area networks.

General Overview
Cisco Fast Ethernet SFP
Modules
Cisco offers a range of Fast Ethernet
SFP Interface Transceivers. The product
portfolio includes 100BASE-FX 100BASE-
LX, and 100BASE-BX SFPs.
• 100BASE-FX: SFP operates on
ordinary multimode fiber optic link
spans of up to 2 km in length.
• 100BASE-LX: SFP operates on
ordinary single-mode fiber optic link
spans of up to 10 km in length.
• 100BASE-BX: SFP operates on
ordinary single-mode SINGLE
STRAND fiber optic link spans of up to
10 km in length. A 100BASE-BX-D and
a 100BASE-BX-U SFP is needed for
the single strand deployment.
Cisco offers four types of 100M SFP:
