manufactures our small form-factor pluggable (SFP) for telecommunication
and data communications applications. SFP is a compact, and hot-pluggable
transceiver which make it a good solution for integration into
products with size limitations. The SFP form factor is an electrical
interface which is specified by a multi-source agreement (MSA).
It interfaces into products such as network device motherboards
(for a switch, router, media converter or similar device). Our
SFP/SFP+ transceivers are available in both fiber optic or copper.
Xmultiple also manufacturers SFP/SFP+ networking cable.
can be used and interchanged on a wide variety of products and
can be interchanged in combinations of 1000BASE-SX, 1000BASE-LX/LH,
1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis. You
can use them for Gigabit Ethernet or Fibre Channel applications.
They provide a flexible and cost-effective solution for enterprise
networks, data centers, etc. SFP transceivers are designed to
support SONET, Gigabit Ethernet, Fibre Channel, and other communications
standards. Due to its smaller size, SFP obsoletes the formerly
ubiquitous gigabit interface converter (GBIC). In addition to
transceivers, Xmuliple manufactures a complete product line of
SFP and SFP+ cages, and connectors for all your requirements.
SFP/SFP+ transceivers are available with a variety of transmitter
and receiver types, allowing users to select the appropriate transceiver
for each link to provide the required optical reach over the available
optical fiber type (e.g. multi-mode fiber or single-mode fiber).
transceiver SFP modules are available in several different categories:
For multi-mode fiber, with black or beige extraction
lever SX - 850 nm, for a maximum of 550 m at 1.25 Gbit/s (Gigabit
Ethernet) or 150m at 4.25 Gbit/s (Fibre Channel)
For single-mode fiber, with blue extraction lever
LX - 1310 nm, for distances up to 10 km, BX - 1490 nm/1310 nm,
Single Fiber Bi-Directional Gigabit SFP Transceivers, paired as
BS-U and BS-D for Uplink and Downlink respectively, also for distances
up to 10 km. Variations of bidirectional SFPs are also manufactured
which use 1550 nm in one direction.
1550 nm 40 km (XD), 80 km (ZX), 120 km (EX or EZX), CWDM and DWDM
transceivers at various wavelengths achieving various maximum
For copper twisted pair cabling 1000BASE-T - these modules incorporate
significant interface circuitry and can only be used for Gigabit
Ethernet, as that is the interface they implement. They are not
compatible with (or rather: do not have equivalents for) Fibre
channel or SONET.
For (SFP) Fiber Optic Transceivers which support data rates up
to 10 Gbit/s, Xmultiple has multiple options available with a
variety of transmitter and receiver types.
enhanced small form-factor pluggable (SFP+) is an enhanced version
of the SFP that supports data rates up to 10 Gbit/s. The SFP+
specification was first published on May 9, 2006, and version
4.1 published on July 6, 2009. SFP+ supports 8 Gbit/s Fibre Channel,
10 Gigabit Ethernet and Optical Transport Network standard OTU2.
comparison to earlier XENPAK or XFP modules, SFP+ modules leave
more circuitry to be implemented on the host board instead of
inside the module. Consideration has to be given to whether the
module is linear or limiting. Linear SFP+ modules are most appropriate
for 10GBASE-LRM; otherwise, limiting modules are preferred.
Soluiton for all your SFP/SFP+ Requriements.
and SFP+ Transceivers are integrated into Ethernet switches and
network interface cards. Storage interface cards, also called
HBAs or Fibre Channel storage switches, also make use of SFP/SFP+
modules, supporting different speeds such as 2Gb, 4Gb, and 8Gb.
SFP and SFP+ is a low cost solutions and have the advantage of
not only low cost but offer a low profile, and ability to provide
a connection to different types of optical fiber. SFP and SFP+
also provide enhanced flexibility for networking and computer
products requiring a high speed interface..
The physical dimensions of the SFP transceiver are very low profile.
