Cisco SFP
can also be hot plugable, this ensure it is easy to change and
straightforward for maintenance in comparison with traditional modules.
SFP fiber transceiver modules make the fiber optic network or
fiber-Ethernet network simpler to upgrade or maintain, users can replace
a single SFP module in the process instead of switch the whole board
with lots of modules about it.
SFP(Small form-factor pluggable) is really a compact optical transceiver
found in optical communications both for telecommunication and
knowledge communications applications. Cisco Transceiver Modules support
Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco
switching and routing platforms. Cisco pluggable transceivers give you a
convenient and value effective solution for the adoption in data
center, campus, metropolitan area access and ring networks, and utility
area networks. Cisco portfolio of hot pluggable interfaces supplies a
rich set of choices with regards to speeds, protocols, reaches and
supported transmission media.
Cisco SFP can be regarded as the upgrade version gbic module,
SFP is short for Small Form-factor Pluggables, unlike GBIC with SC
fiber optic interfaces is by using LC interface and also the main body
size of SFP is only about 50 % of GBIC, helping to make SFP
space-saving. Signal transmitting rate of such modules vary from 100Mbps
as much as 4Gbps or maybe more, working distance of these SFP
transceiver modules may be from 500 meters to 100 kilo meters, working
wavelength of numerous SFP modules are usually 850nm, 1310nm and 1550nm,
there's also CWDM type SFP transceivers available.
Laser Safety:
Before you decide to install SFP modules in a Cisco device or make an
effort to operate or service a Cisco device designed with SFP modules,
you must read and take notice of the important safety information in
this article. Make reference to the Regulatory Compliance and Safety
Information publication or perhaps the Site Preparation and Safety Guide
that supports your Cisco device for the complete set of translated
safety warnings and agency approvals that connect with your Cisco
device.
The Cisco SFP Transceiver Modules have a category 1 Laser, which emits
invisible radiation. Usually do not stare into open optical ports. These
warnings connect with the cisco sfp modules.
Warning:
1,Class 1 laser product. 2,Because invisible laser radiation may be
emitted from the aperture from the port when no fiber is connected,
avoid exposure to laser radiation , nor stare into open apertures.
3,Laser radiation occurs when the system is open and interlocks
bypassed. 4,Only trained and qualified personnel ought to be able to
install, replace, or service this equipment.
