|Your personal background.
| Cisco, as we know, one of the top 500 companies in the world, mainly supplies network and communications products and service.
Its SFP transceiver is widely used with their routers and switches.
Cisco SFP is an upgraded version fiber optic transceiver from the traditional one,
which is smaller and more flexibility. Cisco SFPs include a wide range of the transceivers due to different working wavelengths and distances.
Now I will introduce you something about
the Cisco 1000Base SFP transceivers, such as GLC-SX-MM, GLC-LH-SM and GLC-ZX-SM.
Cisco GLC-SX-MM is compliant to 1000Base SX standard for Gigabit Ethernet, used for
short wavelength applications.
GLC-SX-MM works with 850nm multimode fiber, its max working distance is about 1640 feet and typical data rate is 1Gbps.
It uses LC duplex fiber optic connector interface. The GLC-SX-MM transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance
preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.
The GLC SX MM transceivers are compatible with SFP Multi-Source Agreement (MSA)
and SFF-8472. Cisco GLC-LH-SM SFP is compliant to 1000Base-LX/LH standard for
Gigabit Ethernet, used for long wavelength and long haul applications.
The GLC-LH-SM transceiver consists of three sections: a FP
laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit.
All modules satisfy class I laser safety requirements. It fully complies with the Multi-sourcing agreement (MSA) which enables it to work in all MSA compliant platforms.

into four electrical signals, and performs clock recovery, amplification, equalization, and PAM4 demodulation on the four electrical signals
by the DSP processor 108, and converts into 16 channels.
25G NRZ electrical signal is output. When receiving the optical
signal, the received 400-channel high-speed optical signal is converted into 8 25G optical signals (4-level optical
signals) through the demultiplexer (DEMUX) 206, and passes through 8 25G optical receivers (PIN/TIA).
207 converts the received optical signal into eight electrical signals,
and performs clock recovery, amplification, equalization, and PAM4 demodulation on the
eight electrical signals by the DSP processor 208, and converts them into 16 25G NRZ electrical signals.
307 converts the received optical signal into four electrical
signals, and then performs clock recovery,
amplification, equalization, and PAM4 demodulation on the four electrical signals by the DSP processor 308, and converts
into eight 50G NRZ electrical signals. Although the descriptions in FIGS.

be able to understand that the above-described integrated/external mode and single channel/multichannel
arrangement are equally applicable to the present invention. The specific embodiments described herein are
merely illustrative of the spirit of the invention. A person skilled in the art can make various modifications or
additions to the specific embodiments described or in a
similar manner, without departing from the spirit of the invention or
as defined by the appended claims.

The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications.
It interfaces a network device mother board (for a switch,
router, media converter or similar device) to a fiber optic or copper networking cable.
It is a popular industry format jointly developed and supported by many network component
vendors. 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);
the SFP is sometimes, erroneously, referred to as a 'Mini-GBIC' (although no such device has ever been defined in the MSAs).
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 requiredoptical reach over the available optical
fiber type (e.g. multi-mode fiber or single-mode
fiber). 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. Divided by rate: 155M/622M/1.25G/2.125G/4.25G/8G/10G,155M and
1.25G market is used more, 10G technology is maturing, demand is to increase quickly.
Divided according to the wavelength:
850 nm/1310 nm/1550 nm/1490 nm/1530 nm/1610 nm. The 850nm wavelength is SFP multimode , and the transmission distance is 2
km below .
1310/1550 nm is SFP single-mode , and the transmission distance is longer than 2 km.
850 nm/1310 nm/1550 nm price relatively cheaper than the other three.
Purple is the 1490 nm module and so on. SFP, with its small and
low-cost advantages to meet
the equipment needs of high-density optical modules
has become mainstream. SFP, in that it supports data rates up to 10 Gbit/s.
8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard
OTU2. It is a popular industry format supported by many network component
vendors. The small form-factor pluggable (SFP Fiber Optic Transceiver) supports data rates up to
10 Gbit/s. The SFP Fiber Optic Transceiver are available with a variety of transmitter and receiver
types. 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2.
It is a popular industry format supported by many network
component vendors. Consideration has to be given to whether the module is linear or limiting.
10GBASE-LRM otherwise limiting modules are preferred.
SFP sockets are found in Ethernet switches and network interface cards.
The SFP transceiver is specified by a multi-source agreement (MSA) between competing manufacturers.
The SFP was designed after the GBICinterface, and allows greater port density (number of transceivers per cm along the edge
of a mother board) than the GBIC, which is why SFP is also known as
mini-GBIC. The related Small Form Factor transceiver is similar in size to the SFP, but is soldered to the host board as apin through-hole device, rather than plugged into an edge-card socket.
However, as a practical matter, some networking
equipment manufacturers engage in vendor lock-in practices whereby they deliberately
break compatibility with "generic" SFPs by adding a check in the device's firmware that will
only enable the vendor's own modules. The SFP transceiver contains a PCB
that mates with the SFP electrical connector in the host system.
MOD-DEF 0,1,2 are the mode definition pins. Side
view of SFP module (length is 6 cm). The physical dimensions of the SFP transceiver are slightly smaller than the later XFP transceiver.
The SFP MSA defines a 256-byte memory map in EEPROM describing
the transceiver's capabilities, standard interfaces,
manufacturer, and other information, which is accessible
over IÂ²C interface at the 8-bit address 1010000X (A0h).
Modern optical SFP transceivers support digital diagnostics monitoring (DDM) functions according to the
industry-standard SFF-8472. This feature is also known as digital optical monitoring (DOM).
This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical
input power, temperature, laser bias current, and transceiver supply voltage.
The diagnostic monitoring controller is available as IÂ²C device at address 1010001X (A2h).
