DWDM SFP Transceiver From FiberStore

Dense Wavelength Division Multiplexing (DWDM) Small Form-Factor Pluggable (SFP) transceivers provide the high speeds DWDM SFP transceiver and physical compactness that today’s networks require while delivering the deployment flexibility and inventory control that network administrators demand. Usually DWDM SFP modules applied in SDH/SONET. DWDM SFP modules provided by FiberStore are available in all 100 GHz or 50GHz C-band wavelengths on the DWDM ITU grid.

For SFP Module at fiberstore.com, you can choose one from more than 500 items, you can narrow by from Compatible SFP(such as Cisco SFP, HP SFP, Juniper SFP, Dell SFP, Netgear SFP, Extreme SFP, Force10 SFP, Brocade SFP, etc.), Transfer Distance(0-100m, 100m-800m, 1km-5km, 5km-20km, 20km-40km, 40km-80km, 80km-120km, above 120km), Wavelength(Multi-mode 850nm, Single Mode 1310nm, Single Mode 1550nm, BIDI 1310/1490/1550, Multi-mode 1310nm) and Fiber System(Simplex, Duplex). There always has one DWDM SFP optical module just meet your demand. There are also DWDM SFP+ transceiver available. As you know, SFP+ transceiver is an enhanced transceiver upgraded from SFP, smaller but higher performance.

DWDM SFP+ transceiver is actually created specifically with regard to service providers as well as big businesses that need the scalable, versatile, cost-effective program with regard to multiplexing, moving as well as safeguarding high-speed data, storage space, tone of voice as well as movie programs within point-to-point, add/drop, diamond ring, nylon uppers as well as celebrity system topologies. DWDM allows providers to support numerous countless aggregated providers associated with any kind of sub-rate protocol without having setting up additional dark fiber.

CWDM SFP+ transceiver enables 10G through existing CWDM filters, without the need for a hybrid DWDM design, while our DWDM SFP+ transceiver allows the use of fiber-conserving WDM solutions in standard switches and routers, eliminating the need for a separate optical transport device.

The Main Parameters of Cisco SFP Transceiver Modules

Cisco System, Inc. established in 1984, is an international reputable company providing internet solutions, equipment and software products, whose products are mainly used to connect a computer network system, Cisco routers, switches and other equipment carries 80% of global Internet communications, of the new economy in the Silicon Valley legend. Over the past 20 years, Cisco has almost become synonymous with the Internet, network applications, productivity, Cisco have become the market leader in every area of its entry. The company is also specialized in producing transceiver modules include a well advanced and useful type of transceiver namely mini GBIC or SFP module.

SFP is the abbreviation of Small Form Factor Pluggable referring to a compact small and hot-pluggable transceiver. Cisco SFP transceivers are designed to change the series electric signals to the serial optical signals for either telecommunication or data communication fields. The transceiver is usually working with a network device a switch or a router to connect to a copper networking cable or fiber optic. SFP is a recognized industry standard thus is supported by almost every leading vendors such as H3C, HP, Huawei. It is designed to support communication in standards such as Gigabit Ethernet, SONET, Fibre Channel and many others.

The main parameters of the SFP module

Average transmit optical power (TxLOP: Optical Average Power) average transmit optical power refers to the signal logic 1 when the optical power and for 0:00 the arithmetic mean of the optical power. P0 + the P1 PAVG = 2 (dBm)

Consumers light ratio (ER: ExtinctiRatio) signal logic to 1, the optical power and is 0 when the light power size ratio. The calculation formula for: P1ER = 10log P0 (dB) ER extinction ratio, the unit is dB, P1 and P0 represents the logic 1 and 0 when the optical power.

The minimum average light reception sensitivity (Receiver Sensitivity) measure the receiving end of a certain bit error rate (1 × 10exp (-12)) To ensure the desired reception power, in units of dBm. BER is within a longer period of time, after received after the receiving side of the photoelectric conversion error output terminal of the number of symbols with the BER tester gives the ratio of the number of symbols.

Loss indicative signal (LOS Assert) restore instruction (LOS Dessert) receiver output an electric signal, and the signal is lost and the potential level of the adequacy reflects the intensity of the optical signal received by the receiver, to determine by comparing the potential of the preset potentiometer light whether the signal is lost. Potential has a certain effect hysteresis comparator to achieve, usually default electrical signal corresponding to the optical power as an indication, in dBm

Eye mask margin (EMM: Eye Mask Margin) eye opening, refers to the degree of “open” in the best sampling point eye amplitude distortion-free opening of the eye diagram should be 100 [%]. Eye diagram template tolerance eye mask expansion, until the eye diagram of the sampling points into the template of the biggest expansion of the expansion area percentage.

Cisco SFP is flexible in its extensive set of items including Cisco GLC-T, Cisco GLC-SX-MM, Cisco GLC-LH-SM, Cisco CWDM SFP, which can be used with the union of 1000BASE-T, 1000BASE-SX, 1000BASE- LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U in a port-by-port basis.
