Cisco GLC-T Copper SFP Manufacturer
SFP (small form factor pluggable) is designed to convert serial electric signals into serial optical signals. SFP module is commonly inserted on a network switch so that you can connect a fiber optic system with an Ethernet system. The most popular applications where SFP modules are used include Fibre Channel and Gigabit Ethernet. Industry specifications for the SFP transceiver have been standardized by an agreement which is called the MSA (Multi Source Agreement) between competing manufacturers. The MSA guarantees inter-compatibility between vendor products. And today we'll discuss copper SFP modules.
As the growth of the network, it will be essential to maintain both configuration flexibility and high port utilization for equipment deployed at the intersection of legacy copper and newly installed optical networks. Copper small form factor pluggable (SFP) module ensures the SFP form factor has emerged as the right way to optimize port-level flexibility. The maturation of copper SFP module is playing a critical role in enabling system designers to meet these objectives while simplifying their inventory and reducing operating costs.
SFP transceivers can be acquired with a selection of receiver and transmitter types. Users can select the appropriate SFP transceiver for each fiber optic link they're deploying to supply the specified reach according to the kind of optical fiber they're using (i.e Multi Mode or Single Mode Fiber). Copper SFP transceiver is the small form pluggable transceiver modules which use a copper line for linking, and contains transmit and receive two decision points. Radiating portion consists of laser circuit and optical maser, receiving part consists of PIN, TIA and Limtiting Amp. Completion of the digital signal transparent O / E, the E / O conversion functions. Copper transceiver can be subdivided into copper SFP modules and copper GBIC modules.
Cisco offers various kinds of SFP transceiver modules that are suitable for many different Ethernet networking applications. 1000BASE-T SFP is designed on the SFP Multi Source Agreement (MSA). It is compliant with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE STD 802.3 and 802.3ab.
Cisco 1000BASE-T SFP for copper networks, such as the GLC-T and SFP-GE-T, operates on standard Category 5 unshielded twisted pair copper cabling of up to 100m (328 ft) link length. Cisco 1000BASE-T SFP modules support 10/100/1000 auto negotiation and Auto MDI/MDIX.
Cisco GLC-T 1000base-T SFP provide 1Gbps bandwidth and it provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over existing copper network infrastructure. The GLC T SFP Transceiver offers a standard serial ID information compliant with the SFP MSA. That could be accessed with the address of A0h via the 2wire serial CMOS EEPROM protocol.
In China, there are numerous SFP transceiver manufacturers, and Fibersore is the largest, which provides Cisco copper transceivers with high performance and competitive price. Fiberstore Also provides various kinds of SFP transceivers including 100M & 1G SFP, SONET/SDH SFP, 4G SFP, CWDM & DWDM SFP, BIDI SFP and Copper & SGMII SFP. SFP with special parameters can be also customized up to customers' requirements.
