Cisco Switch Controllers Accepted these SFP Modules

A distribution system port connects the controller to a neighbor switch and is used as the data path between these two devices. This paper talk about a few common methods on the models that have these options. Cisco 4402 controllers have two Gigabit Ethernet distribution system ports, each of which is capable of managing up to 48 access points (AP). Cisco 4404 controllers have four Gigabit Ethernet distribution system ports, each of which is capable of managing up to 48 APs per port. The 4404-25, 4404-50, and 4404-100 models allow a total of 25, 50, or 100 APs to join the controller. The Gigabit Ethernet ports on the 4402 and 4404 controllers accept these SX/LC/T SFP modules:

  • 1000BASE-SX SFP modules, which provide a 1000-Mbps wired connection to a network through an 850nm (SX) fibre-optic link using an LC physical connector
  • 1000BASE-LX/LH SFP modules, which provide a 1000-Mbps wired connection to a network through a 1300nm (LX/LH) fibre-optic link using an LC physical connector
  • 1000BASE-T SFP modules, which provide a 1000-Mbps wired connection to a network through a copper link using an RJ-45 physical connector

1000BASE-T SFP modules

The Cisco 5508 controllers have eight Gigabit Ethernet distribution system ports through which the controller can manage multiple APs. The 5508-12, 5508-25, 5508-50, 5508-100, and 5508-250 models allow for 12, 25, 50, 100, or 250 APs to join the controller. Cisco 5508 controllers have no restrictions on the number of APs per port. However, Cisco recommends using link aggregation (LAG) or configuring dynamic AP-Manager interfaces on each Gigabit Ethernet port to automatically balance the load. If more than 100 APs are connected to the 5500 series controller, make sure that more than one Gigabit Ethernet interface is connected to the upstream switch. The Gigabit Ethernet ports on the 5508 series controller, make sure that more than one Gigabit Ethernet interface is connected to the upstream switch. The Gigabit Ethernet ports on the 5508 controllers accept these SX/LC/T small-factor plug-in (SFP) modules:

  • 1000BASE-SX SFP modules, which provide a 1000-Mbps wired connection to a network through an 850nm (SX) fibre-optic link using an LC physical connector
  • 1000BASE-LX SFP modules, which provide a 1000-Mbps wired connection to a network through a 1300nm (LX/LH) fibre-optic link using an LC physical connector
  • 1000BASE-T SFP modules, which provide a 1000-Mbps wired connection to a network through a copper link using an RJ-45 physical connector

The Cisco Catalyst 6500 Series Gigabit Ethernet interface module is a premier modular multilayer switch and delivers secure converged services from the wiring closet to the core, to the data centre, to the WAN edge. Designed to complement the many roles that the Cisco Catalyst 6500 Series plays in a network, Cisco Catalyst 6500 Series mixed media Gigabit Ethernet modules offer the broadest selection of media, densities, performance, interoperability, and chassis deployments for enterprises and service providers. The Cisco Catalyst 6500 Series Gigabit Ethernet Interface Module accept these SX, LX/LH, ZX and CWDM/DWDM SFP modules:

  • GLC-SX-MM, 1000BASE-SX SFP (multimode only) Dual LC connector
  • GLC-ZX-SM, 1000BASE-ZX SFP (single mode only) Dual LC connector
  • GLC-LH-SM SFP, 1000BASE-LX SFP (single mode only) Dual LC connector
  • GLC-T SFP, 1000BASE-T SFP (copper twisted pair) RJ-45 connector
  • CWDM-SFP-1470=*, Cisco CWDM SFP 1470 nm; Gigabit Ethernet and 1G/2G FC
  • DWDM-GBIC-60.61***, 1000BASE-DWDM 1560.61 Nm GBIC (100 GHz ITU grid)

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 fibre 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 GLC-T copper SFP modules.

Cisco GLC-T SFP

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 GLC-T 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 fibre optic link they’re deploying to supply the specified reach according to the kind of optical fibre they’re using (i.e Multi Mode or Single Mode Fibre). GLC-T 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  module 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 glc-t 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.
