The Cisco Coarse Wavelength-Division Multiplexing (CWDM) Small Form-Factor Pluggable (SFP) solution allows enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet in their networks. The product set helps enable the flexible design of highly available, multiservice networks.

The Cisco CWDM SFP solution is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre Channel in campus, data-center, and metropolitan-area access networks.

The Catalyst 4500 Series Dual Input AC Power Supply supports data and PoE, is designed to accept either 100V AC circuits or 200V AC circuits. The 4200W supply is the largest internal AC power supply available for the Catalyst 4500 series switch. Customer planning large scale PoE deployments can use the dual inputs in the 200V AC configuration. Customers planning for the future can deploy the 4200W power supply with a single 100V circuit.

The Cisco 6-port Voice/Fax Expansion Module provides enterprises, managed service providers and service providers the ability to directly connect public-switched telephone networks (PSTNs) and existing telephony equipment to Cisco 2821, Cisco 2851, Cisco 3825, and Cisco 3845 integrated services routers. With support for up to 24 total voice and fax sessions, the Cisco 6-port Voice/Fax Expansion Module is ideal for networks with high analog (foreign exchange office [FXO]).

The network modules provide various port densities to meet customer requirements at various price points. The optional, integrated NT1 lets customers consolidate customer premises equipment (CPE) to provide multifunction dial access server, router, and other capabilities within the Cisco routers in power-branch-office environments.

The WAN-interface-card (WIC) option offers a single ISDN BRI port (with optional NT1). The WIC-1B-S/T-V3 inserts into a mixed-media network module or is Supported on Cisco 1700, 1800, 2600, 2800, 3660, 3700 and 3800 series routers.

This product is Guaranteed 100% Compatible with the Manufacturer Original.

The Compatible Cisco 100BASE-FX Small Form-Factor Pluggable (SFP) Fast Ethernet Interface Converter is a hot-swappable device that plugs into a Gigabit Ethernet SFP port on Cisco Catalyst 3750 Series, 3560 Series, and 2970 Series switches. The Cisco SFP provides full-duplex 100-Mbps connectivity between switches over multimode fiber (MMF) infrastructures. It offers investment protection and an easy migration path for customers moving to Gigabit Ethernet connections in the future

The Cisco 8-Port Asynchronous HWIC and 16-Port Asynchronous HWIC use one (HWIC-8A) or two (HWIC-16A) high-density 8-port connectors. The 8-port asynchronous cable provides the high-density connector on one end and eight RJ-45 plugs on the other. RJ-45- to DB-25 modular adapters are used to convert the RJ-45 to a DB-25 DTE or DB-25 DCE connection.

This 3-port FXS and 4-port FXO voice and fax expansion module provides on premises FXS signaling to connect directly to a standard telephone, fax machine, or similar device and supplies ring, voltage, and dial tone. In addition, the FXO ports provide off-premises connection to the central office. FXS signaling support available includes loop-start and ground-start. There is no DID support. In addition, there is no FXO power failover support on the FXO ports.

The industry-standard Cisco Small Form-factor Pluggable (SFP) Gigabit Interface Converter is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network.

The GLC-BX-U 1000Base-BX10 SFP Module is compatible with the IEEE 802.3ah 1000BASE-BX10-U standard, operate on a single strand of standard single-mode fiber.

The GLC-BX-U SFP also support digital optical monitoring (DOM) functions according to the industry-standard SFF-8724 Multi Source Agreement (MSA). 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.

This 1-Outlet Surge Suppressor is designed to be installed between the antenna cable that is attached to an outdoor antenna and the Cisco Aironet wireless device. You can install it either indoors or outdoors. It can be connected directly to a wireless device having an external RP-TNC connector. It can also be mounted inline or as a feed-through.

Cisco Aironet 5GHz access point antennas have RP-TNC connectors and are compatible with Cisco Aironet 1200 Series and 1230AG Series access points when equipped with a RM22A radio module.

The antenna is a ruggedized high-performance colinear antenna that operates in the 5-GHz frequency range and is designed for use in large rooms or vaulted areas where extended coverage is needed. The antenna is designed to be used indoors or outdoors and can be mounted on a mast.
