CHAPTER 1

Introducing the GLC1320G-55

1.1 GLC1320G-55 Overview

The GLC1320G-55 is a Gigabit Ethernet Line Card with 20 SFP slot connector slots for fiber-based

SFP (mini-GBIC) transceivers (16 for SFP transceiver and 4 for CSFP/SFP). It connects through

fiber-optic cables to other Ethernet switches that support fiber connections (like the FSG1100HN,

GS2200-8 or FMG3024/3025) located at the subscriber’s premises.

Figure 1 GLC1320G-55 Overview

The GLC1320G-55 supports various SFP transceivers to satisfy a wide range of loop length

requirements (see Table 3 on page 15 for details).

The GLC1320G-55 lets you easily implement high-speed optical FTTH (Fiber To The Home) or FTTB

(Fiber To The Building) networks. The GLC1320G-55’s 1000 Mbps symmetric bandwidth per-

subscriber is perfect for offering IP-based triple play (voice, video, and Internet) services

The GLC1320G-55 aggregates layer-2 traffic from Ethernet subscribers to the IES system. The

GLC1320G-55’s Ethernet QoS, security, and multicast features make it easy to deploy, provide

subscribers with differentiated classes of service, and add new services.

Refer to the directions and safety warnings in the IES User's Guide to install the line card in the IES.

See the MSC User’s Guide for detailed information on configuring the line card.
