GLC-T - Cisco SFP Module Overview
GLC-T - Cisco SFP Module is a genuine modular capacity expansion product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco family, the GLC-T unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is installed into a compatible chassis slot, where it works alongside the supervisor and line cards to extend the platform’s capabilities.
From a specification standpoint, it offers 1 ports for client, server or uplink connectivity. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Cisco hardware already running in the environment.
Typical deployments include short-reach data-center interconnects, campus backbone fiber links, and carrier access and metro networks. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “1000BASE-T SFP”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
Every unit at LinkNewNet is inspected and tested before dispatch, and stock is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Our warranty coverage and responsive technical support protect the purchase after it arrives, and our team can confirm revision levels and software compatibility before you order. For volume requirements we also offer configuration checks and staged delivery options.

GLC-T - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco transceiver/optic module provides physical-layer connectivity for switches and routers, converting electrical to optical signals over fiber or copper media.
Deployment guidance: When planning this GLC-T unit into a network, confirm the software image (IOS/IOS-XE/NX-OS) required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Cisco reconditioning process: Every pre-owned Cisco unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Cisco management tools.
Related models in this family: GLC-LH-SMD, GLC-SX-MMD, GLC-TE, DWDM-SFP-3112, SFP-OC48-LR2. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
Model code: T = T regulatory domain (multi-country) - this suffix indicates the feature set, power, or regulatory variant of the GLC-T, which affects software licensing and regional compliance.
