This data sheet details the technical specifications and specialized service availability for the Cisco SG350-28SFP, a high-density managed fiber switch. All deployment, installation, and configuration services described herein are managed exclusively by SKYRS within Pakistan.
Cisco SG350-28SFP Managed Fiber Switch Overview
The Cisco SG350-28SFP is a 28-port Managed Gigabit SFP Switch designed to serve as a high-speed aggregation or distribution layer. Unlike standard copper switches, the “SFP” designation indicates that the primary ports are fiber-optic slots, making it ideal for connecting multiple buildings or remote floors over long distances with minimal electromagnetic interference.

Hardware Variants and Fiber Options at SKYRS
SKYRS provides the SG350-28SFP along with a comprehensive inventory of optical transceivers to ensure compatibility with Pakistan’s diverse fiber infrastructure:
-
SG350-28SFP (Base): The core 24-port SFP managed chassis with 4 additional uplink slots.
-
Transceiver Support: SKYRS stocks 1G SFP modules including GLC-SX-MMD (Multi-mode) and GLC-LH-SMD (Single-mode) for distances up to 10km.
-
High-Density Uplinks: Support for SFP-GE-T (Copper SFP) in any slot if a local RJ-45 connection is required.
-
Stacking Alternatives: While the SG350 is standalone, SKYRS provides configuration for high-bandwidth LAG (Link Aggregation) to simulate high-capacity backbones.
Professional Deployment and Installation at SKYRS
SKYRS offers end-to-end physical deployment services across Pakistan (Karachi, Lahore, Islamabad, etc.), ensuring that delicate fiber-optic hardware is handled with precision.
Deployment Deliverables:
-
Fiber Trunking & Management: Professional 1U rack-mount installation with specialized fiber patch managers to prevent excessive bending or signal loss.
-
Optical Link Validation: On-site testing using light source meters to ensure dB loss is within acceptable limits before switch activation.
-
Environmental Assessment: Ensuring the switch’s internal cooling is sufficient for the local climate, particularly in high-density aggregation racks.
-
Uplink Provisioning: Physical termination of high-speed backhaul links to the core data center or distribution hubs.
Configuration and Management Availability
Configuration services are performed exclusively by SKYRS certified technical staff to ensure the SG350-28SFP operates as a secure, high-speed fiber hub.
Configuration Services Include:
-
Fiber Aggregation: Setting up Link Aggregation Control Protocol (LACP) to combine multiple SFP ports for increased backbone bandwidth.
-
Advanced VLAN Architectures: Implementing Q-in-Q tunneling or standard VLAN segmentation for multi-tenant or multi-departmental security.
-
Security Hardening: Deployment of IEEE 802.1X, Access Control Lists (ACLs), and Storm Control to protect the fiber core.
-
Layer 3 Inter-VLAN Routing: Configuring the switch to handle local routing, significantly reducing the latency for internal data transfers.
-
Management Setup: Configuring secure SSH, HTTPS, and SNMPv3 for remote monitoring by the SKYRS NOC (Network Operations Center).
2026 Support and Lifecycle Status
As of April 2026, the Cisco SG350 series has transitioned into its final support phase.
SKYRS Support Update: The official Last Date of Support (LDoS) for the SG350 series is January 31, 2028. SKYRS remains the primary provider in Pakistan for local hardware replacement, technical configuration troubleshooting, and extended maintenance. For new infrastructure upgrades, we recommend evaluating the Cisco Business 350 (CBS350) series as the direct modern replacement.
