American Fibertek (AFI) — Fiber-optic modules, video/data transmitters and SFPs for security & network projects
American Fibertek (AFI) is a U.S.-based manufacturer of fiber-optic communications equipment focused on practical products for CCTV/video surveillance, Ethernet media conversion, alarm/contact telemetry and industrial network links. AFI’s range includes SFP transceivers, bi-directional single-fiber and dual-fiber modules, rack-card transmitters/receivers, standalone video/audio modules and industrial hardened media devices with PoE options.
What AFI is known for
- Field-ready video and data modules that integrate with security headends and camera systems.
- Extensive SFP portfolio covering 100 Mb to 10 Gb, with singlemode/multimode and DDM support.
- Industrial media converters and PoE-enabled units rated for extended temperatures and industrial mounting.
Main product families & technologies
- SFP / SFP+: Dual-fiber LC and single-fiber bi-di transceivers in multiple wavelengths and link budgets.
- Rack cards and module transmitters/receivers: Hot-swappable cards and modules for multi-channel video, audio and contact data.
- Media converters & industrial units: DIN-rail and hardened devices with link-loss features and PoE where required.
Common applications
- Security surveillance: long-distance camera links, audio and alarm contact transmission.
- Enterprise & campus networks: fiber uplinks and CWDM/CWDM-style wavelength options.
- Industrial/critical infrastructure: hardened units and PoE to support remote devices in harsh conditions.
How Safsale helps buyers identify AFI models
- Model cues: MT/MTX = transmitter; MR/MRX = receiver; RR/RRM = rack card; SFP/SFPP = pluggable transceivers; suffixes indicate fiber type, wavelength or connector.
- Search & filters: Category and attribute filters let buyers narrow by speed, fiber type, connector and distance.
- Images & spec blocks: Photographs and short specs on listings show physical form and connector type.
- Datasheets & PDFs: Downloadable datasheets provide optical budgets, operating temperatures, power and diagnostics for compatibility checks.
- Reviews & Q&A: Real-world feedback helps confirm interoperability with switches and camera systems.
Sourcing and replacement guidance
Always match connector type, fiber count (single-fiber bi-di vs dual-fiber), wavelength and optical budget when replacing modules. Confirm mechanical fit for rack cards versus standalone units and verify power requirements and temperature rating for industrial deployments. For SFP replacements, check vendor-compatibility notes and DDM support when required.
Safsale’s organized listings, clear photos, downloadable AFI datasheets and community Q&A speed the identification of correct replacements and reduce procurement risk for integrators, contractors, facilities teams and OEM buyers.
