Bulgarian manufacturers like Cimler Ltd. and Fibicon provide high-quality fiber optic cables, while OSFP Active Optical Cables (AOCs) support ultra-high-speed data transmission up to 1.6T per cable.

Bulgarian Fiber Optic Cable Manufacturers

• Cimler Ltd. is a Bulgaria-based company producing a wide range of fiber optic cables for telecom, industrial, and broadband applications. Their offerings include indoor/outdoor, armored, flat drop, and flexible cables designed for high performance and durability, with a focus on reliability and international standards compliance (Cimler Ltd.), .
• Fibicon specializes in fiber optic products for FTTH, data centers, and military applications, ensuring high-quality manufacturing and testing processes (Ensun.io), .
• Opticom Ltd. provides optical communication systems, consulting, splicing, testing, and repair services, representing major international brands in Bulgaria (Opticom Ltd.), . These companies can supply the fiber infrastructure needed for high-speed OSFP AOCs, either as raw fiber or integrated cable assemblies.

OSFP Active Optical Cable (AOC) Overview

• OSFP (Octal Small Form Factor Pluggable) AOCs are designed for high-speed interconnects in data centers and telecom networks. They support 25G/lane NRZ up to 224G/lane PAM4, delivering aggregate bandwidths of 200G, 400G, 800G, and 1.6T per cable assembly (Amphenol), .
• Active variants include integrated electronics for signal amplification and equalization, enabling longer reach and higher performance compared to passive cables.
• COMNEN 800G OSFP AOCs feature 8 duplex channels with 850Gbit/s aggregate bandwidth, PAM4 modulation at 53.125G baud, and distances up to 60m on OM3 fiber or 100m on OM4 fiber. They support application selection via programmable AppSel values and comply with FCC Class B limits (COMNEN), .

Applications

OSFP AOCs are ideal for:

• High-speed data center interconnects
• Telecom backbone networks
• High-performance computing clusters
• Environments requiring low-latency, high-bandwidth connections

Summary

While Bulgaria hosts several capable fiber optic cable manufacturers like Cimler Ltd., Fibicon, and Opticom Ltd., OSFP AOCs are typically sourced from specialized global suppliers such as Amphenol and COMNEN. Bulgarian companies can provide the fiber infrastructure and integration support necessary for deploying OSFP AOCs in local data centers and telecom networks, ensuring compliance with international standards and high-performance requirements.
