Pushing the boundaries of optical networking since 2014.
OptiModule is the optical transceiver brand of eSeeSky Inc., founded in 2014 and headquartered in Markham, Ontario, Canada. What began as a regional supplier to Canadian telecoms has grown into a globally recognized manufacturer delivering high-performance optical modules to data centers, carriers, and enterprises across more than 50 countries.
Today, our portfolio spans every major speed tier — from 10G SFP+ modules for enterprise edge to cutting-edge 800G QSFP-DD transceivers for AI/ML infrastructure — all engineered to MSA standards and backed by rigorous factory validation.
Every module is engineered to comply with MSA standards and tested for full compatibility with Cisco, Arista, Juniper, Huawei, and more — without vendor lock-in.
By manufacturing and selling direct, we eliminate distributor markups — giving you enterprise-grade quality at competitive prices with volume discounts available.
Our engineering team is available around the clock — from pre-sales consultation to post-deployment troubleshooting — ensuring minimal downtime for your network.
Every module undergoes 100% optical power, BER, and temperature cycling tests before shipment. We maintain a <0.1% field failure rate across all SKUs.
We maintain large buffer stock of our most popular 10G, 100G, and 400G SKUs — enabling same-day order processing and fast global shipping via FedEx, DHL, and UPS.
All OptiModule products are manufactured under ISO 9001:2015 quality management systems and comply with RoHS and REACH environmental directives.
