1G / 2.5G Fiber Optic Transceivers

Our 1G and 2.5G transceiver line covers the broadest range of legacy and modern access applications, with form factors including SFP, SFF, SFF 2x5, 1x9, 1x9 BiDi, 2x9, and GBIC. These modules support data rates from 155 Mbps (OC-3/STM-1) to 2.5 Gbps (2.5GbE, OC-48/STM-16, CPRI Option 1–3).

What is an SFP transceiver? The Small Form-factor Pluggable (SFP) is the industry-standard hot-swappable module used in Ethernet switches, routers, and access devices. SFP transceivers support speeds from 100 Mbps to 1 Gbps depending on the variant. Are SFP transceivers compatible with Cisco, Juniper, and Arista? Yes — all Coretek Opto SFP modules are MSA-compliant and coded for compatibility with platforms from Cisco, Juniper, Arista, Dell, Huawei, Nokia, Calix, ZTE, and other major vendors.

Reach options span the full access and metro range: multimode SX (up to 550 m on OM2), single-mode LX (10 km), EX (40 km), ZX (80 km), and ultra-long-haul (120 km). Wavelength options include 850 nm, 1310 nm, 1490 nm, 1550 nm, and BIDI WDM variants for single-fiber runs.

These transceivers are widely deployed in enterprise access/distribution layers, telecom SONET/SDH rings, broadband PON backhauling, video surveillance, industrial automation, and legacy OC-3/OC-12 infrastructure. Both commercial (0°C to 70°C) and industrial-grade (−40°C to 85°C) temperature ranges are available across most SKUs.
