2.5Gbps 1310nm DFB LD TO-CAN (Small Ball): Your Agile OEM Partner for SDH Telecom Networks

Release time：2026-06-20

Empowering SDH Infrastructure with Responsive Manufacturing and Uncompromised Quality

In the critical realm of Synchronous Digital Hierarchy (SDH) telecommunications, the demand for stable, high-performance optical components is constant. However, equally vital is the need for a manufacturing partner who can offer both agile supply chain solutions and rapid, customized delivery. Wuhan Siyou Photoelectric Technology, a leading OEM and ODM service provider in the optical communication industry since 2014, proudly presents its 2.5Gbps 1310nm DFB LD TO-CAN (Small Ball) as the ideal solution for SDH telecom equipment manufacturers and system integrators.

The SDH Expert: Precision and Reliability at 1310nm

Our 2.5Gbps 1310nm DFB LD TO-CAN is meticulously engineered to meet the stringent requirements of SDH systems. The 1310nm DFB (Distributed Feedback) laser diode ensures an exceptionally narrow spectral linewidth and high side-mode suppression ratio, crucial for maintaining signal integrity over long distances and achieving ultra-low bit error rates (BER). This precision makes it perfect for SDH telecommunications, data communications, and other optical transmission systems, including the backbone of 5G infrastructure. Its robust performance, combined with an uncooled DFB chip, supports reliable operation from -20°C to +85°C, reducing power consumption and operational costs in harsh telecom environments.

Optimized for Integration: The Small Ball Lens Advantage

The unique TO56 package with a 2.0mm uncoated small ball lens is a testament to our commitment to efficient integration. This compact design not only ensures precise beam control but also facilitates optimal coupling efficiency into optical fibers, a critical factor for the performance of SFP/SFF optical modules commonly used in SDH applications. For OEMs, this translates into simplified module assembly, higher production yields, and ultimately, a more cost-effective solution without compromising on optical performance.
