Import 1310nm Dfb Coaxial Lase Diode — Buy in Bulk from Supplier in China

This 1310nm DFB coaxial laser diode is a semiconductor device designed for fibre-optic signal transmission, operating at a centre wavelength of 1310 nanometres. The DFB (Distributed Feedback) structure provides single-longitudinal-mode operation, which is critical for minimising chromatic dispersion in standard single-mode fibre. Its coaxial package, typically featuring a hermetically sealed housing with a pigtail or receptacle output, is a common form factor for integration into telecommunication transceivers and CATV optical transmitters.

The device is built around an InGaAsP/InP material system, which is standard for 1310nm laser production, offering good temperature stability and efficiency. Key performance parameters include a typical threshold current in the range of 10-20 mA and a slope efficiency that determines its optical output power per unit of drive current. The coaxial package often includes an internal photodiode for back-facet monitoring, enabling stable output power control via an external feedback circuit. These diodes are generally specified for operation within a 0 to 70 degrees Celsius temperature range.

Telecommunications equipment manufacturers and CATV network operators source these diodes for use in optical line terminals (OLT), optical network units (ONU), and analogue or digital fibre-optic transmitters. Buyers typically evaluate parameters like output power, spectral width, and side-mode suppression ratio against their system requirements. For procurement, it is essential to confirm the exact package dimensions, pinout configuration, and compliance with relevant safety standards like IEC 60825 with the supplier, as these details are not specified in the listing.
