155M 1.25G PIN-TIA Photodiode

 

 

      Belycomm, a 10+ year original manufacturer based in Fujian, China, presents the 155M 1.25G PIN-TIA Photodiode (Model: ROSA-1.25G-SC-B-I) - a high-performance coaxial PD photodiode device tailored for CATV fiber optic transmission systems. As a trusted ROSA-1.25G-SC-B-I bulk supplier, we design this product to meet B2B procurement demands for reliability, consistency, and cost-effectiveness.

 

      This universal mounting type photodiode adopts advanced InGaAs PIN-PD as the receiver and laser welding technology, delivering core advantages that solve key pain points for CATV system integrators and distributors:

 

• High responsivity (≥0.88A/W @ 1550nm, Vr=5V): Minimizes signal loss, reducing overall power consumption of your CATV network.

• Low dark current (≤1nA @ Vr=5V) & low capacitance (≤0.75pF @ Vr=5V, f=1MHz): Ensures stable signal conversion even in low-light environments, avoiding data transmission errors.

• High reliability & long operation life: Laser welding technique enhances structural durability, matching the 5-10 year service cycle of CATV infrastructure.

 

     Whether you need standard units for immediate project use or custom ODM service (e.g., modified interface, package size), our professional R&D team (with 2004-founded industry experience) can tailor solutions to your B2B requirements.

As a professional optical device manufacturer, we optimize procurement terms to fit different B2B scenarios (sample testing, small-batch trial, mass production):

 

• Sample MOQ: 10 pieces (for performance testing).

• Small-batch MOQ: 100 pieces (includes 5% wholesale discount to reduce your trial cost).

• Bulk MOQ: 1000+ pieces (custom bulk pricing negotiable, with additional 3-8% discount based on order volume).

 

• 1-100 Pieces: 10-14 Working Days
• 101-1000 Pieces: 20-26 Working Days
• ＞1000 Pieces: To be negotiated (supports urgent delivery for qualified long-term partners)

 

     Tip: For project-based orders, confirm lead time 4-6 weeks in advance to align with your construction schedule - our sales team provides real-time production updates.

 

• Single Package Specifications: 20×14×5 cm (flexible packaging, anti-static & shockproof, suitable for international shipping).

• Single Gross Weight: 0.050 KG (optimized for container loading, reducing logistics costs for bulk orders).
