Overview
Product sourcing insights & recommendations
The RTXM139 001 is a specialized 155Mbps SFP transceiver module manufactured by WTD/Accelink, primarily used for legacy SDH/SONET infrastructure and industrial networking. ArrowHigh-Tech
Key Findings
- Industrial Performance: Unlike standard modules, the "001" variant is rated for industrial temperatures (-40°C to +85°C), making it critical for outdoor or high-heat environments. Made-In-ChinaHigh-Tech
- Market Lifecycle: The product is in a "maintenance sunset" phase. Demand is driven by the need to replace failing parts in legacy STM-1/OC-3 networks and long-lifecycle industrial systems (utilities/transportation). MarketsandmarketsDatainsightsreports
- Pricing & Availability: Current B2B market prices range from $3.50 to $10.00 for bulk orders. While new units are still produced, a robust secondary market for refurbished units offers significant cost savings. AlibabaAlibabaTxo
