Description
The Ciena 178-1021-900 is a high-performance optical transceiver module designed for use in dense wavelength-division multiplexing (DWDM) networks. Engineered for compatibility with Ciena networking platforms, this hot-swappable module supports 10Gbps data rates, making it ideal for high-capacity enterprise and service provider environments. Its compact form factor allows efficient use of space in high-density chassis configurations, while the robust build ensures reliable operation in demanding network conditions. The unit is typically used in long-haul and metro network applications where bandwidth and reliability are critical.
This transceiver module features DWDM SFP+ technology, supporting extended reach over single-mode fiber with a maximum transmission distance that can exceed 80km, depending on the optical budget and system setup. It operates on a specific ITU grid wavelength, allowing it to be deployed in multiplexed environments without interference. Key components include a high-sensitivity receiver and a precision-tuned laser transmitter, both housed in a durable metal enclosure for optimal thermal performance. Buyers seeking used network hardware will appreciate the cost-effectiveness and continued reliability of this model when sourced from reputable refurbishers.
