The JBX02435 25GBASE-CWDM-10 SFP28 transceiver represents a cutting-edge solution for modern high-speed networking environments. This optical module combines exceptional performance with proven compatibility, making it an ideal choice for data center upgrades, network expansions, and enterprise connectivity requirements. **Technical Specifications & Performance:** Operating at 1330nm wavelength with CWDM technology, this SFP28 transceiver delivers consistent 25 gigabit-per-second throughput over 10-kilometer distances on standard single-mode fiber infrastructure. The 9/125 micrometer singlemode fiber core design ensures optimal signal integrity and minimal modal dispersion, critical for long-distance, high-bandwidth applications. The module achieves IEEE 802.3by compliance, guaranteeing interoperability with standards-based network equipment. **Connectivity & Installation:** Duplex LC/UPC connectors provide secure, efficient fiber connections with superior return loss performance. The UPC (Ultra Physical Contact) polish specification delivers -50dB typical return loss, essential for maintaining signal quality in dense network environments. Installation is straightforward with standard SFP28 form factor compatibility. **Reliability & Compliance:** Manufactured with precision metal case housing containing advanced laser transmitter components, the transceiver operates reliably across extended temperature ranges (0°C to 70°C). The module holds Class 1 laser safety certification from FDA and TUV authorities, ensuring workplace safety compliance. Full RoHS/ELV compliance makes it suitable for environmentally conscious enterprises and regulated industries. **Juniper Ecosystem Integration:** Direct compatibility with Juniper networking platforms, specifically replacing OEM part SFP-25G-CWDM-1331, simplifies deployment in existing infrastructure. This compatibility eliminates costly integration challenges and ensures plug-and-play functionality. **Value & Support:** Every module includes a 90-day limited warranty and custom brand programming options for specialized deployment scenarios. Fast shipping from U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99 provides exceptional value. Ideal for network administrators, data center operators, and telecommunications professionals seeking reliable optical connectivity without premium pricing.
