The 6-port density is impressive for an OC3 card. Single-mode performance is consistent and the POS mapping is flawless.
Reliable optical links for our metro network. The intermediate reach optics are perfect for our span distances. Very stable hardware.
High uptime and professional-grade throughput. It integrates perfectly into our SONET infrastructure without any configuration hurdles.
Excellent port density and signal quality. We've seen a significant improvement in our link stability since installing this card.
Top-tier optical performance. The card is robust and handles peak data loads with ease. A solid investment for our core.
The ESR-6OC3/P-SMI is a single-mode Packet-Over-SONET/SDH line card with six OC3/STS3c/STM1c ports designed for high-performance WAN aggregation.
It supports six independent OC3 (155 Mbps)/STS3c/STM1c interfaces over single-mode fiber for reliable POS connectivity.
Yes, the ESR-6OC3/P-SMI is optimized for single-mode fiber, enabling long-reach SONET/SDH links up to 40 km.
This line card is compatible with ESR-series and major OEM carrier-grade chassis that support POS line card slots.
Power down the chassis, insert the card into an available POS slot, secure the bracket, then power up and verify link LEDs.
It supports POS framing, SONET/SDH overhead management, BERT, Loopback, and SNMP-based performance monitoring.
With single-mode optics, it achieves up to 40 km standard reach; extended-reach optics can exceed 80 km.
Yes, the card supports hot-swapping for zero-downtime maintenance and quick field replacements.
Typical power draw is 12 W per card, with a maximum of 15 W under full load conditions.
Operating temperature: 0 °C to 50 °C; relative humidity: 5 % to 95 % non-condensing; IEC-compliant.
Use the chassis’ management interface or SNMP/CLI to view port status, performance counters, alarms, and loopback tests.
