Overview
The Cisco Compatible 50GBASE-ZR2 QSFP28 transceiver is designed for high-capacity 50Gbps Ethernet connectivity over single-mode fiber (SMF). This module utilizes a 1310nm LAN-WDM laser configuration to enable data transmission over distances up to 80km. It incorporates a dual-transmitter architecture that multiplexes two 25Gbps signals into a single optical output, supported by integrated CDR (Clock and Data Recovery) on both transmit and receive paths.
Key Features
- Supports 50Gbps data rates for 50GBASE-ZR2 Ethernet applications over distances reaching 80km.
- Equipped with built-in TX and RX Clock and Data Recovery (CDR) to ensure signal integrity across long-reach fiber runs.
- Utilizes a high-performance cooled 1310nm LAN-WDM laser array for stable transmission over single-mode fiber.
- Features digital diagnostic monitoring (DDM/DOM) via a 2-wire serial interface, allowing for real-time monitoring of transceiver parameters.
- Integrated KP4 FEC (Forward Error Correction) support to mitigate bit errors in high-speed transmission environments.
- Designed in a hot-pluggable QSFP28 form factor, allowing for maintenance and upgrades without disrupting network operations.
