Extreme Networks Compatible 50GBASE-ZR2 QSFP28 is a high performance transceiver that supports up to 80km link lengths over OS2 SMF. Digital Diagnostics functions are available via a 2-wire serial interface. The two transmitters are cooled 1310nm LAN-WDM lasers generating two optical 25Gbps output signals, which are multiplexed together at the optical output port. The two receivers are PIN Photodiodes which detect (after optical de-multiplexing) 2× 25Gbps optical input signals.
This transceiver is compliant with QSFP28 MSA, SFF-8661, SFF-8679 and SFF-8636 standards. It is suitable for 50GBase Ethernet applications.
