Links that leave the building — inter-facility ties and metro spans measured in tens of kilometers — are the territory of the QSFP-100G-ERL4, which drives 100G across single-mode fiber to 40km from a standard QSFP28 cage. Coded to Arista platform expectations, it is recognized on insertion, terminates in duplex LC, and reports through DDM/DOM so optical health stays in view for the length of the run. Each serial is exercised for identification and diagnostics before it goes out the door.
