Ciena K78-0200-900 6200 Base And Expansion Chassis

The Ciena K78-0200-900 6200 Base and Expansion Chassis is a modular packet‑optical transport and network aggregation platform that combines a 7‑slot base chassis with a 5‑slot expansion chassis for scalable, carrier‑grade networks. It features an integrated air filter with forced‑air cooling for high‑density multiservice deployments and offers mounting in 19 in., 23 in., or ETSI racks. The system supports Ethernet, SONET/SDH, OTN, packet transport, and Layer 2 switching (module dependent) and is compatible with Ciena 6200 service interface modules and optical networking infrastructure. Technical details include base 7‑slot, expansion 5‑slot, dimensions 220 × 444 × 235 mm (8.7 × 17.5 × 9.2 in.), weight approximately 13 kg (28.7 lb), and power options of AC 100–240 VAC for the base chassis and DC (-40 to -72 VDC) for the expansion chassis.
