Comtech CDMER-625A Environmentally Resistant Satellite Modem

Comtech CDMER-625A Environmentally Resistant Satellite Modem

The Comtech CDMER-625A is the environmentally resistant version of the CDM-625A satellite modem, designed for controlled installations exposed to elevated levels of dust, sand and salt. Urethane conformal coating and protective interface covers provide enhanced environmental protection, while an extended operating temperature range supports operation up to 60°C. The modem also offers VersaFEC-2, ACM and optional DoubleTalk Carrier-in-Carrier for efficient, reliable satellite connectivity.
