AFLglobal.com | 800.235.3423 1 Optical Connectivity Couplers/Splitters & Multiplexers Dense Wave Division Multiplexing (DWDM) Card Guide Modules (CGM ® ) AFL’s DWDM CGM modules provide scalable wavelength management for new deployments and network upgrades, providing increased bandwidth over a single common fiber. Passive circuit design utilizes proven thin-film filter technology featuring low insertion loss, high isolation, and superior environmental stability. Modules can be installed in AFL’s CGM Plus chassis and are available with LC bulkheads in select configurations from 4 to 40 channels. The CGM module space efficient design allows for installation quantity of 24 modules in a single 4RU CGM Plus chassis. Applications • CATV Systems • Carrier Infrastructure • Access Networks • Small Cell Features • 50 GHz and 100 GHz ITU-T channel spacing • Low insertion loss/high isolation • Epoxy-free optical path • Express, upgrade and Tx/Rx test ports Ordering Information C01 = Single Wide CGM C02 = Double Wide CGM C03 = Triple Wide CGM C04 = Quad Wide CGM ALC0 = LC/APC Bulkhead ULC0 = LC/UPC Bulkhead Cxx 1 C F S08 C02 ALC0 S04 = Single Circuit, 4 Channels S08 = Single Circuit, 8 Channels S12 = Single Circuit, 12 Channels S16 = Single Circuit, 16 Channels S20 = Single Circuit, 20 Channels S40 = Single Circuit, 40 Channels C = Commercial A = AFL Standard Replace xx with Channel Number listed in DWDM ITU Channels table on last page of spec sheet.
