2 Glenair is a compact low noise PCB Mount RF-over- Fiber Transmitter that has useful RF bandwidth from 2 MHz to 3 GHz with excellent Spurious Free Dynamic Range (SFDR) performance when used in conjunction with RF-over-Fiber Receiver. The mechanical design is suited to the harsh temperature and vibration environments found in Military, Aerospace, Railway, Oil and Gas, and Industrial applications. The device is comprised of a transmitter section that resides in an enclosed, EMI shielded package that interfaces with a host board through a high speed electrical PCB Mount connector. The RF to Optical transmitter includes Low Noise RF amplifiers driving an uncooled distributed-feedback (DFB) laser module, laser bias control and compensation circuits are also included. APC fiber optic contact is standard. Other connector options are also available is the low noise configuration of the KEY FEATURES/BENEFITS Rugged PCB Mount design 2 MHz to 3 GHz Bandwidth Low Noise High Spurious Free Dynamic Range (SFDR) link in conjunction with PCB mount module is securely mounted with screws to ensure excellent shock and vibration performance Captive screws to simplify manufacturing logistics and assembly HOW TO ORDER TABLE 1 High-Speed electrical plug-in connector eliminates the need for soldering or coax cable interfaces, and enables ease of servicing -40 C to +85 C Operating Case Temperature Evaluation fixture available APPLICATIONS Harsh Environments such as: Airborne, Tactical, Railway, Industrial, Oil and Gas and Shipboard applications Part Number Fiber Pigtail Modifier Fiber Length Blank = SMF Fiber pigtail (0.5m-2m), SC/APC Blank (0.5m-2m) 2 MHz - 3 GHz, Transmitter -GHD = Glenair High Density, APC Contact ( C), SMF pigtail Example PNs: = Transmitter, SC/APC, 0.5m to 2m SMF pigtail length GHD-0185 = Transmitter, GHD APC Contacts, 18.5 SMF pigtail length Standard Tolerances for Fiber Pigtail Length Tolerance 4 to inches to -0 inches 12 to inches to -0 inches 24 to inches to -0 inches -xxxx Order in increments of 0.5 Example: 0185 = 18.5 See tolerances PAGE 2 of 7 sales@glenair.com
