LPC, LPF Pigtail Style Collimators & Focusers

900 to 1700 nm; Active Area 0.004, 0.011 mm2; AA Dia. 0.075, 0.120 mm; Rise Time 0.2, 0.3 ns; Responsivity 0.75 to 0.95 A/W; Capacitance 0.65, 1.0 pF; Package TO-46, Ceramic Substrate, Connector Type FC, SC, ST OSI Optoelectronics’ FCI-InGaAs-XX-XX-XX series of high-speed, IR-sensitive InGaAs photodiodes with active area diameters of 75 and 120 µm are part of OSI Optoelectronics’s family of high-speed IR sensitive detectors with fiber pigtail package. The single mode (SM) or multi mode (MM) fiber is optically aligned to either the hermetically sealed InGaAs diode in TO-46 lens cap package enhancing the coupling efficiency and stability, or directly to the InGaAs diode mounted on a ceramic substrate. High responsivity and low capacitance make these devices ideal for very high bit rate receivers used in LAN, MAN, WAN and other high speed communication and monitoring/instrumentation systems. Angle polished connectors and custom packages are also available. For a solution involving FC connector and TO-46 attachment, users may consider either FCI-InGaAs-75-SM-FC or FCI-InGaAs-120-SM-FC in single mode operation. Similarly, the multi-mode variant is available in FCI-InGaAs-120-MM-FC using 62.5/125 µm fiber. The back-reflection of -30dB typical is to be experienced in multi mode (MM) based solutions. Key Features: High Speed High Responsivity Spectral Range 900nm to 1700nm Low Back Reflection Applications: Very High Bit Rate Receivers Used in LAN, MAN, WAN; High-speed Optical Communications; Gigabit Ethernet / Fibre Channel; SONET / SDH, ATM; Optical Power Monitoring / Instrumentation

Single Mode Patchcords; 440 to 1625 nm; Attenuation 0.5 to 20 dB; Return Loss 50, 60 dB; Power Handling ≤2 W OZ Optics’ PFA series of low cost fixed attenuating single mode fiber patchcords are ideal for high power applications and can be easily installed into fiber splice enclosures. The Attenuating Fiber Advantage: OZ Optics has recently enhanced its fixed attenuator product line by developing a new technology to precisely attenuate signals in fibers. This patent pending, fully automatable technique allows one to create fixed attenuators within any standard fiber, with low polarization dependent loss (PDL) and high power handling. The resultant attenuating fiber is physically identical in appearance and behaviour to the original fiber, allowing it to be used to build attenuating fiber patchcords. As the process used does not require the manufacture of special fiber, fixed attenuators can be constructed in small batch quantities economically. At the same time the automation aspect of the techniques allows large quantity orders to be manufactured at a reasonable cost. Attenuating fiber is capable of handling up to 2 W of optical power at 1550 nm. The attenuating section is only a couple of millimetres to a couple of centimeters long, depending on the attenuation. The fiber used in OZ attenuators features a double cladding, with an absorbing dopant in the inner cladding layer. This double cladding structure effectively suppresses light scattering into the cladding. Thus the readings will not significantly depend on the application. Attenuating patchcords are available with between 0.5 and 20 dB attenuation, in 0.1 dB increments. Higher attenuation levels and higher resolution attenuation steps are possible. Prototype and custom designs can be made quickly and in small volumes economically.
