FNK-LT12x Front Load Pluggable Optical Transceiver The FNK-LT12 singlemode optical fiber transceivers provide low profile, cost effective solutions for Gigabit Ethernet and 1x Fiber Channel optical fiber data links with a duplex LC connector interface. These transceivers are fully compliant with the IEEE Gigabit Ethernet and ANSI 1x Fiber Channel standards but can be used for any other data communications purpose within their operating parameters. This transceiver consist of transmitter and receiver functions combined in a Low Profile RJ module. The optical transmitter is a high output 1310 nm FP laser. The transmitter input lines are driven with differential LVPECL signals applied to the Transmit (TX+ and TX-) pins. These signals are internally converted to a suitable modulation current by a CMOS integrated circuit. The optical transmitter can be disabled by applying an LVTTL signal to the Transmit Disable (TDIS) pin. The optical receivers consist of PIN and Preamplifier assemblies and CMOS limiting post-amplifier integrated circuits. Outputs from the receivers consist of differential CML data signals on the Receive (RX+ and RX-) pins and a single ended LVTTL loss of signal function on Loss of Signal (LOS) pin. The RX data is squelched (JAM) upon LOS Assert to prevent garbage data output when no optical signal is present Key Features & Benefits Gigabit Ethernet and 1x FC Applications, up to 10 km 3.3 V, 1310 nm, FP, Singlemode Front load pluggable miniature transceiver MSA height, but half the footprint MSA compliant Digital Diagnostics Surface Mount I/O pins for high speed signal integrity Industrial Temp Range, Vibration tolerant design Individual (separate) +3.3 V power supply per port Industry standard duplex multimode LC receptacle Full compliance to IEEE and ANSI requirements EN-60825 / IEC-825 / CDRH Class 1 Compliant 2 FNK-LT12x ORDERING INFORMATION F N K -LT12 H F = Front Load K = Gigabit Ethernet LT12 = SM N = No GND tabs H = No conf coat Low Rider 1x Fibre Channel 1310 nm M = Conf coat ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL MIN TYPICAL MAX UNIT Storage Temperature TS -55 +100 C 1 Lead Hand Soldering Temperature T +260 C SOLD 1 Lead Soldering Time t 10 Second SOLD Supply Voltage V -0.5 +4.5 V CC Data Input Voltage VI -0.5 VCC V Differential Input Voltage (p-p) V 2.0 V D Output Current I 50 mA O 1 The Front Load Pluggable Optical Transceiver is not soldered, rather it is the Cage and Connector that are soldered to the application card.
