High Power Triport-BIDI(R) V23875-T3261-C110 Optical Triplexer Component 1310 nm Tx / 1490 nm Digital Rx with 622 Mbit/s, 3.3 V TIA / 1555 nm Analog Video Rx
Preliminary Data The V23875-T3261-C110 is an optical triplexer component designed for full-duplex digital communication over a single fiber with an additional analog video receiver. The single fiber concept saves overall system costs by eliminating one fiber, allowing for doubling of capacity without installing new fibers, and simplifying fiber management. Features * Integrated WDM filters for Tx/Rx1/Rx2 operation at 1310/1490/1555 nm * 1310 nm FP laser diode transmitter suitable for data rates up to 1.25 Gbit/s * 1490 nm PIN diode digital receiver with integrated 622 Mbit/s, 3.3 V TIA * 1555 nm PIN diode analog video receiver * -40C to +85C operating temperature range * Single-mode fiber pigtail with different connector options * Class 3B laser product * Hermetically sealed Tx and Rx sub-components for high reliability Applications * Access Networks, e.g. media converters for Fiber-In-The-Loop (FITL), Point-to-Point (P2P), and Passive Optical Networks (PON)
