Soptco has introduced a Four-Channel, Pluggable, LC Duplex, Fiber-Optic QSFP+ Transceiver for 40 Gigabit Ethernet Applications. This high-performance transceiver integrates four electrical data lanes in each direction into transmission over a single LC duplex fiber optic cable. The transceiver internally multiplexes an XLPPI 4x10G interface into two 20Gb/s electrical channels, transmitting and receiving each optically over one simplex LC fiber using bi-directional optics. Link distances up to 100 m using OM3 and 150m using OM4 optical fiber are supported. These modules operate over multimode fiber systems using a nominal wavelength of 850nm on one end and 900nm on the other end.

Choosing the right connectors for simplex and duplex optical fibers.

Fiber optic LC connectors are available in simplex and duplex options. A simplex optical fiber has a single strand of glass or plastic fiber, and is only capable of transmitting data in one direction. This makes it suitable for applications that only need this uni-directional capability, for example transmitting data from a sensor in an Internet of Things (IoT) system.A duplex optical fiber, on the other hand, consists of two strands of fiber, and can therefore transmit data in both directions. It may be ‘half duplex’, that can only send data in one direction at a time, or ‘full duplex’, that can handle simultaneous, bi-directional communications – for example, for an IP telephony application.
