Blonder-Tongue FOCN-S4S-204 Fiber Optic Compact Node 28 dBmv RF Output

The FOCN-S4S-204 is one of Blonder Tongue's high quality, cost effective, bidirectional CATV nodes featuring the latest optical receiver technology. This model is a Fiber Optic Compact Node, with 28 dBmv RF Output Forward RX 1310/1550 nm, 1000 MHz; with a Return TX of 1310 nm, 4.8 dBm DFB.

The FOCN Trailblazer Series is a low-cost, compact 2-way node designed to deliver the full array of CATV services presently available and those planned for the future. These services include video (analog and digital), high speed data and telephony. The FOCN has applications for the direct fiber transmission of CATV RF signals in MDU, industrial, government and educational facilities, or wherever a high performance compact indoor node is required. The unit is constructed with high quality components enabling it to meet or exceed its performance specifications in an uncontrolled indoor environment with wide temperature variations.

At the core of the FOCN-S4S-204 is a 1310/1550 nm optical receiver with exceptional optical sensitivity and 28 dBmv RF output at an optical input of -1dBm. This is a 2-way model with either a 1310 nm or 1550 nm DFB laser; and it has a return RF bandwidth of 5-42 MHz. Other standard features include LEDs for optical input and laser status.
