4190-9010 Coupler Requirements

The 4190-9010 Coupler (271-012) is used with the 565-261 Fiber Optic Media Board, revision “C” or higher. Two 4190-9010 Bi-Directional Couplers are required per connection, one at each node.

The 4190-9010 is equipped with type ST connectors. To make type ST to type ST connections, an ST to ST coupler, by others, is required. ST to ST Couplers are available from:

Black Box, part # FO200

Fiber Instrument Sales, part # F1-8101 Newark Electronics, part # 95F2097 (or equivalent)

Notes for Tables Above:

1.Cable specifications are for 50 or 62.5 micron core with 125 micron cladding, multi- mode graded index fiber. Wavelength = 850 nm.

2.MIFL = Maximum Individual Fiber Loss. Numbers shown are for example reference only, refer to specific cable for exact specification.

3.Maximum cable length is determined by distance listed or by reaching budget value, whichever is shorter. Maximum distances listed for dual fiber cable are shorter than would be calculated. Budget using 4190-9010 Bi-Directional Coupler is the same with either size cable because the coupler input cables are 62.5/125 fiber allowing launch power to be the same.
