dual single-mode / multimode solution to 14 Gb/s and for wide application range
single-mode up to 32 Gb/s signals providing important headroom for forward error correction and proprietary rates
Internal split ratio (to OE / to front panel) : 30/70 multimode path, 50/50 single-mode path
Data rate range : DC coupled, to > 16 Gb/s (optical-to-electrical conversion is purely analog and rolls off but continues to operate to rates in excess of 28 Gb/s. See “operating conditions” when used in the N1070A configuration.)
Insertion loss : 4.5 dB 850 nm multimode path, 4.5 dB 1550 nm single-mode path
Input return loss : 16 dB multimode path, 25 dB single-mode path
Wavelength range : 830 nm to 1360 nm multimode path, 1250 nm to 1650 nm single-mode path
Noise equivalent power 10 µW (13 dB SNR or 200 µW required to achieve lock with N4877A. Higher powers required above 16 Gb/s)
Data input/output connectors : FC/PC 62.5/125 µm multimode optical, FC/PC 9/125 µm single-mode optical, 3.5 mm electrical (output only)
Optical-to-electrical conversion gain (responsivity is reduced above 16 Gb/s) : 60 V/W minimum multimode path, 95 V/W minimum single-mode path
