GPON EXTENDER with optional EDFA for 1550nm

GPON Extender is an optoelectronic repeater developed to extend the range in a GPON Passive Optical Network. This card uses reshaping, retiming and resample to carry upstream (1310nm) and downstream (1490nm) lambdas including an optional EDFA gain block of low-noise factor. This amplifier transports any digital o analogical signal at 1550nm.

Digital diagnostic

When this card is inserted in a managed chassis (MetroSAE/MiniSAE), it is possible to monitor fiber fails and to change all optical parameters of optical amplifier (RX power, TX power, temperature, gain, etc).

Low noise factor

Noise addition in fibre is avoided by using optical reshaping in signal conditionings, unlike it occurs in other PON extender implementation RSOA based. When TELNET GPON EXTENDER includes amplification block, an optical filter limits amplification noise in 1550nm lambda, without effect on 1310 and 1490nm channels.

Supports All PON parameters

GPON Extender is capable of working under all the possibilities defined on the ITU-T G.984.2 standard. Tested against the most restrictive parameters: 32 bits guard time, 5 bytes preamble on ranged mode.

Extender Cascading

It is possible to link several GPON Extenders to increase even more the PON range.

Typical Applications

Typical ApplicationsRange extender in a GPON network acting over first or second splitting level
Extend both CATV 1550nm signal or IPTV 1550nm digital signal overlaid on an existing GPON network
Increase the number of connected ONTs up to 256 by improving the signal on the PON
Reduce CAPEX on suburban GPON deployments, reusing already exiting GPON equipment in vicinity locations
