Features
- PON Extender
This card is can be inserted at any point of the PON and allows to extend a GPON signal up to 60Km maintaining additionally a 1550nm downstream overlaid lambda. This card performs a reshaping of 1490 and 1310 GPON optical signals - Regenerator 1:4
1 input regenerated into 4 separate outputs, which can losslessly multiply by 4 the splitting factor in the GPON network. - Remote OMCI management
GPON-Extender 1:4 can be managed through OMCI compliance with the standard ITU-T G.984.4 Amendment 1. - SFP optical modules
SFP optical transceivers for greater flexibility in configuring PON networks, thus enabling WDM configurations. - RSOA alternative
The electro-optical conversion performed by GPON EXTENDER does not add noise to the fibre link. It is an interesting and economical alternative to other devices developed using RSOA technology. It is possible to add multiple repeater in cascade relaxing GPON preambles in OLT. - SC/APC vs SC/PC
Card connectorization can be selected according deployment between SC/APC (recommended) and SC/PC.

Product Sheet
Regenerator GPON Extender 1:4 with SFP optical modules
GPON Extender 1:4 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.
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
· Range 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 128 by improving the signal on the PON
· Reduce CAPEX on suburban GPON deployments, reusing already exiting GPON equipment in vicinity locations
WDM in the PON: Interchangeable SFP Transceivers
The GPON Extender integrates swappable SFP transceivers, which provides a great flexibility of settings in PON networks using unconventional lambdas on to implement Trunk-PON over WDM. (Using colored transceivers).
In the example shown below can be seen 3 different PON using different optical transceivers and windows and sharing a same optical fiber using WDM.
After the shared optical fiber the signal is splitted back in a WDM multiplexer and sent to a GPON Extender configured for each of the lambdas used. Additionally, the GPON Extender 1:4 allows 4 outputs fully regenerated, thereby saving an additional level of splitting that may serve to maximize the number of users in the PON network.
