Technical articles for MSOs, telecom operators, system integrators and distributors buying CATV and optical transmission equipment — written by the people who build it. No marketing filler: specifications, test conditions, compliance gates and the questions to put in your RFQ.
A CATV amplifier datasheet is a price list in disguise. Read gain, output level, tilt, noise figure and derating the way a buyer should — before the PO.
CE and EN 50083-2 certification stops at the device. Five installation errors that quietly destroy CNR, CSO and CTB — and the five measurements to sign off with.
An analog switch-off is a plant event, not just a broadcast one. What changes in the headend, nodes and coax plan — and where the money, lead time and MOQ really sit.
Energy is now part of the technical evaluation in the EU and North America. Seven engineering levers that cut HFC network power cost, and the figures to demand from any supplier.
OEM or ODM? Compare one-time NRE, tooling, lead time, MOQ, design ownership and compliance before you put your brand on optical equipment.
RFoG adds RF return to a PON without rebuilding the coax plant. What EU and NA buyers must specify in an RFoG optical receiver: return path, compliance, RMA.
1310 nm and 1550 nm transmitters solve different problems. Pick the wavelength by link length, node count, EDFA amplification, cost and lead time.
EDFA amplifiers fail quietly: the first sign is usually degraded CNR at the node, not an alarm. This is the EU / NA troubleshooting sequence for the seven faults that actually occur.
MDU and hospitality properties are where FTTH RF overlay still beats an IP set-top migration. Riser power budgets, AGC windows, 1.2 GHz readiness and EU / NA compliance.
Two quotes for a functionally similar CATV optical transmitter, landing in your inbox the same week, can differ by 60–100%. In most cases neither supplier is lying. They are pricing…
European and North American operators are pushing HFC spectrum past 1 GHz — the move to 1.2 GHz is what makes DOCSIS 3.1 and the path to DOCSIS 4.0 possible without a full fiber rebuild.…
If you are expanding a headend in Southeast Asia, the Middle East or Latin America, you are almost never buying one box. You are buying a chain: a 1550nm optical transmitter, an EDFA…
In the European Union and North America, the first question is not what a 1550nm optical transmitter costs. It is whether the unit can legally be installed at all. Compliance is the gate…
If your HFC network spans more than 30–40 km, or you need to feed multiple optical nodes from a single headend, the 1550nm transmitter is almost certainly the right choice over 1310nm. The…
RF video overlay is not a legacy artefact in FTTH networks — it is still the cheapest way to deliver linear TV to a large installed base of set-top boxes. In a PON network, that overlay…
