Here’s the paragraph with another 50 wordsThe VSOL V1601E04-DP 4 Port EPON OLT is a compact, 1U 19-inch rack-mountable Optical Line Terminal designed for deployment in small or space-limited environments. It’s well suited to Triple-Play services, VPN, IP cameras, enterprise LANs, and internet service provider applications where reliable, high-performance fiber access is needed without a large-footprint chassis.

The VSOL V1601E04-DP 4 Port EPON OLT provides 4 GE (copper) ports and 4 SFP/SFP+ slots as independent uplink interfaces, along with 4 EPON OLT ports for downlink. It can support up to 256 ONUs overall, with 64 ONUs per PON port, giving it enough capacity to serve a meaningful subscriber base from a single compact unit. This split between copper and SFP/SFP+ uplinks also means network operators can mix and match connection types depending on what’s already available at the site, rather than being locked into one uplink standard.

Built as a Layer 3 EPON OLT with a redundant power option, the VSOL V1601E04-DP 4 Port EPON OLT is designed for easy deployment and flexible management, making it a practical choice for ISPs and system integrators that need dependable, high-bandwidth uplink and downlink performance in a small form factor. Its compact size also makes it easier to fit into shared equipment rooms or smaller cabinets where rack space is limited, without sacrificing the port density needed for a growing subscriber base.

For technicians managing multiple sites, the combination of Layer 3 routing and redundant power support means fewer unexpected outages and less on-site troubleshooting overall. The VSOL V1601E04-DP 4 Port EPON OLT fits naturally into deployments where a full-size chassis OLT would be overkill, yet a single-port unit wouldn’t offer enough headroom, making it a balanced middle option for growing FTTH and enterprise networks. Below are the full technical specifications.
