Comnet compatible SFP-LH Description

EdgeOptic's SFP-LH compatible is a Comnet-coded version of the EdgeOptic 1.25G-SFP-20DI multi-vendor Gigabit SFP transceiver. Comnet's own LH naming is unrelated to industry long-haul DWDM classification and has no connection to Cisco's SFP-1G-LH or GLC-LH-SMD product line, which is a different vendor's part with different specifications. The Comnet SFP-LH is built to a 1310nm wavelength and 20km SMF reach class with duplex LC connectors, matching the reach class and wavelength plan of the EdgeOptic 1.25G-SFP-20DI module.

This module covers Gigabit Ethernet and 1G Fibre Channel at a 1.063 to 1.25 Gbps data rate range, an average link budget of 13 dB, and DDM/DOM diagnostics per SFF-8472. The transmitter is an FP laser paired with a PIN photodiode receiver, and operating temperature is rated −45°C to +85°C for industrial deployments. The module carries CE, Class 1 FDA/IEC 60825-1, INF-8074i, SFP MSA and RoHS compliance markings. Don't confuse the SFP-LH with the Comnet SFP-LX; these are separate Comnet ordering codes. Verify the exact part number and specification against Comnet's own site before ordering.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or alternative vendor coding, contact our sales team.

Frequently Asked Questions

Does the LH in Comnet SFP-LH mean long-haul?

No. LH here is Comnet's own product naming, not an industry standard, and it has no relation to Cisco's SFP-1G-LH or GLC-LH-SMD lines, which come from a different vendor with different specifications. The Comnet SFP-LH is a 1310nm module built to a 20km reach, not a DWDM or CWDM long-haul-class part. Verify the part number against Comnet's own site before ordering so it is not confused with the Cisco LH family.

What is the difference between the Comnet SFP-LH and the Comnet SFP-LX?

SFP-LX and SFP-LH are separate Comnet ordering codes. Comnet's own documentation aggregates the SFP-LX/LH family without isolating each part's exact distance, so verify the specific reach and specification of the SFP-LX against Comnet's own site before substituting one part for the other.
