PLANET compatible MTB-LR20 Description
EdgeOptic's MTB-LR20 compatible is a PLANET-coded 10GBASE-LR SFP+ aligned with the published PLANET MTB-LR20 specification: 20 km over single-mode fiber at 1310 nm, with DDM. The module uses a DFB laser transmitter and a PIN photodiode receiver, drives a 9 dB minimum guaranteed optical budget, and presents a duplex LC interface. EEPROM is coded against PLANET vendor identifiers so the module is recognised by PLANET switches that accept third-party SFP+ optics on their 10G cages.
TX power is held between -8.2 dBm and +0.5 dBm with receiver sensitivity of -14.5 dBm and overload at 0 dBm, supporting full 20 km links on G.652 single-mode fiber. The module operates from a single +3.3 V supply over a 0 to 60 °C operating range, matching the PLANET-published commercial-grade temperature window for MTB-LR20. DDM telemetry exposes TX power, RX power, laser bias, supply voltage, and module temperature for switch-side monitoring.
Compatible with PLANET 10G SFP+ slots on the IGS-1000-8T4X, IGS-4215-16P4X, IGS-5225-8T2S2X, GS-6311-16S8C4XR, and XGS-6311-12X. PLANET switch documentation lists 10GBASE-LR support on these 10G SFP+ cages; verify the chassis transceiver table for any platform not listed here. Common deployments include inter-building campus uplinks up to 20 km on existing G.652 SMF plant, ISP aggregation, and metro Ethernet handoffs.
The module is CE / RoHS certified and conforms to the SFP+ MSA (SFF-8431), Class 1 FDA / IEC 60825-1 laser safety, and IEEE 802.3ae for 10GBASE-LR. For the PLANET MTB-LR (10 km commercial) or MTB-TLR20 (20 km industrial -40 to +75 °C), use the dedicated SKU rather than substituting MTB-LR20.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. The MTB-LR20 sits within the EdgeOptic 10G-SFP-20 root product family. For coding requests against PLANET firmware that is not yet on file, contact our sales team.
MTB-LR20 Frequently Asked Questions
What is the difference between the PLANET MTB-LR and the MTB-LR20?
MTB-LR is the older 10 km commercial-grade 10GBASE-LR SFP+ in the PLANET MTB-Series and is published without DDM. MTB-LR20 is the 20 km commercial-grade variant with DDM. Both run at 1310 nm on single-mode fiber over a 0 to 60 °C operating range. The 20 in the SKU encodes the 20 km reach, and DDM is the secondary differentiator for switch-side optical telemetry. Order MTB-LR20 only when the link budget and reach call for 20 km; for short campus links the MTB-LR (10 km) is the correct part.
What is the difference between the PLANET MTB-LR20 and the MTB-TLR20?
MTB-LR20 and MTB-TLR20 share the same optical specification, 20 km on single-mode fiber at 1310 nm with DDM. The differentiator is the operating temperature class. MTB-LR20 is the commercial-grade module rated 0 to 60 °C and is the right part for indoor data centre and standard office environments. MTB-TLR20 is PLANET's industrial variant rated -40 to +75 °C and pairs with PLANET's industrial Ethernet switches deployed in outdoor enclosures, factory floors, and unconditioned cabinets. Use the industrial SKU when the deployment exceeds the commercial temperature window; do not substitute MTB-LR20 in environments that require the wider range.
Which PLANET switch platforms accept the MTB-LR20 on their 10G SFP+ cages?
PLANET 10G SFP+ ports across the IGS-1000-8T4X, IGS-4215-16P4X, IGS-5225-8T2S2X, GS-6311-16S8C4XR, and XGS-6311-12X are documented to accept 10GBASE-LR optics, which is the protocol class MTB-LR20 lands in. Other PLANET switches with 10G SFP+ cages typically follow the same pattern, but verify the specific chassis transceiver table on the PLANET datasheet for any platform not listed here. EEPROM coding against PLANET vendor identifiers handles module recognition; no service override command is documented for these platforms.
